Stall protection control system of aircraft

Abstract

The invention relates to the field of flight control, in particular to a stall protection control system of an aircraft. The stall protection control system is suitable for the aircraft with a simplemechanical control system or a mechanical power assisted control system. The natural stall characteristics of the aircraft may have the risk of entering a stall and deviation state, do not meet the requirements of relevant provisions of airworthiness and affect the safety of the use of mission modes. The stall protection control system of the aircraft controls an elevator control lever by virtue of a control computer and an electromechanical actuator, wherein a fan-shaped wheel is fixedly mounted on a rocker arm of an elevator control mechanism; and the two ends of the fan-shaped wheel are separately connected to the electromechanical actuator through a steel cable. When the aircraft stalls, the control computer collects flight parameter signals and sends an instruction to the electromechanical actuator, and the electromechanical actuator rotates to drive the elevator control lever to move so as to prevent the aircraft from entering a stall state. The stall protection control system ofthe aircraft effectively prevents the aircraft from entering the stall state, reduces the steering burden of a pilot, and improves the safety of the aircraft.

Description

Technical field [0001] The invention relates to the field of flight control, in particular to an airplane stall protection control system, which is suitable for airplanes that adopt simple mechanical control or mechanical assist control systems. Background technique [0002] At present, for some aircrafts that use simple mechanical control systems or mechanical assisted control systems, the natural stall characteristics of the aircraft may involve the risk of entering a stall and deviating, and do not meet the requirements of relevant airworthiness provisions and affect the safety of the mission mode. This type of aircraft It is inevitable to enter a dangerous flight state due to possible misoperation of the pilot during flight. However, simple mechanical control systems or mechanical assist control systems cannot rely on changing the output from the control stick to the rudder surface to improve the flight quality of the aircraft, realize the flight envelope protection function,...

Problems solved by technology

In fact, even if the above three methods of stall prevention are adopted, the aircraft cannot be prevented from entering a stall state

Due to the large differences in the personal ability and psychological quality of the pilots, under the pressure of voice warning, light warning or vibrating rod warning, some pilots with poor adaptability and psychological quality are easy to operate the aircraft by mistake, causing the aircraft to enter a dangerous situation. flight status, leading to serious accidents
