SYSTEM AND METHOD OF CONTROL OF VARIABLE-PITCH PROPELLER WITH FEEDBACK

摘要

FIELD: aeronautical engineering. SUBSTANCE: system for control of variable-pitch propeller with feedback is made in form of beta-tube and blade angular position sensor engageable with it; system consists of propeller rotational speed electronic control unit and hydraulic part. System is also provided with spool valve for shifting from control with electronic control unit to control with hydromechanical limiter of maximum rotational speed of propeller. EFFECT: enhanced efficiency. 13 cl, 4 dwg
