ADTO # 70 - July 16, 1999

PART 1: Upcoming Chats
PART 2: Project News
PART 3: Safety Help for the DP-2 Ground Test
PART 4: Subscribing & unsubscribing: how to do it!


QuestChats require pre-registration. Unless otherwise noted, registration
is at:  

Tuesday, July 20, 11:00 a.m. Pacific Daylight Time:
Jim Barnes, senior system safety engineer

Jim is responsible for  making sure the tests are conducted
safely, without damage to the test vehicles wind tunnels, or anyone in
the test environment. Jim's role ensures data from these tests will be
collected successfully. He has used his skills to offer suggestions
about safety of the Wright Flyer.

Read Jim's profile and prior to joining this chat.

Tuesday, July 27, 9:00 a.m. Pacific Daylight Time:
Phillip Luan, mechanical engineer

Balances used in wind tunnel tests tell engineers how the
force of the wind affects the model. Phillip is responsible for making
sure that balances used for these tests are extremely accurate. He also
helps determine how electrical signals received during the tests are
related to the accuracy of the balances.

Read Phillip's profile and field journals prior to joining this chat.

Summer Air Travel Contest

This a special summer contest for Aerospace Team Online. This contest is
open to all students between the grades of fourth through twelfth. The
grade categories are as follows:

      4th through 8th
      9th through 12th

For this contest, we ask students to help researchers here at NASA solve
the air travel traffic problems. For more information go to

July 16, 1999

I was proud and flattered to be asked by NASA to help the Naval Air
Systems Command do a Safety Assessment of a ground test that's being done
in San Diego. They were planning a test on the DP-2 demonstrator model
built by duPont Aerospace Co. I was able to assist them in evaluating what
the hazards were and what preventive steps could be take to ensure a
safe test.

I suggested to them that it would be a very good idea before they let
this plane fly with a live pilot in it to bring the plane to be tested in
one of the wind tunnels here at NASA Ames Research Center. This will help
them make sure that the concept will work well. This will reduce risk to
the pilot, and to the program, because they will find out if the plane
needs any design refinements to ensure that will fly well.

An example of the sort of advice I gave them for the ground test related
to possible engine damage. They had done a good job of clearing the area
where they were going to do the engine run up. This would prevent fod or
foreign object damage (small things that might be sucked into the intake).
I was able to point out to them that in our experience most cases of
damage were related to loose parts from the model or parts that were not
strong enough and came loose during the test. I recommended that they
focus on parts of the model, which might become loose during the test,
especially for parts that would be heated and cooled repeatedly during the

My experience as a Navy pilot was also helpful because I have carrier
flight experience.  I was able to understand the specific safety issues
related to flight deck operations.

I really enjoyed the opportunity to collaborate with the Navy, where I
had done my military service. I think that it was reassuring to them to
consult with one of their retired pilots who understands Navy flight
