RE: [Susan/NASAChatHost] Good
morning Dave, good morning kids, I see you already have some questions
waiting for you.
Good Morning! Yep I am ready to go...

How long did it take you to finish all your studies in aeronaut? What
are the first priorities which are put up in your present work? Have you
ever thought of building a super space ship to voyage the black hole?
Why don't you make a science camp for all the interested teens who are
fond of aeronautic and give them intership and also a student of NASA?
I finished my Masters degree and Ph.D. degree in five years. This is after
the 4 years of college to get a Bachelors degrees in Aerospace Engineering.

I have often dreamed of building a super spaceship but have not had the
chance yet. There is a camp called "Spacecamp" that is a company that
works with NASA to promote interest in space.

RE: [Sarah/Greenmeadow] What are you working on now
I am working on a computer system to share all of the aerospace data that
NASA makes with the US companies and Universities.

RE: [BW/MAC-B.W./CarlisleAlternativeSchool] Hello. When were
wind tunnels first used? What improvements have been made since then?
I believe that Wind Tunnels were first used in the 1920's. But you should
check your history books to make sure. There have been many improvements
mostly in the since of the aircraft models and the speed of the wind.
[ Dave/Ames - 21
- 10:08:26 ]
RE: [Sarah/Greenmeadow] Wow! Does that include wind tunnel
data and design data?
Yes that is correct.
[ Dave/Ames - 24
- 10:13:28 ]
RE: [Sarah/Greenmeadow] Will you use the internet in the
computer system you are working on or something new?
We are using the Internet and NASA's internal networks. But the technologies
are the same. It is just a matter of who can access the systems.
[ Dave/Ames - 25
- 10:15:51 ]
RE: [Susan/NASAChatHost] Dave,
Can you say something about how wind tunnel researchers and Computational
Fluid Dynamic researchers share data?
Wind Tunnel researchers and the Computational Fluid Dynamics researchers
are all try to learn the same things - how planes fly and how to make
the fly better. They just use two very different tools - wind tunnels
and computer simulations. Basically the computer simulation is a virtual
wind tunnel that the computer simulates with a virtual model of the airplane.
[ Dave/Ames - 27
- 10:17:28 ]
You can take a look at the project web page. It is listed here.
[ Dave/Ames - 28
- 10:20:24 ]
RE: [BW/MAC-B.W./CarlisleAlternativeSchool] About that computer
system you are working on, does it allow outside companies and universities
to use that technology freely?
Good question. We have to be careful to allow only the right people to
see their data. Some data is public domain - meaning anyone can use it.
Other data is private company data that someone has paid for and it is
their's until they decide to release it. We have a set of security features
to keep access to the data controlled.
[ Dave/Ames - 30
- 10:22:44 ]
RE: [BW/MAC-B.W./CarlisleAlternativeSchool] What about hackers?
Will they have a hard time to get in?
Yep. We are trying to be very careful.
[ Dave/Ames - 32
- 10:28:41 ]
RE: [Sarah/Greenmeadow] So if I was designing a new plane
would I look at this data and get some good idesa?
Yes you could. What happens is that the companies that build planes get
some ideas for a new plane and perform some computer simulations. If that
idea still looks good they decide to spend the money to build a model
and bring it to NASA to test in a wind tunnel. They may want to compare
the data they are getting with data from an older test on a similar plane.
[ Dave/Ames - 35
- 10:31:47 ]
RE: [Sarah/Greenmeadow] What do you want to do in the future?
Oh I am not sure yet. I am enjoying what I am doing now, but I would like
to work with spacecraft again sometime. We'll see what opportunities present
[ Dave/Ames - 37
- 10:34:40 ]
RE: [BW/MAC-B.W./CarlisleAlternativeSchool] Is there any
other job you'd rather have? Is this what you wanted to do when you were
Actually, this is the job I wanted. Of Course I wanted to be an Astronaut
(and still do), but I had thought that working for NASA would be fun too.
And it is.... ;-) There are other things I would like in the future. Many
companies are working on very interesting space and airplace technologies.
To work with them would be fun also.
[ Dave/Ames - 38
- 10:35:55 ]
RE: [Sarah/Greenmeadow] How long will it take to get your
new computer system, do you know what you will do when it's finished
We have system that is working now and we are making it better and connecting
it to more and more wind tunnels and computer systems. I am not sure what
I will do when I finish.
[ Dave/Ames - 40
- 10:41:35 ]
RE: [BW/MAC-B.W./CarlisleAlternativeSchool] Are any companies
ready to sign on with this program?
Yes Boeing and McDonell Douglas (now a part of Boeing) both use it.
[ Dave/Ames - 43
- 10:45:56 ]
RE: [BW/MAC-B.W./CarlisleAlternativeSchool] Do you know what
either of these companies use the program for?
Yes, We work closely with them. The access wind tunnel test data with
it. It is made up of both software, computers, and networks and acts as

RE: [Sarah/Greenmeadow] What computer classes will help kids
be able to design airplanes
Any computer classes will help. But most important is the math and science
classes to help you understand how a plane flys and how to use math to
represent a virtual airplane in the computer.
[ Dave/Ames - 46
- 10:48:00 ]
RE: [Sarah/Greenmeadow] Do they see data as numbers or graphs?
Both. It is their choice.
- 48 - 10:50:56 ]
There is a few minutes left to this chat, send in you last questions?
[ Dave/Ames - 51
- 10:52:55 ]
RE: [Sarah/Greenmeadow] So could they tell which flap design
is working better and stuff like that?
Yes exactly. The impt. things are how much lift the wings provide the
plane (so they know how they can carry) and how much drag (to know how
much fuel to use)
[ Dave/Ames - 52
- 10:54:08 ]
RE: [BW/MAC-B.W./CarlisleAlternativeSchool] What software,
that is available to the public, could help someone design an aircraft?
There are programs like Excel and Mathcad that allow you to play with
equations and graph the answers. These are often used.
[ Dave/Ames - 53
- 10:54:57 ]
RE: [Sarah/Greenmeadow] I am kind of afraid to take physics
do you think it is important?
Yes physics is impt. Some area more than others. remember Physics is really
how math applies to the real world.
[ Dave/Ames - 55
- 10:56:03 ]
RE: [Sarah/Greenmeadow] Wow so are they trying different
angles and stuff?
Yes. That is the biggest part of many wind tunnel tests.

Thanks everyone for the interesting questions! Thanks Dave for the great
