Abstract

The problems of existing automatic control systems for aircraft propellers based on a stepper motor with a wave gearbox stem mainly from the features of the stepper motor. The proposed hybrid digital-mechanical converter is designed to increase the speed and accuracy of positioning, as well as to simplify the automatic propeller control system.

The purpose of the study is to substantiate the automatic control system for aircraft propellers based on a hybrid digital-mechanical converter.

Materials and methods of research. A hybrid digital-mechanical converter was experimentally studied, which is a positioner controlled via a digital information exchange channel; the electromechanical part of the positioner includes a new type of the hybrid electric motor. Mathematical research was carried out by the method of finite element analysis using computer software.

Results. A hybrid digital-mechanical converter designed to ensure the interaction of electronic and hydromechanical parts of advanced automatic control systems for aircraft propellers is considered. The characteristics of a wave stepper motor and an electric motor of a hybrid digital-mechanical converter are compared. A brief description of the design is given, as well as the principles of accurate positioning and performance of this system are disclosed. The electromechanical parameters of the electric motor and the algorithm of its operation are described. The presented results provide sufficiently detailed information about the hybrid digital-mechanical converter for the control system of aircraft propellers.

Conclusions. The proposed technical solutions make it possible to implement an electromechanical converter of an ACS propeller with a given speed and positioning accuracy, making it as easy as possible to control. The solutions embedded in the design of the hybrid digital-mechanical converter provide control of the positioner via a standard digital information exchange channel, the required accuracy of positioning the output shaft at high speed, duplication of control channels and power supply of the electric motor, as well as monitoring the operability of each of the control channels. With specified weight and size characteristics, the electric motor of the hybrid digital-mechanical converter provides maximum force on the rod and high accuracy of movement of the working rod due to a two-stator design with spaced phase windings. The two-stator design with spaced windings makes it possible to facilitate thermal operation in single-channel operation by removing heat losses to both stators of electric motor.
