Low-Turbulence Pressure Tunnel
NASA Langley Research Center, Hampton, VA

[ Oran/NASAChatHost - 1 - 09:40:11 ]
Hello to our early arriving ADTO/TGIR participants! Today's chat with Frank Quinto from NASA Langley Research Center will begin approximately 20 minutes. Be sure you have read Frank's autobiography at http://quest.arc.nasa.gov/aero/team/quinto.html before joining this chat. Once the chat begins, Frank will attempt to answer as many of your questions as he can, but please be patient. In the event that we begin to receive too many questions during the chat, the chat may be "moderated." This means that only a few questions will be posted at a time, until Frank can catch up with us. So we ask that you give Frank time to answer your questions before submitting new ones. As a reminder, remember to enter "Your Handle" in the box provided, before posting questions to the chat room. Once you've done this, please let us know that you have logged on for today's chat.

[ MrsMock-Mrs.Mock/MontessoriSchoolofCorona - 6 - 10:09:53 ]
My 5th and 6th graders just got here. They are ready to chat.

[ Oran/NASAChatHost - 8 - 10:10:39 ]
Hello and welcome to today's TGIR/ADTO chat with Frank Quinto from NASA Langley Research Center. When asked what he likes most about his career, Frank explains that he enjoys being able to "work with tomorrow's planes today." Currently, Frank coordinates equipment and personnel for every test in the 14-by 22-foot Subsonic Tunnel at NASA Langley Research Center. He is also helping with the development of future airplanes like the Joint Strike Fighter and the Supersonic Transport, X-33, and X-34, which will fly sometime after the year 2000. However, much of Frank's experience has also involved testing various types of airplanes, such as supersonic transports, missiles, aerospace planes, exhaust stacks and parachutes.

[ Oran/NASAChatHost - 9 - 10:11:37 ]
And now, here is Frank Quinto to answer your questions.

[ FrankQuinto/LaRC - 10 - 10:11:50 ]
RE: [Sarabeth/Briones] How doe you avoid turbulence in a wind tunnel?
We try to redure turbulence in the wind tunnel by placing a number of screens some distance ahead of the test section. These screens are very similar to the screens on the house window or door.

[ FrankQuinto/LaRC - 13 - 10:15:19 ]
RE: [AlByers/VirginiaTech-AlByers/VirginiaTech] You mentioned Reynolds numbers in your journal: when it rains it pours, referencing the necessity to scale or adjust the air flowing around a "shrunken" model to accurately simulate the flow of "normal" air around a full size airfoil. This takes you said high pressure and the use of cryogenics. Can you expound upon the science involved necessiting this use of increased pressure or crogenic fuel. I assume this somehow involves the universal gas law?
The equations for Reynolds number involves the property of the gas, density and viscosity. To increase Reynolds number, we need to increase the value of density. To do this we can either use pressure or a cryogenic gas or a combination of both.

[ FrankQuinto/LaRC - 14 - 10:16:10 ]
RE: [Sarabeth/Briones] Do you think window screen would work in a small wind tunnel with a fan?
You could probably use the screens sold at hardware stores.

[ FrankQuinto/LaRC - 16 - 10:19:27 ]
RE: [Dave-Mrs.Mock/MontessoriSchoolofCorona] Hello Oran and Frank. Our first question is, What is like to be a "Facility Manager"?
A Facility Manger is in charge of a test facility. He coordinates people and equipment for all the test that are done in the facility, such as a wind tunnel. Most of the time, it involves a lot of phone calls, e-mail, and paperwork.

In addition, I think it is a fun job because I get to work with a lot of different aeronautical test items from future X-planes to simple wings.

[ FrankQuinto/LaRC - 20 - 10:24:37 ]
RE: [AlByers/VirginiaTech-AlByers/VirginiaTech] Frank, what directed you to choose Virginia Tech versus another university for your engineering degree? Did you ever think about the Air Force Academy?
I lived in Norfolk, VA and the closest aerospace engineering university was Virginia Tech. In addition, I got to work at NASA Langley when I was in high school and a lot the people I met said that Virginia Tech was an excellent university. GO HOKIES!!!!

[ FrankQuinto/LaRC - 23 - 10:26:28 ]
RE: [Jason-Mrs.Mock/MontessoriSchoolofCorona] Are you a pilot?
No, I am not a pilot. When I was at Virginia Tech, I did the classroom part of becoming a pilot. I just did not get the chance to go flying!!!

[ FrankQuinto/LaRC - 24 - 10:28:11 ]
RE: [Amber-Mrs.Mock/MontessoriSchoolofCorona] What was it like working with Nasa Langley Research Center in High School?
Working a NASA Langley in high school was like a high school basketball player working at the Chicago Bull's gym with Michael Jordan.

[ FrankQuinto/LaRC - 30 - 10:35:37 ]
RE: [AlByers-AlByers/VirginiaTech] Frank I've read the X-33 has no wings, just vertical and angled fins for flight stability. Lift during landing is generated by the shape of the body . What did your wind tunnel test show for the X-33, was it as expected?
We encountered no surprises when the X-33 was tested for landing performance in our wind tunnel. Some of the data we got from the test was suppose to go into a flight simulation package.

[ FrankQuinto/LaRC - 32 - 10:38:12 ]
RE: [Jason-Mrs.Mock/MontessoriSchoolofCorona] Do you want to find life on other planets?
Sure, I want to find life in another planet. I would not mind if NASA sent me to go look for it. Actually, there are computerized probes that will be sent to Mars in the near future to look for life.

[ FrankQuinto/LaRC - 33 - 10:39:56 ]
RE: [Dave-Mrs.Mock/MontessoriSchoolofCorona] Will you be testing the Wright Flyer? If so what will you do?
There are no current plans that I know of to test the Wright Flyer at NASA Langley. A model of the Wright Flyer is being test or has been tested at a wind tunnel at NASA Ames.

[ FrankQuinto/LaRC - 36 - 10:44:53 ]
RE: [Al-AlByers/VirginiaTech] Awesome, so are you saying Frank that you used the data gathered from wind tunnel tests to aid pilots in learning how to "virtually" fly the X-33 in a computer simulator? How often is your data used this way for other type of aircraft?
There are many test of futuristic airplane and aerospace vehicles in wind tunnels for flight simulation. It is a lot cheaper to get the data from wind tunnels and stick in a virtual reality simulator than to build a full scale flying vehicle.

[ FrankQuinto/LaRC - 40 - 10:48:59 ]
RE: [Amber-Mrs.Mock/MontessoriSchoolofCorona] When you have ideas planes do you make models or blueprints?
We first build a mathematic model and see how well it works through a computer simulation. If it does well, it then goes to be design as a "computer blueprints" using a CAD system. The model is then built and then tested in a wind tunnels. If everything goes well, it will then become a full size airplane. All this make take several years.

[ FrankQuinto/LaRC - 41 - 10:50:02 ]
RE: [Chris-Mrs.Mock/MontessoriSchoolofCorona] I am in 4th grade. What is your favorite plane?
I do not have a particular favorite airplane, but I do like the military airplanes.

[ FrankQuinto/LaRC - 42 - 10:51:04 ]
RE: [Randy-Mrs.Mock/MontessoriSchoolofCorona] What kind of airplanes do you test?
We test all kinds of airplanes. Every airplane must takeoff and land, so it must be tested at low speeds.

[ FrankQuinto/LaRC - 45 - 10:54:03 ]
RE: [Caleb-Mrs.Mock/MontessoriSchoolofCorona] Have you had problems testing planes?
We encounter some problems when we test models. We try to resolve any problems with the test. We also try to solve any problems that the "life size" airplane encounters. If our wind tunnel cannot solve it, we can always go to other wind tunnels.

[ FrankQuinto/LaRC - 47 - 10:55:12 ]
RE: [Chris-Mrs.Mock/MontessoriSchoolofCorona] How long have you worked at NASA?
I have worked at NASA Langley for a little over 18 years.

[ FrankQuinto/LaRC - 50 - 10:57:04 ]
RE: [Randy-Mrs.Mock/MontessoriSchoolofCorona] Do you like testing the airplanes? What do you like best?
I think it is fun to test airplanes. What we test in our wind tunnels today, I will probably see flying in 5 to 10 years from now. So, I get to see the future pass by my wind tunnels.

[ FrankQuinto/LaRC - 55 - 11:01:52 ]
RE: [Al-AlByers/VirginiaTech] Frank, what do you feel has been your biggest challenge to overcome as flight director at Langley. Isn't that what engineering is all about, developing solutions to problems with no "ready" answers?
Engineers are really problem or mystery solvers. In almost every wind tunnel, you are trying to resolve a mystery. As always, when one questions is answered more come up. You hope that your education and previous experience can help you solve most of these mysteries. In addition, I am not working alone here. There are a lot of smart people that are with me. If I can't find the solution, I am sure one of my co-workers will find the solution.

[ FrankQuinto/LaRC - 57 - 11:04:37 ]
RE: [Caleb-Mrs.Mock/MontessoriSchoolofCorona] What is a wind tunnel?
A wind tunnel is where engineers can test models of airplanes. They are tube with a test section, where the model is mounted for testing, and a fan to create the wind.

[ FrankQuinto/LaRC - 59 - 11:06:02 ]
RE: [Al-AlByers/VirginiaTech] Frank, thank you for your time and informative answers. I too know have to go get ready for class. Go HOKIES! I work with Jeff Seaton and Chelly Canright out of Langley (education) as a Graduate Student Research fellow..your right it's an awesome place to work! Thanks again.
Good luck!!!

[ MrsMock-Mrs.Mock/MontessoriSchoolofCorona - 54 - 10:59:32 ]
