Problems solved by technology
However, the commands issued by the override control board override the flap control computer to execute another set of control strategies, which has special requirements for the driver, and there is a certain risk of use; the flap control part is divided into many modules and weighs a lot; the flap drive The execution part adopts the form of power drive and hydraulic brake, which increases the complexity of the system and the overall reliability is not high

Embodiment Construction
[0027] Main technical scheme of the present invention is as follows:
[0028] Such as figure 1 As shown, for the aircraft with multiple flaps on the trailing edge of the wing, the flap control system can be divided into three main parts: 1 flap control part, 2 flap control part and 3 flap drive transmission execution Parts are connected with each other by cables.
[0029] For the 1 flap control part, according to the characteristics and functional requirements of the flap control, the flap control handle and the flap spare control board are used. In the normal control state, the flap joystick is used to realize multi-gear control command output. In the standby control state, the control command output of the flap standby control panel is used. A flap backup switch and a flap backup control knob (or switch) are arranged on the flap backup control board, and the flap backup switch realizes switching of control commands between the flap joystick and the flap backup control kno...

The invention belongs to the field of flight control systems of military and civil aircrafts, and provides a high-reliability and low-cost flap control system method, which comprises the following steps of: dividing a flap control system into three parts, namely a flap control part, a flap control part and a flap driving transmission execution part, which are connected with one another by adoptingcables; for the flap control part, a flap control handle and a flap standby control panel are adopted; for the flap control part, two sets of flap control computers and two sets of flap motor controlmodules are arranged; for a flap drive transmission execution part, a flap motor drive unit, a flap transmission line system, a flap ball screw actuator, a wingtip brake device (WTB) and a flap position sensor (FPSU) are designed. The development complexity of a flap control system is reduced; the flap control system is high in reliability; the flap control system is low in overall research and development cost.
Description
technical field [0001] The invention belongs to the field of flight control systems of military and civilian aircraft. Background technique [0002] Aircraft flaps mainly complete the function of increasing lift and increasing resistance during takeoff or landing, and the flap control system is the main means to realize this function. Improving the reliability of the flap control system and reducing the cost of the flap control system are system design The goal that has been pursued. This technical solution provides a relatively reasonable solution by combining actual engineering technology application experience and domestic and foreign technical development levels, which not only meets the reliability requirements of aircraft flaps, but also achieves the purpose of reducing costs. [0003] The flap control system can be divided into three parts: the flap control part, the flap control part and the flap drive execution part. [0004] In a civil aircraft, the flap control ...
