[ Susan/NASAChatHost - 9 - 10:03:32 ]
Gutten tag Daniel!!

[ Craig/Ames - 10 - 10:03:47 ]
RE: [Susan/NASAChatHost] Craig I received an email question from Jackie Trump, she asks Is it possible to test a paper airplane in a model wind tunnel?]
Yes, as long as you make the paper airplane stiff enough to withstand the forces created by the airflow.

[ Craig/Ames - 11 - 10:06:14 ]
RE: [Susan/NASAChatHost ] If not what material would be good to construct a model from?]
Metal, wood, styrofoam and plastic are all good materials to make a model airplane out of. A real good place to start would be to buy a model airplane from a hobby store, and put that in your wind tunnel.

[ Craig/Ames - 13 - 10:11:09 ]
RE: [Susan/NASAChatHost] What have you been working on lately?
Lately, I have been working on a paper I'm going to be presenting at a Conference in London, England in September. When I get that finished, I hope to start work on the data acquisition system for the Wright Flyer

[ Craig/Ames - 16 - 10:23:28 ]
RE: [Susan/NASAChatHost] Jackie also asked if it will be possible to simulate the 27 mph winds that the Wrights experienced in their first flight?]
I actually built a wind tunnel when I was in high school. I found that using a furnace blower fan provided the best airflow for the wind tunnel. I found an old one my grandfather had. You could probably get by with an ordinary fan, like everybody uses in the summertime to cool off the house.

[ Susan/NASAChatHost - 19 - 10:31:09 ]
Welcome Melissa, while you are waiting for your answer from Craig, you can read the bios of some people working with Craig at http://quest.arc.nasa.gov/aero/team/

[ Craig/Ames - 22 - 10:38:01 ]
RE: [Melissa-Melissa/UniversityofMemphis] Hi Craig, I'm a physics major at the University of Memphis, and I'm not sure where I'll go from undergrad school. Are there many people working in your area with bachelors degrees, and how many women do you work with (directly or otherwise) in your profession? ]
Most people start their careers at NASA with only a bachelor's degree. Many then go on to get their Masters or PH.D through programs support by NASA that will pay for your education. Many aerospace companies like Lockheed-Martin have similiar programs. I personally, have just a bachelor's degree, and I have found it not to be a detriment, although I suspect I'll never be a manager until I get the higher degree. NASA is actively seeking qualified women for all sorts of ocupations. In the engineering areas, about 1 person in 10 is a women, but these numbers continue to change toward a more favorable ratio all the time, as more women enter engineering related fields.

[ Craig/Ames - 24 - 10:44:08 ]
RE: [Patti/CJHS] Hi Craig, On the Wright Flyer, is this being tested only for that replica (in other words, to gain information on the Wright Bros. plane), or do you hope to learn something to further knowledge in modern aeronautics?
The test we'll perform on the Wright Flyer is strictly to learn about the Wright Flyer. The test techniques we're going to use are tried and true, and have been in use for about 25 years. We are, however, taking advantage of new technology (like web chats) to share this knowledge and history to people outside of NASA.

[ Susan/NASAChatHost - 25 - 10:44:40 ]
RE: [Melissa-Melissa/UniversityofMemphis] Is physics a viable degree in your particular field? Also, what kind of GPA is generally considered acceptable? ]
Melissa, did you read the careers section? http://quest.arc.nasa.gov/aero/background/careers

[ Susan/NASAChatHost - 28 - 10:50:47 ]
RE: [Melissa-Melissa/UniversityofMemphis] Susan, no I didn't. Just saw who was going to be on a few minutes ago, thought I'd try to get in on the conversations. Does that section describe minimum GPA's? ]
No but it does describe some of the sorts of ongoing research and has a list of urls.

[ Craig/Ames - 29 - 10:52:32 ]
RE: [Melissa-Melissa/UniversityofMemphis] Is physics a viable degree in your particular field? Also, what kind of GPA is generally considered acceptable? ]
People with a degree in Physics have good opportunities to get into Aeronautics at NASA, although they would probably be called on to do more of the theoretical work. A Master's Degree in Aerospace or Mechanical Engineering in addition to your degree in Physics would probably be most useful. As far as GPA is concerned, a 3.0 or higher is desirable. However, it is also been my observation that the colleges tend to put more emphasis on the GPA than the industry. Having the degree is usually considered more important than having the high GPA that goes along with it.

[ Craig/Ames - 32 - 11:01:01 ]
RE: [Susan/NASAChatHost] Jackie asks if it is possible could a person be a part of the test for the purpose of learning the wing warping?
Jackie - For safety reasons we don't allow anyone to be in the tunnel during a test. We do have a set of video cameras that permit full view of the model. We'll be monitoring the wing warping very carefully to see how the model responds to the deflections.

[ Susan/NASAChatHost - 30 - 10:53:26 ]
Are you interested in aeronautics?

[ Melissa-Melissa/UniversityofMemphis - 33 - 11:03:00 ]
Susan, yes, I am. I really enjoy the physics, and all of my study partners are in engineering as there aren't many of us physics majors at the U of M. I enjoy seeing the work they're studying, and aeronautics is something that has always fascinated me, but I've yet to learn much in that field. My GPA is close to a 3.0, and is improving steadily as I was recently diagnosed with a learning disability and have since made dean's list each semester, knowing what the problem had been in the past. In short, yes I am interested, have been for a while, but would prefer not to be simply in the theory, would like to be involved hands-on in addition. Thanks.

[ Susan/NASAChatHost - 35 - 11:05:55 ]
Melissa , good luck to you , if you go to the NASA home page you can find info about openings at NASA, http://www.nasa.gov

[ Craig/Ames - 37 - 11:08:36 ]
RE: [Susan/NASAChatHost] Craig as I understand it for this test a little motor has been rigged up to change the shape of the wings.
Yes, it will pull on the cables in the same way Wilbur or Orville would have scooted side-to-side on the cradle they laid down in while flying the aircraft. Pulling on those cables caused the wings to warp. Since our pilot will be a mannequin, the motor will help him to warp the wings.

[ Craig/Ames - 39 - 11:10:55 ]
RE: [Melissa-Melissa/UniversityofMemphis] Craig, for brain-storming, do you guys ever invite outside guests to sit in and participate in group meetings? Sometimes someone who doesn't know as much about your field can come up with questions or ideas that you guys might not, because we DON'T know the limitations you do, and sometimes it can lead to something big. Does that make sense? And is there ever the opportunity to do such?
Melissa - We are very fortunate at NASA that we can stand/sit around and shoot the breeze without answering to a time clock. You are right, a lot of good ideas come from seemingly unrelated subjects presented by non-experts.

[ Craig/Ames - 41 - 11:11:44 ]
RE: [Susan/NASAChatHost] Thank you Craig I hope you will do another chat with us so we can learn more about the Wright Flyer!
Sure, my pleasure
