EXPERIMENTAL DESIGN OF A FLUID-CONTROLLED HOT GAS VALVE

Abstract

Effort is described toward development of a hot gas jet reaction valve utilizing boundary layer techniques to control a high pressure, high temperature gas stream. The result has been the successful design of a hot gas valve in a reaction control system utilizing fluid-controlled bi-stable amplifier principles and required no moving parts in the gas stream. The experimental design approach and results achieved are de scribed with no particular attempt being made to develop the theory. Valves have been fabricated and successfully tested to control gas at pressures to 1200 psi and temperatures to 2350 F with flow rates as high as 0.16 lb/sec at the highest temperatures. Efficiencies comparable to standard valving techniques have been realized.
