RESEARCH AND DEVELOPMENT OF PNEUMATIC JET RELAY SYSTEM FOR PROPULSION SYSTEM CONTROL

摘要

Fluid jet devices with no moving mechanical parts, which can serve as rugged sensing and control elements in advanced air-breathing propulsion systems, are the goal of this study. A basic approach for a quasi-static prediction for the dynamic behavior of controlled jets is presented, and implemented by a digital computer. Experimental results of a basic investigation of the impingement of a turbulent jet onto a flat plate are given for a wide variation of Reynolds numbers, and compared with theory. The static and dynamic interactions of jets with receiver ports are discussed, including theoretical and experimental results.
