Embodiment Construction

[0020] The present invention will be described in further detail below.

[0021] A fly-by-wire flight control system with high safety and low cost, including a command sensor, an actuator controller, a flight control computer, an actuator and a rudder surface position sensor, wherein:

[0022] There are 4 command sensors, namely left command sensor 1, left command sensor 2, right command sensor 1, right command sensor 2, and each command sensor has 2 redundancy. The left command sensor and the right command sensor are mechanically connected through the intermediate release device for linkage. This configuration of command sensors ensures the versatility of the command sensors in addition to maintaining the minimum number of safety requirements. It is also provided with a 4-degree redundant deceleration handle command sensor.

[0023] Actuator controllers are configured with 4 sets, namely left actuator controller 1, left actuator controller 2, right actuator controller 1, ri...

Abstract

The present invention belongs to the field of the airplane flight control system design, and relates to a flybywire control system with high safety and low cost. The technical scheme of the system provided by the invention comprises the following steps: performing reasonable allocation of a command sensor, an actuator controller, a flight control computer, an actuator, a control plane position sensor and the type and the quantity of cables, and at the same time centralizing the functions of devices and performing optimal design of the interface relations of the devices. The security index is realized, the weight of the system is mitigated, the number of functional spare parts is reduced, the arrangement length of cables is decreased, and the cost of the flybywire control system is effectively reduced.

Description

technical field [0001] The invention belongs to the design field of aircraft flight control systems, and relates to a high-safety and low-cost fly-by-wire flight control system. Background technique [0002] With the gradual development of aviation technology, the flight control system on the aircraft has also developed from a mechanical control system to a fly-by-wire flight control system to a digital flight control system. While the flight control system is pursuing the safety of new technology, it is also striving to improve the economy. Therefore, more aircraft still use the fly-by-wire flight control system that takes into account both safety and economy. The safety index of the fly-by-wire flight control system is guaranteed to be 10% higher than the normal mode -7 and emergency modal 10 -9 On the basis of this, building a reasonable fly-by-wire flight control system will have a greater impact on the economy. [0003] The main function of the fly-by-wire flight con...
