RHRC EXHIBITS AT AIAA RENO MEETING
January 5-8, 2004 - Rolling Hills Research
participated in the 42nd Aerospace Sciences Meeting of the American Institute of
Aeronautics and Astronautics (AIAA) in Reno, Nevada, this week. The AIAA
meeting provided an opportunity to display the new 2nd generation
design of the Model 0710, University
Desktop Water Tunnel. The new design features a single piece, welded
steel frame, that is similar to the frame used for the Model 1520 and 2436
Research Water Tunnels. All three sizes of the RHRC water tunnel family
now use a new flow conditioner design that allows the honeycomb to be rotated to
clear air-bubbles. This makes it very convenient to maintain excellent
flow quality in the test section.
RHRC also used the AIAA meeting to introduce the
latest prepared experiment for the Model 0710 water tunnel, the
Bernoulli experiment. The experiment uses a
series of pressure transducers are arranged in a converging / diverging nozzle
to measure the change in pressure, and velocity, through the length of the
nozzle. The transducers are read by an analog to digital converter board,
and displayed with RHRC's
software. The divergence angle of the nozzle can be adjusted to show the
onset of separation.
thanks to RHRC's friend and supporter, Dr. Abdi Khodadoust, who provided digital
photos from the AIAA meeting.
