Three-channel digital electric steering engine system with projectile diameter of 40mm

Abstract

The invention relates to a three-channel digital electric steering engine system with the projectile diameter of 40 mm. The three-channel digital electric steering engine system aims to solve the problem that the performance of an existing three-channel digital electric steering engine system with the elastic diameter of 40 mm cannot completely meet the requirements in a narrow space of the three-channel digital electric steering engine system with the elastic diameter of 40 mm due to the fact that a turbine worm reducer scheme, a gearbox reducer scheme and a ball screw reducer scheme are adopted in the three-channel digital electric steering engine system with the elastic diameter of 40 mm. The system comprises a rudder room, N control surfaces, and a circuit module, N motors, N speed reducers and N potentiometers which are arranged in the rudder room, n > = 3; the circuit module comprises a control circuit board, a driving power circuit board, an electric connector, M circuit board mounting columns, M circuit board mounting blocks, M first mounting bolts and M second mounting bolts. The motor is a permanent magnet brush direct current hollow cup servo motor; the speed reducer adopts a harmonic speed reducer; the potentiometer is a precise rotating conductive potentiometer.

Description

technical field [0001] The invention relates to an electric steering gear system, in particular to a 40mm bullet diameter three-channel digital electric steering gear system. Background technique [0002] The rudder system is the key component of the missile's attitude control and ballistic orbit change, and it is the executive body of the missile's direction control. The rudder system generates corresponding aerodynamic and aerodynamic torque on the rudder by controlling the rotation angle of the actuator, so that the projectile can fly quickly according to the predetermined trajectory. The performance of the rudder system is closely related to the missile strike accuracy. The steering gear system consists of a controller, a driver, a motor, a deceleration mechanism and a feedback sensor. During the flight of the missile, after the missile onboard computer issues a command to adjust the flight attitude, the rudder system starts to work. The controller of the rudder system ...
