Abstract: Deflection of a supersonic jet stream engine exhaust by a shock wave resulting from insertion of a small obstruction or a gas stream into the jet stream. This provides flight path deflection of the vehicle powered by the engine.

Abstract: Ballistic range dust erosion testing apparatus wherein a saboted test specimen is fired through a calibrated test environment and then captured intact in a deceleration tube for the extraction of dust erosion data. A dust dispenser consists of a vertical hopper with a sliding, reciprocating gate valve having a stationary plate and a sliding plate with coincident holes aligned for metered dust dispersion during reciprocal movement of the sliding plate. Adjustment of moving plate stroke length and frequency (RPM) in combination with phase adjustment with the stationary plate provides a desired dust orientation in space through which the test specimen passes. Controllable vibration in three orthogonal planes applied to the dispenser sweeps the dust grid in space so that the entire area of the target is subjected to a uniform dust impingement, even in a vacuum. Data is obtained by microscopic examination as well as by weighing the eroded specimen.
