Yay!

So school is done...for the fall. Now comes the build blitz for Team Phelan in the Spring. We were all happy to find out at the end of exam week that we were cleared to build. Here are some pictures from our computer models.

This is the cover of our CDR document.














And here is a taste of the CMARC model. CMARC simulates pretty much everything aerodynamic except for drag, go figure. What you see here is a coefficient of pressure during the cruise portion of flight.





Next are some of the CAD models.















Ooooo, ahhhhh!















All dimensions are in inches (boo not metric).

One thing I think all of us were excited to learn was the professor's desire to create a removable wing-tip design. Our team leader presented on a wing tip designs and what they did for an aircraft, so the professor called up the authors and wanted to know if they were interested in using our vehicle as a platform for experimental data collection. Under normal flight we will use the wingtip shown on the right.





For now I'm enjoying a nice long break out in the great state of Colorado. It can't be beat!

Times Change

So this semester I've been enjoying a class in Fluid Physics which emphasizes earth science applications, inevitably some aerodynamics shows up too. In an attempt to get away from the long derivation based lectures the professor shows videos on fluid mechanics that were made back in the late 50s and early 60s. I very much enjoy these videos and can't wait till the next Wednesday class each week; the semester is coming to an end which is unfortunate with respect to this part of my week.

Anyway I get my hands on these videos (VHS) and convert them to a digital format so I may enjoy them for years to come, they really are a treat to watch. And one thing I have come to admire is the immaculate hand writing of the narrator/host, Ascher Shapiro. His penmanship is in start contrast to much of the hand writing I see on a daily basis, especially that of my professors. I got to thinking (during class usually) how things like this change, maybe it's my romanticized view of by gone eras, or maybe it really is that people in general had better writing back then. I can't help to think as I peck away at some letter label buttons how little I actually 'write' and how much life now depends on typing. I always appreciate aesthetics, although some might say I don't, but I find it very rare to see a nice piece of penmanship. I know I am not gifted with this ability, but after the last few weeks I have become more aware of my own writing.

I have always thought my writing was mediocre at best, but it seems to get the point across. And that's the thing, I think people feel like writing is such a slow use of time that they hurry through it with out much concern for it's ability to communicate to other readers. I know I am guilty of this. I would say that 99.99% of my writing is solely for personal use; notes are essential to students, and even then I am always critiqued for how sparse and dense my class notes are. But now after watching the wonderful strokes of Dr. Ascher Shapiro I am very aware of what can be done with practice of the arm-hand-eye coordination, I will strive for this for some time to come.

As I sit here writing this out I can only think of the modern equivalent to what I have identified, the rush to finish typing because it feels like such a drain of time. Again I am guilty as charged. Many times reports and papers have to get done and nearly all of those many times a deadline is breathing down your neck, the result, poorly written text. (See! I'm not sure if I even got the punctuation correct on the end of that last sentence.) Now the thing I fear! People who can't physically write clearly enough so that other people can read it, and people who can't express their ideas to get their point across in the first place. I don't like what popular technology does to some parts of our lives.

Do I make myself clear?

Back To The Grind...

...Only 3 more wild weeks and one fluid filled day left until the end of the semester. This is both good news and bad news. Good because it can't last too much longer, bad because there's so much to do in such a short time; the questions is, can Team Phelan get it done in the remaining 2 weeks!?! Yep that's right 2 weeks and counting until Critical Design Review. Eeeeek!

That being said the Thanksgiving break was a very welcome change of pace for several days. I had a great time with Mom, Pop, and Alice; I also got to spend some time with Grand-Pa, Sara, Scott and Carrie.

Thursday was spent talking, cooking, eating, playing with dogs, walking, and being a tour guide.
Friday was an enjoyable day of bike riding, walking, and lumber jacking. Alice turns out to wield a mighty maul and saw. Watch out for those trash cans, they'll get'cha!
Saturday passed with the retrieval of a new kitchen table form Pineville, and a driving/walking tour of my olde stomping grounds.
Sunday mmmmm banana bread!

A great break with a little hard labor, a little exercise, and lots of good food and relaxing times.

No EC for me...

After several months of being on the fence about my participation in the Everglades Challenge 2008, it is now official; I will not be on Mullet Key March 1, 2008.


Here's why:
1) Aerospace senior design is eating up lots of time. If I were able to have a spring break, I would not be able to take the full week off anyway, needless to say a couple days before the break actually started.

2) I am already booked solid for the Thanksgiving and Winter breaks so I won't be at school to do work, and apparently to be worthy of good work I have to be at school? Anyway I would much rather spend my whole Thanksgiving and Winter breaks away from school than spend some of that time away and still not be able to do the EC08.

3) And the last reason, for now, its that the entrance fees are increasing. Seeing that I am going to graduate soon I need to start really saving money until I have a job or some other source of support.

Maybe I can be the 'ground crew' for the Stewarts' and Adam, that'll give me a fun thing to do during the week.

Sigh, what great times I had last year.

Pineapple Poll


According to a recent study 50% of college students prefer pineapple chunks over pineapple slices. I find this very interesting.

What do you prefer? What is your age group?

I look forward to finding out!

Vie

So I thought I would put up a quick post.

School has been keeping me busy most of the time, senior design is going to be a demeaning course, but the results will be satisfying (hopefully). This weekend should be a good one. Going out to Wilson to drive Dan around in the back of Puta for a XC R/C flight, then Sunday I will get back in the swing of Orienteering. We'll see how my running legs hold up.

The following weekend I'll head home to see everyone at a small family reunion, Spencer's clan is even coming!!! That Saturday is the annual COK Canoe-Orineteering meet so I plan on doing that, possibly with Lesley, a cousin. The following Monday is a proposal for Senior Design, and then the next Saturday is another team NORSA event in the Uwharrie mountains. Adam, Alan, Tim, and I are going to participate in the 2007 Gold Nugget Adventure Race; we will have to paddle, bike, run, orienteer, and think our way through an estimated 12 hour course. It should be a blast from teh past!

And then last, but the best is the fact that I am going out to CO for Fall break to spend a day and some with the folks, Spencer, Rose, and their kids. This should be a great time; I hope to take some of them up for a glide over Boulder. But even better yet I am going to see Alice for the first time since July. I can't believe it has been that long, but it has been so long since we last laid eyes on one another. Right now the plan is to meet up with her for breakfast/brunch on Friday and then the two of us will drive down to C Springs for the remainder of the weekend. I can't wait for fall break!!!

Also this weekend I'm rebuilding the wheels for my mountain bike (Giant Yukon). This is something I've been meaning to do since August, but time and desire only allows for it to happen now. After having ridden by new road bike for a couple weeks, it was a shock to get back on the mountain bike with crappy wheels. Either way I feel like an absurd SUV driver when I make the switch to the Giant; it's also taken some time to re-acclimate to the turning characteristics, but the track stand is still there. I love being able to pull up to a light and just sit there without having to dismount; the track stand is progressing on the Trek, but is a bit tougher.

Anyway I shall go now. Hopefully pictures will be abundant for the next few weekends.

Music and life are great.

Pamlico Swirly-Whirly: Foux Du Fa Fa

Well I must say the Pamlico Swirly-Whirly was quite a trip and a great way to spend the longer weekend.

The adventure really started Friday afternoon where Adam, Alan, and I started to look for a place to stay that night. Adam called a connection through the NCSU sailing club to see if we could sleep on the floor of the maritime museum in Manteo, but that fell through because the guy was out of town. Next stop was Couchsurfing.com, here we had great success finding options. After sending out 6 or 7 requests for a place to crash that night in the Manteo area one fellow, Alan, responded saying that we could stay at his place; great we’re all set for the night. All we had to do now was pack up our stuff and drop it off with my new friend (Ryan) Neely who happened to be camping on Ocracoke Saturday and Sunday nights. I initially invited him along on the trip because he is also a biker, instead he was going to go camping with a bunch of friends and he was nice enough to transport things for our Saturday night, plus he provided a space for us to stay at the NPS campground. Thanks a bunch Neely!

Well after we packed up a headed out to drop things off a Neely’s place, but he wasn’t picking up his phone, so we spent some time looking for him and deciding what to do without stuff. We ended up piling the bags in the bushes in front of his car with the hopes that no one would see them and steal them. That was taken care of then we hit the road in earnest. As soon as we got on the beltline there was very heavy traffic, but this eventually cleared up when I-40 split from I-440. We made our exit on Hwy. 64 without much traffic and made our way through most of Wake County before we encountered another slow up. This time it was a pickup that had run off the side of the road into the woods; needless to say it didn’t look pretty. We also encountered a home built trimaran being trailered towards the coast and this brought on a discussion of EC 2008 as Adam is now interested in doing it this year. Traffic was still moderately heavy on the way down there, but that could be expected for Labor Day weekend. We took our first stop at a shopping center to get dinner at Subway and let Alan get money at the SECU; but the bank was closed, and the Subway didn’t open until the next day, it was brand new. So we went further down the road looking for a place to eat when we came across a DWI check point. It was strange to have a checkpoint so early in the night, but at least the state is serious about the issue. Next stop was in a small town to get gas, and by that time grab some dinner.

Alan and Adam opted for the microwave burritos, while I went for the Wheat Thins, pound cake, and sugar wafers; now we were set food wise. As we neared Kill Devil Hills, where Alan and his puppy Lopez live, it started to hit us. How crazy was this guy going to be, and should we be prepared for a duel; but we knew it was going to be ok and figured he was thinking the exact same things. So we got there without a problem, met Alan and his crazy 6 month old German Shepherd, talked with him for a while and then crashed; he gave us some good local advice of where to go and what to do for the next couple of days. Alan had the perfect setup for us we each had our own bed to sleep on which was great for our early morning start Saturday.

We woke up Saturday, filled up on water, left a cantaloupe for Alan, and drove over to the Mariner Museum. We spent about an hour making the final pack and prepping the bikes for the journey to come, and eating our own cantaloupe, yum yum!

Off we went East on 64, and then South on 12 with a nice 15ish MPH tailwind. The first big obstacle of the ride was the bridge over Oregon Inlet which is apparently in very poor shape; they are always dredging the channel under the bridge because mother nature doesn’t like it. We noticed riding over the bridge that we had two choices in the event of a crash; go over the railing into the water (a long way down), or fall left into traffic and hope they stop quickly enough. Fortunately we didn’t have to find out what would happen. We made our first stop about 30 miles into the ride (1.5 hours) at a rental shop where an acquaintance of Adam’s used to work, but he was not to be found. On we went further south to kite point which is a big kite boarding location on the sound side of the barrier island. Then we made a quick stop for Adam to stretch and me to check on a clicking noise emanating from my real aluminum rear wheel.

Next stop was the 208 foot tall Cape Hatteras lighthouse, a quick stop, no climbing because of cost, but it was cool to see it again in its new location, after 15 years. Shortly after the lighthouse we were rode straight to the front of the line for the Ocracoke Island ferry.

After a quick ride over to Ocracoke we hit the fresh pavement of the island. I pulled ahead of Adam and Alan for about 10 minutes just to get in a good hard pace for a bit. Eventually we made it to the NPS campground and checked to see if Neely was there yet, but no luck so we rode another couple of miles into town, checked out the harbor and then grabbed an enjoyable lunch. I was feeling for something on the light side, so I wanted a hummus sandwich, but wanted a grilled chicken breast on it, instead I ended up with a chicken sandwich with hummus on the side. We also all enjoyed a pitcher of Yuengling and a pitcher or Mimosa before we hopped back on the bikes to make the upwind journey back to the campsite. By that time Neely and friends had arrived so we did the meet and greet for a bit, and then setup camp with a little improvisation due to high winds, lack of tent spikes, and dysfunctional tent poles.

After getting everything situated we suited up and headed for the surf where we all body surfed, with varying degrees of success. But really it was about washing all of the grit and road grime off more than anything. The water temps were nice, and the sun started to peak out by this time so it wasn’t too cold once we got out and were quickly dried by the stiff winds. Back to camp to get a rinse of shower, cook some pasta, grab some things from the town grocery, and fend off wild embers while making smores. I also took a quick trip towards town to check out the island airstrip and some of the aircraft on the ramp. By this time the three of us were pooped, so we hit the sack. Adam and I had to get cozy in a poorly designed tent; two 6’+ people in a small round tent is interesting. The sleep wasn’t great, especially considering the previous nights’ accommodations, but anything was welcome considering the day to come.

We woke up at 5:15 to break down camp, fill up on water again, and the make a break for the 6:30 ferry. We made it down there with plenty of time to spare, paid our $3 each to ride the ferry and hopped aboard for the 2.5 hour (really 3) crossing of the sound. There was one spot a little ways out of Ocracoke what was pretty cool to see (sorry no pictures). First there was an island where the dry sand was being blown across the exposed tidal sand which created a nice spectacle in the morning sun. Furthermore there was a sand bank extending off of the island where the waves were meeting at a 90 degree angle. Once they met it was cool to see a Cartesian grid of peaks and troughs traveling in unison through the water. Neato! Also aboard the ferry were three other NC State students who were biking the same route we did; they were unsupported though, telling us of their adventures to find a place to sleep on Ocracoke, getting the boot from the ranger, and then sleeping in someone’s yard between two sheets for the 3 of them. We were lucky that Neely was camping on Ocracoke for the weekend. Also on the ferry we realized that we needed to put on sunscreen and that Alan had left his at the campsite that morning, so our first objective was to find a gas station to buy some.

Once off of the ferry we had to do some navigating to find the right roads, and even then we had trouble; the whole day was going to be long because of the strong head wind this time. We were planning on riding across Lake Mattamuskeet, but missed the turn; I didn’t care though because we got to see a crop duster in action right over our heads. Eventually we asked for some directions and back tracked to find the cross lake route. There were some big swarms of gnats that we rode through and most of the one that hit me stuck to my sweaty arms. The origin and history of Lake Mattamuskeet is not very well understood, so now I’m curious; I’ve wanted to see the lake for several years now after trying to figure out what the largest lake in NC is, but now I want to know more about it. If you look at an overhead shot (care of Google) you can see some curiosities in the land, but nothing I’ve found so far says anything about human intervention; anyway I digress.

So on the north side of Mattamuskeet is the little farming town of Fairfield were we stopped to stock up on calories, and buy some sunscreen. Well they certainly had the calories, but no sun block for sale; however the attendant was nice enough to let us borrow hers. We slathered up and chowed down and got underway towards Engelhard. We ended up stopping there at a rest stop (some picnic tables in the shade) to fill up on H2O again and take a break. While sprawled out on a picnic table I saw one thing that I would have never guess I would have see in such a remote place, a French speaking family; it turns out they are likely Canadian because of their Quebec license plate. It was nice to hear the French in a conversational manner. After the stop in Engelhard we rode for what seemed like forever on several stretches of very straight and very long roads. We did take a quick break on the road side when Adam figured out what the noise was in my real aluminum rear wheel; it turned out that there was a piece of metal wire that had pierced my rear tire and was knocking on the bike frame, it was lucky that is didn’t hit my tube.

In what we were expecting to be a mile more, it turned out to be more like 5, was Stumpy Point. We took a nice rest break here initially because my knee started acting up, but it ended up being a good stop. We all filled up on H2O again, and ate some energy; I got some pain meds down, and found a can of Fanta, so as my nick name says I drank it. At the north end of Stumpy Point there was sign telling us it was only 22 more miles to Manteo; in reality it was more than that because of the route we had planned, but a finite number was good to see. This boosted my morale, but at the same time the wind settled down so we made good time for the next 15 or so miles until we got to the 64/264 junction.

So we were about to turn onto the road that took us on the old Hwy. 64 bridge and I was looking back to check traffic when I ran into Alan who had slowed up. The only damage was a couple bent spokes and a sore foot, but the wheel was still true, so we were good to go. I did come close, not that close though, to getting run over by a minivan; let’s just say that my life didn’t even come close to flashing before my eyes. We rode up to the old bridge, did out business and then did the last few miles to our jump off point. Adam and I made it there without a problem, but when Alan didn’t show up we went looking for him, he eventually showed up having missed the turn. All told we did 200+ miles in 12.5 hours of riding; 4.5 hours the first day and 8 the second day with very similar mileages. That tells you about the winds while riding!

We did the break down and pack up, decided to eat something, and then go fly Alan’s parafoil kite at Jockey’s Ridge, some big sand dunes. Dinner wasn’t what I was hoping for, I was hungry, and I didn’t feel like arguing, so I did it I ate 3 Big-Mac’s from McDonalds; that was the first time I had eaten there in many years. The burgers looked like crap and tasted the way I remembered them, not great by any means, but at that point food was calories and I needed them. Afterwards we had fun at Jockey’s Ridge trying to float down the dunes, watching the hangliders, and the sunset; there was even a full sized paraglider out here floating down the slopes. After getting even messier at Jockey’s ridge we went to a kite boarding shop which had an outdoor shower where we rinse doff and cleaned up some, also the sun was finally setting there. Then we hit the road and made it back to Raleigh about 10:30.

Once back in Raleigh we unpacked and grabbed swim suits to go soak in some friends’ hot tub which felt great on our tired legs. And of course much sleep ensued.

Check out my Pamlico Swirly-Whirly photo album; or you can see Alan’s interpretation of the trip and photos. Also check out the video Adam put together, and the original video that the music came from. If you were wondering about the subtitle, Foux Du Fa Fa, this was a song that was running through all of our heads for the whole trip.

Summer

Finally I have some photos to share with the web. The summer has been great so far and looks to remain that way.

I am in Boulder, CO for the summer working as an intern for NOAA. There are several other NOAA in terns and then an equal number of students who are working at NIST for the summer. Most of us live in the same apartment complex which affords us some great free time activities and drama. Biking, hiking and all around fun are had nearly every night and especially on the weekends.

Personally I traveled out here a week earlier than everyone else to get a glider rating add-on to my pilots certificate. By the end of the second day I had already logged 4 solo flights in one of Mile High Gliding's SGS 2-33A gliders. This progress continued through earning my certificate, and the weekend after that I was training in a Grob 103 Acro III.

Yesterday I went to go get checkout one more time in the 103, fly with Alice, and then go fly the single seater Grob 102. The soaring forecast looked promising for Saturday, but nothing really developed, so it was a day of gliding, not soaring. The G102 is a tight squeeze for me physically, but it is a blast to fly; I can't wait to fly it when there is actually lift out there.

I've told other folks, other than Alice that I'll take them up, so I'm thinking about getting some insurance so I can fly the faster, quieter G103 ship instead of the SGS 2-33A (a factor of 2 performance difference).



On the more outdoorsy side of things several friends and I have made it a point to have several good rides each week. 2 weeks ago was by far the most intense, here was the schedule:
Sunday - Airport and NCAR
Monday- NCAR
Tuesday- Flagstaff
Wednesday - city ride with lots o wind
Thursday - sleep
Friday - the end of Four Mile canyon via Boulder canyon
Saturday - Walker Ranch via Flagstaff

Just to give you an idea of how steep Flagstaff is, I clocked a speed of 55 MPH on the way back from Walker Ranch with my GPS. That's no pedaling right before a hair pin turn...so much fun.

Also there have been some hike in the local area. The one that I really love is through Settlers Park at the mouth of Boulder Canyon. As Ethan and Lucas put it "it's an underwater castle". Once you hike the short trail and then do some rock climbing, you are rewarded with a lovely view of the plains, especially the between sunset and night.

Work is great too, I'm able to work in a lab everyday, and while the tests are running I work on some calculations, or data analysis. In a couple of weeks we should be deploying our system to the Niwot Ridge Biological Preserve to measure the methane habits of a sub-alpine forest.

And last but not least are the pictures care of Alice (check them all out here):

Boohoohoo

I learned of some unfortunate news yesterday with respect to the NCSU Aerial Robotics Club. Our pride and joy, the '12footer' crashed on Sunday. Check out the AR website for a video link and some explanation. Here are some still photos taken by the helpless pilot, Alan, at the crash site. It wasn't Alan's fault by any means, most signs point to a servo battery failure; it must have been a heart wrenching feeling to see it go down without any control.





This first image is created from the autopilot datalog and screenshot, which was then fed into Google Earth. The RC runway is in the fore ground. The 12footer went down about 1/3 of a mile away from the flight pad. The colored dots are the autopilot way-points.









Here you can see to bulk of our autonomous system: the engine and autopilot are on the left side; (no-so) safety switch, GPS antenna, computer antenna, and autopilot wireless card are in the center of the picture.







Most of the 12 footer came through the tall pines, some of it remained with the trees.











This is one of the wings, they got obliterated along with everything else.




Sigh


We are already underway with the mobilization of our backup system. Stay tuned to the AR website for updates on the Wide-body 8footer.

O

Due to he unfavorable winds which canceled a scheduled Aerial Robotics flight test, Tim and I were able to partake in our first adventure race on Saturday. The event consisted of riding our bikes around Raleigh, Cary, Umstead S.P., and Crabtree County Park to find a series of clue based check points. Time had trouble with cramping which cut our race a little short, but it was still fun to go ride 35 miles with an objective. This was my first taste of hopefully many more Bike Orienteering events to come. After the ride back to school Time and I had finished 45 miles on our bikes for the afternoon.

Beginning of the Storm

Today started out just like any other day, bike to the AR lab, find something to do before class, and the goto Broughton 2211. But the day certainly didn't end up in a normal fashion. Since the semester is wrapping up I didn't have to go to PE(Ultimate), so I spent my time getting the last bits of information for my Stability and Controls class project.

After an hour or so I headed back to my room to masticate (chicken spaghetti) and finalize my portion of the project. That was done in due time so that I could head over to Centennial Campus for my Structures project testing (pictures to follow). The test went well overall. Matt and I missed the stiffness by alot, missed the estimated weight by a factor of 2, and our strength to weight was off by a factor of 1/2. The ultimate load was probably the closest of any groups, we held 90lbs. with an estimate of 100lbs. The waiting portion of the testing was not fun, one group ahead of us took more than an hour to 'break' their structure, really it just oozed apart at the glue joints...shotty construction. Ours on the other hand deformed over 1.25" and when it failed you knew it. For me, I heard the pop and then the whiz of a quarter and peice of scrap aluminum fly by my head. For anybody interested in our material of choice Matt and I used Rohacell foam with Marinepoxy as the bonding agent.

After than was over I had to 'help' Matt finish his portion of he Stab. & Control project...don't ask.

I dropped off the project in Broughton and then headed back to my place to get ready for some pick-up Ultimate! I had a good time playing, it had been nearly 2 years since I had played any good pick up and it was nice to be in the swing of things.

With all of my running around today I think I set a record for number of time in and out of my room at 5. Usually I can plan better than that, but today was fairly chaotic day.





























Notice how circular holes turn into ovals and the displacement gage is embedded in the structure after failure.
