FLUERIC DIVERTER VALVE,
Abstract
The experimental work leading to the development of a flueric diverter valve (FDV) is described. The work has shown that a gas flow can be controlled in a 'three-dimensional' aerodynamic valve that has no moving internal parts. In the Phase I effort, flow tests of various power nozzle configurations were completed, and a subscale model of the FDV was evaluated under simulated V/STOL operating conditions. A major objective is design of a unit of practicable size that will operate at subsonic and supersonic pressure ratios. In flow tests using cold gas at 0 to 45 psig, a subscale model of the FDV diverted 100 percent of the flow with the control orifice vented to atmosphere. The overall valving efficiency defined in terms of a thrust recovery factor for various nozzles (not optimized) typically measured 0.83. (Author)
