AI Technical Summary
The existing propeller control systems for small and medium-sized turboprop engines are mechanical-hydraulic and lack electronic control functions, which cannot meet the requirements of modern fly-by-wire flight control systems.
An electronically controlled propeller speed regulator was designed, including an oil supply mechanism, a drive shaft, a worm gear mechanism, a stepper motor, and a control piston. The stepper motor is driven by an electronic controller to adjust the movement of the worm gear mechanism, thereby controlling the opening and closing of the oil leakage hole and realizing electronic control of the propeller.
It achieves integrated electronic control of the engine and propeller, meeting the integrated electronic control requirements of modern aircraft propellers.
