Embodiment Construction

[0009] The present invention will be described in further detail below. A method to solve the electromagnetic compatibility of the aircraft's horizontal tail rudder control system, based on a control terminal circuit installed in the electronic cabin of the fuselage, a twisted pair shielded transmission cable and an actuator installed at the front end of the horizontal tail as a load terminal circuit The horizontal tail rudder surface control system composed of control circuits is characterized in that the steps for solving the electromagnetic compatibility of the above-mentioned control system are as follows:

[0010] (1) Series variable resistance box; a variable resistance box is connected in series between the twisted-pair shielded transmission cable and the load end circuit, and its resistance value ranges from 0 to 400Ω;

[0011] (2) Determine the resistance range of the variable resistance box when the load-side circuit can work normally; connect the power supply of the...

Abstract

The invention belongs to the design field of airplane system circuits, and relates to a method for solving electromagnetic compatibility of a horizontal tail rudder surface control system of an airplane. The method comprises the following steps: serially connecting a variable resistance box; determining a resistance range of the variable resistance box when a load terminal circuit can normally work; and optimizing a resistance value. Aiming at solving the problem of the electromagnetic compatibility in the prior system, the invention ensures stable operation of the system, convenient implementation, wide adaptability and low cost.

Description

technical field [0001] The invention belongs to the field of aircraft system circuit design, and relates to a method for solving the electromagnetic compatibility of an aircraft horizontal tail rudder control system. Background technique [0002] When there is system-level electromagnetic compatibility in the general aircraft system design circuit, it is often used to change the frequency of the controller, change the characteristics of the transmission cable, change the shielding characteristics of the cable, change the grounding form of the cable, change the wiring form of the cable, etc., and these methods are all It is only a solution to a specific circuit and a specific environment, and its use range is narrow, so it is difficult to adapt to the complex and changeable electromagnetic environment. The horizontal tail rudder control system of a certain type of aircraft is composed of the control terminal circuit installed in the electronic compartment of the fuselage, the...
