LASER Velocimetry System for Flow Measurement. Advanced Short Takeoff and Vertical Landing, ASTOVL model n the 9x15 foot Low Speed Wind Tunnel, LSWT

The 9x15 low speed tunnel tests take off and landing of aircraft. The laser velocimetry system for flow measurement show here, with the color blue and green lasers, measures engine exhaust that comes back up from the ground. The STOVL model n the 9x15 low speed wind tunnel, building 39, is similar to the British Harrier aircraft.

A spectrally resolved Rayleigh/Mie scattering diagnostic was developed to measure temperature and wing span wise velocity in the vicinity of an ASTOVL aircraft model tested in the Lewis, now Glenn, 9x15 Low Speed Wind Tunnel. Shown is a Fabry-Perot interferometer that uses only the blue light from a laser to measure static temperature and velocity near the lift nozzles and suction systems.

Tour of the Glenn Research Center’s 8x6 Supersonic wind tunnel and the 9x15 Low Speed wind tunnels by senior management. The tour group is the Dayton Development Coalition representing JobsOhio. Photo was taken in the lobby of building 54 with the display of the QueSST (Quiet, Efficient SuperSonic Transport) model in the foreground.

Ultra High Bypass Integrated System Test Testing of an Ultra High Bypass Ratio Turbofan model in the 9-by 15-Foot Low Speed Wind Tunnel. Pratt & Whitney designed the experimental engine to meet new efficiency and noise reduction targets for commercial aircraft set by NASA and the Federal Aviation Administration. The 9-by 15 tests analyzed two noise reduction technologies.
