A spectrally resolved Rayleigh/Mie scattering diagnostic was developed to measure temperature and wingspan wise velocity in the vicinity of an ASTOVL aircraft model tested in the Lewis, now Glenn, 9x15 Low Speed Wind Tunnel. This was done for the Phase III hot gas ingestion study of ground-effect flow-field on such aircraft during hover or vertical landing.

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.

The Sierra Space Plane, Dream Chaser, suspended by a crane sits just inside the overhead door of the ISP (In Space Propulsion) test facility at NASA GRC-ATF. Once lifted and lowered into the test chamber, it will be exposed to the harsh cold conditions of space for testing in extended periods of time.
