RESEARCH AND DEVELOPMENT OF FLUID AMPLIFIERS FOR TURBOPROPULSION SYSTEM CONTROL

Abstract

Techniques for sensing the relative threat of flow instabilities in jet engines have been a long sought after goal. This is the final report of a study aimed at determining the feasibility of certain types of fluid jet amplifiers used as fast pressure and temperature sensors. The more theoretical aspects of the report include a study of the statics and dynamics of the interaction of a fluid jet and a receiver port, the dynamics of the controlled deflections of jets in fluid amplifiers, and the dynamic analysis of fluid systems. The more applied aspects include the design of a fluid relay stall-cell sensor, a fluid diode possibly useful for sensing blade wakes or stall cells, and a unique reference-frequency pneumatic oscillator.
