This book was released on 1970 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The servosystem design of a high-response airflow bypass valving system for supersonic mixed-compression inlets or other industrial or aerospace pneumatic systems is described. The valve utilizes a multislotted plate to achieve flow area change with minimum stroke and mass of moving parts. The servosystem utilizes a hydraulic piston-in-cylinder actuator close-coupled to a two-stage electrohydraulic servovalve. Using electronic compensation the small-amplitude response of the system, modulating 14 percent of its full flow area, is flat within 0 to -3 dB to 110 Hz. (161 cm [to the second power] ). A mathematical model of the system is presented and analytical responses are compared with experimental data.
