Abstract:

	 The purpose of this project is to provide innovative methods for simulating propulsion
effects in aerodynamic research conducted with models in magnetic suspension wind
tunnels. The feasibility of various techniques of generating exhaust jets of appropriate
characteristics was evaluated in Phase I. Judgments of feasibility considered the
ability of the selected methods to generate model flow rates and velocities of propulsive
jets for a variety of aircraft configurations, flight regimes, and model scales.
	Four concepts of remotely-operated propulsion simulators were examined. Three conceptual
designs involving innovative adaptation of conventional technologies (compressed
gas cylinders, liquid, and solid propellants) were developed. The fourth innovation,
namely, the laser-assisted thruster, which can potentially simulate both inlet and
exhaust flows, was found to require very high power levels for small thrust levels.
This concept needs further research.

Potential Commercial Application:

Potential Commercial Application: Applications would be in conducting aerodynamic
research in wind tunnels equipped with magnetic devices for model suspension.
