Good Morning! When you are designing, what is the first thing you work
[ Dale/Ames - 7
- 09:00:27 ]
Good morning. For the most part, I don't get to design aircraft. When
I am designing an experiment, the first thing I do is sit down and think
about the problem that I am trying to solve so the experiment will answer
that question the most efficiently.

RE: [Susan/NASAChatHost] How's
the work on Boeing 777 coming?
We are reviewing the data from the 777 test. There are still a few minor
errors in the data. We are also designing new parts for the model so we
can test the model again next year.
[ Dale/Ames - 11

RE: [Sarah-Patti/DiscoveryCharterSchool] how long does it
take to build an aerospace model?
A brand new model usually takes at least one year depending on its complexity.

RE: [Angel-Vincent/WashingtonElementary] Good Morning! When
you are designing, what is the first thing you work on?
Angel, What is your favorite subject and what grade are you in?

RE: [Sammy-Vincent/WashingtonElementary] What is the biggest
and strongest craft that you have helped design?
I have worked on the Boeing 747 which is the largest commercial aircraft.
All of our wind tunnel models are built to the same requirements so they
won't break in the wind tunnel
[ Dale/Ames - 18
- 09:07:23 ]
RE: [Susan/NASAChatHost] Are you
working on a schedule for the 777?
Yes, we have a schedule for the 777. We are hoping to finish the modifications
by October and the model is scheduled to be tested next spring.

RE: [Mike-Deborah/YpsilantiCOPE] Have you ever worked on
a model that ever actually made it into commercial aircraft production?
All of the models that I have worked on have been models of commercial
aircraft that are flying today

RE: [Roy-Patti/DiscoveryCharterSchool] Hello, my name is
Roy Enjambre, i am in 6'th grade. My first question is When do you plan
to retire from the aerospace business?
I will be eligible to retire in 12 years. However, I have a son who is
only 4 years old so I may have to work longer until he is out of school
[ Dale/Ames - 24
- 09:11:20 ]
RE: [Deborah/YpsilantiCOPE] Why do you use the 12 foot pressure
tunnel for your tests?
By increasing the pressure inside the wind tunnel, we make the model think
it is bigger. The 12 Foot can be pumped up to 6 atmospheres which makes
the model think it is 6 times bigger.
[ Dale/Ames - 26
- 09:12:26 ]
RE: [Minerva-Vincent/WashingtonElementary] What is your favorite
part of your job?
Actually being in the wind tunnel watching the data plot on the computer
screen to see if everything is working correctly.

RE: [Daniel-Deborah/YpsilantiCOPE] What kinds of software
do you use in your job? What language do you use to program (like the
10,000 line program you wrote)?
For the most part, I use software on a Mac computer. Word, Excel, Powerpoint,
Project, Photoshop. The language that I used to program with is Fortran.
It is still used a lot by engineers but newer languages such as C++ are
slowly replacing Fortran.

RE: [tyler-Patti/DiscoveryCharterSchool] Good morning I am
tyler fredrickson I would like to know what kind of food they eat in space
I have never been in space and don't work on space projects so I really
don't know. From what I have read and seen on TV, the early astronauts
didn't have a very large selection and everything was freeze dried. The
Shuttle astronauts have a larger selection and the food is prepared better.

RE: [Israel-Vincent/WashingtonElementary] Do you think you
will ever get to design a spaceship. Do you think that you could design
a spaceship that will be able to go to the moon and back with passengers
so when I am older I can take a trip to the moon????
I don't have any experience with space ships so you probably wouldn't
want to fly on one that I designed. But you are in luck, because there
are people that are working on projects that will hopefully build such
a space ship someday.
[ Dale/Ames - 39
- 09:20:43 ]
RE: [Alyson-Alyson/McMurrayElementary] What things do you
use to make space shuttles?
I really don't know what goes into the shuttle. The shuttle is covered
with thermal tiles to protect it from the heat of re-entry. The tiles
are made of a light-weight ceramic material that doesn't melt or burn
when heated to very high temperatures.
[ Dale/Ames - 43

RE: [Roy-Patti/DiscoveryCharterSchool] What has been the
most exciting model you have made?
We have a model of a cargo airplane that uses the engine exhaust to help
lift the airplane. The model has two engine simulators on it. Each simulator
weighes about 80 lbs but will produce 1400 lbs of thrust. The fan spins
at speeds of 54,000 rpm.

RE: [eric-Alyson/McMurrayElementary] To make a spaceship
is there such thing as a space ship blueprint?
When we build a rocket or space ship we have blue prints for it. If you
are asking is there a generic blue print for space ships, I would say

RE: [sarah-Patti/DiscoveryCharterSchool] do your kids plan
to be aerospace engineers?
At this point, my children are not old enough to know what they truly
want to be. My youngest is fascinated with airplanes. He loves to visit
the wind tunnel. The oldest wants to be a computer programmer and the
middle one wants to be a lawyer today.
[ Dale/Ames - 49
- 09:26:31 ]
RE: [eric-Alyson/McMurrayElementary] About how many people
work on a space ship at a time
The shuttle carries 7 to 10 people on most missions.
[ Dale/Ames - 50
- 09:27:32 ]
RE: [Luis-Vincent/WashingtonElementary] What kind of materials
are used in airplanes and where do you get them?
Most airplanes are made out of aluminum, steel, and other metals. Metals
are refined from ores mined out of the earth.

RE: [Deborah/YpsilantiCOPE] What are mini-tufts? Explain
more, please, about how flow visualization works. How are the oil, china
clay and mini-tufts used?
Tufts are pieces of yarn that are taped or glued to the model. As the
wind blows over the model the tufts follow the wind and show the engineer
where the air is going. To minimize the effect of the tufts on the model,
we have developed mini-tufts, very thin monofilament (fishing line) that
is almost the size of human hair.

RE: [Vincent-Vincent/WashingtonElementary] Have you ever
played in the wind tunnel? Or maybe you will get in trouble if you tell
I have never played in a wind tunnel. Some of the tests have been fun
but a wind tunnel can be a dangerous place if mistreated.

RE: [Dane-Deborah/YpsilantiCOPE] What are the major challenges
in high lift research / design?
Sorry I missed your question. The challenge for high lift is to make the
flaps as simple as possible and as efficient as possible. Two flaps will
always work better than one flap but if you can get 80-90% with one flap
the single flap will be better since the part count and weight will be

RE: [Deborah/YpsilantiCOPE] What have been your most exciting
/ rewarding moments and your most disappointing / frustrating moments
in your career?
Right now is one of the frustrating moments in my career. The program
that I am working on is being stopped a year early and we have had several
sever budget cuts so we will not get to complete the program that we developed.
I have had numerous exciting moments in my career. When I got accepted
to graduate school and hired by NASA was probably the best.

RE: [sarah-Patti/DiscoveryCharterSchool] what made you think
of becoming a aerospace engineer and how did you find it enteresting?
When I was in the 4th grade, I decided that I wanted to be an astronaut.
Back then the only way to be an astronaut, was to be a military pilot.
Unfortunately when i got older, I found out that I could not pass the
physical for a military pilot (I had allergies). But I had been studying
about aircraft and I decided that I loved airplanes and so I became an
aerospace engineer. Today, you can become an astronaut without being a

RE: [Sergio-Vincent/WashingtonElementary] When you work with
stuff in the wind tunnel, do you ever get static electricity from all
that wind friction. Does anything spark? Is that something that can be
For the most part the models are electrically grounded so I have never
experienced a shock or seen a spark. When we are doing flow visualization
with oil or china clay, a spark could be dangerous if the oil or kerosene
(part of the china clay) happened to catch fire.
[ Dale/Ames - 90
- 09:56:21 ]
RE: [Roy-Patti/DiscoveryCharterSchool] Has any of your models
been built any bigger for other people to use?
Lots of models get built of the same aircraft configuration. That way
the model is properly sized for the particular wind tunnel. We usually
have to have several models to get all of the desired answers.

RE: [tyler-Patti/DiscoveryCharterSchool] what is a wind tunle?
A wind tunnel is a tool we use to test aircraft models. It is typically
a closed tube that kind of looks like a doughnut that is hollow. A big
fan inside moves the air around the inside of the doughnut and over the
wind tunnel model. Check out the NASA web sites for more on wind tunnels
