Problems solved by technology

[0002] Generally, the actuators of fixed-wing UAVs use analog control servos, which are characterized by low cost, compact structure, and simple voltage control. At the same time, their shortcomings are also very obvious: low precision, low power, backward control methods, and reliability. Poor sex, etc.
Therefore, this analog steering gear cannot meet the requirements of the unmanned helicopter control system for the actuator

Embodiment Construction

[0016] Refer to attached Figure 1~3 , an unmanned helicopter main steering gear system is composed of 3 main steering gears and 1 steering gear controller, wherein the main steering gear is composed of a moving screw 1, a steering gear housing 2, a motor 3, and an installation base 4, and the steering gear The machine housing 2 and the motor 3 are installed on the installation base 4, and the moving screw 1 is installed in the steering gear housing 2. Through the transmission gear inside the installation base 4, the rotation of the motor 3 is converted into the axial movement of the moving screw 1 .

[0017] Two lugs of the installation base 4 of the main steering gear of the unmanned helicopter are installed on the upper box, which is a fixed part; the upper end of the moving screw rod 1 is installed on the automatic tilter of the unmanned helicopter, and the movement of the screw rod drives the automatic tilter.

[0018] The moving screw 1 has an effective stroke of 85mm, ...

Abstract

The invention discloses a main steering gear system of an unmanned helicopter, which relates to an executing mechanism of an unmanned helicopter. Rotors are controlled by flight control servo elements mainly by means of variable-pitch control of a main rotor of the unmanned helicopter. The main steering gear system comprises three main steering gears and a steering gear controller; each main steering gear consists of a movement lead screw, a gear body shell, a motor and a mounting base, the gear body shells and the motors are mounted on the mounting bases, the movement lead screws are mountedon the gear body shells, and rotation of the motors is converted into axial movement of the movement lead screws by the aid of transmission gears inside the mounting bases; and the gear controller comprises a microprocessor dsPIC30F6011, a logic gate array GAL22V10, a power driving module L6203 and an interface conversion device MAX3160. The main steering gears of the unmanned helicopter have theadvantages of high system precision and power, advanced control mode and high reliability.

Description

technical field [0001] The invention relates to an unmanned helicopter main steering gear system, which relates to an unmanned helicopter executive mechanism, which is mainly used for variable-pitch control of the main rotor of the unmanned helicopter, and the rotor is controlled by a flight control servo element. Background technique [0002] Generally, the actuators of fixed-wing UAVs use analog control servos, which are characterized by low cost, compact structure, and simple voltage control. At the same time, their shortcomings are also very obvious: low precision, low power, backward control methods, and reliability. Poor sex, etc. Therefore, this analog steering gear cannot meet the requirements of the unmanned helicopter control system for the actuator. Contents of the invention [0003] The object of the present invention is to provide a kind of unmanned helicopter main steering gear system for above-mentioned deficiencies, is a kind of main rotor control steering...
