Embodiment Construction

[0029] The implementation and use of specific embodiments of the present invention are described in detail below. It should be understood, however, that the specific embodiments described are merely illustrative of specific ways to make and use the invention and do not limit the scope of the invention.

[0030] According to the aircraft nose wheel turning control system of the present invention, comprising:

[0031] A turning control unit, which reads the current state parameters of the aircraft through sensors or buses and calculates the required nose wheel deflection angle to achieve the target turning angle;

[0032] a turn control valve receiving commands from the turn control unit; and

[0033] The steering actuator, the steering control valve moves correspondingly according to the instruction received from the steering control unit, so as to output corresponding pressure to the steering actuator to complete the deflection of the front wheels.

[0034] Wherein, the stee...

Abstract

The invention provides an airplane front wheel turning control system which comprises a turning control unit, a turning control valve and a turning acting cylinder, wherein the turning control unit reads an airplane current state parameter through a sensor or bus and calculates a front wheel deflection angle required by reaching a target turning angle; the turning control valve receives a command from the turning control unit; and the turning acting cylinder makes a corresponding movement according to the command received from the turning control unit so as to output a corresponding pressure to the turning acting cylinder to complete deflection of a front wheel. The invention further provides an airplane front wheel turning control method, which uses the airplane front wheel turning control system.

Description

technical field [0001] The invention belongs to the technical field of aircraft nose wheel turning control, and more specifically, the invention relates to an aircraft nose wheel turning control system and an aircraft nose wheel turning control method. Background technique [0002] The nose wheel steering system is one of the main systems of aircraft ground control, which plays a very important role in realizing aircraft ground turning control and reducing aircraft takeoff and landing accidents. [0003] At present, the turning control process of the aircraft when taxiing at high speed is basically as follows: figure 1 As shown, according to the target turning angle, the pilot uses the pedals to control the rudder deflection angle through the turning control unit SCU, that is, mainly depends on the force of the rudder to deflect the overall effect of the aircraft. [0004] The existing aircraft turning control laws are not perfect. When the aircraft is gliding at high speed...
