Aerospace Team ONLINE

UPDATE #22 - May 8, 1998

PART 1: Upcoming Chats
PART 2: Survey Coming
PART 3: Greetings From the DNW --
PART 4: Subscribing & Unsubscribing: How to do it


Monday, May 11, 1998, 1:00 p.m. - 2:00 p.m. PDT
Steve Smith, Aerospace Research Engineer

Steve does aerodynamic performance prediction and design of
subsonic transports. He spends about one third of this time doing
experimental research in wind tunnels, and about two thirds of
the time in computational research.

Wednesday May 20, 1998 12:00 p.m.- 1:00 p.m. Pacific Time:
Mina Cappuccio, Aerospace Research Engineer

Mina is working in the area of propulsion airframe integration, or how to
fit the engine on the plane. Currently she is working on the High Speed
Civil Transport.

Wednesday May 20, 1998 1:00 p.m.- 2:00 p.m. Pacific Time:
Liza Alderete, Education Technology and Multimedia Manager

Liza Alderete has worked in wind tunnels, simulations and now is in the
Education Department at NASA Ames Research Center. She recently produced a
CD called Exploring Aeronautics which will be available in June.

Registration information is at
Liza's bio will be at http://quest.arc.nasa.gov/aero/team/alderete.html
next week.

NASA's Quest Project - the K-12 Internet Initiative
is actually having two full days of chats on May 19 and 20
please visit http://quest.arc.nasa.gov/common/spaceday.html
for more information.


Next week we hope to send a email survey to Aerospace Team Online users
to get your feedback on the project. The survey results will be used to
decide whether to continue the project and how it can be improved.
Your input will be very highly valued.  Please take the time to fill out
the email form or you can respond online, a form will be placed in the
Teacher's Lounge Area.

[Editor's Note: Larry Young is an aerospace engineer at NASA Ames Research Center. He specializes in rotorcraft aeromechanics research. Aeromechanics research is the study of the aerodynamics, dynamics, and mechanical aspects of helicopters and tiltrotor aircraft Read his bio at http://quest.arc.nasa.gov/aero/team/young.html ]

May 6, 1998

Greetings from the DNW (Duits-Nederlandse Windtunnel) in The Netherlands
(also known as Holland).   The DNW is a German and Dutch owned and
operated wind tunnel.  The DNW wind tunnel is particularly well suited for
aeroacoustic research for various types of vehicles such as automobiles,
airplanes, and rotorcraft.

NASA, U.S. Army, and Boeing researchers are currently at the DNW wind
tunnel studying the aerodynamics and acoustics of a 1/4-scale V-22 Osprey
tiltrotor proprotor.  This proprotor is being tested on the isolated rotor
configuration of the Tilt Rotor Aeroacoustic Model (TRAM).  This is the
third week of a four week test entry.  This is the second time the TRAM
test stand has been tested in the DNW.  Earlier, preliminary testing
occurred in December 1997.

The information from this test will be used to help develop a new
generation of quieter and more efficient tiltrotor aircraft.  Tiltrotor
aircraft are of great research interest to NASA.  They have possible
civilian as well as military applications.  Data from the DNW tests will
be used in conjunction with data from future tests in the National
Full-scale Aerodynamics Complex at NASA Ames Research Center to aid in the
development of these quieter tiltrotors.

Right now the TRAM test team is working long hours trying to acquire all
the data needed to meet the test objectives and make the test a success.
The data being acquired is one of a kind information.  Gigabytes of data
is being measured and stored for future study.  The two key challenges of
any rotorcraft test team is, first, keeping the model 'healthy' and
operational and, second, reviewing and evaluating the quality and
comprehensiveness of the test data being measured.

On a more personal note, Holland is a beautiful country in the spring
time.  Holland is located adjacent to Belgium and Germany in Western
Europe.  Holland is famous for its tulips, wind mills, canals, and dikes
that protect it from the sea.  Whether it is weekend exploring the
countryside or its largest and best known city, Amsterdam, Holland is a
great place to visit (or, more correctly in the case of the TRAM test
team, work in).

Tot Straks!! ('See you later' in the Dutch language)
