Problems solved by technology
There are "four deficiencies" in the unpowered flight of modern civil aircraft: lack of power, lack of information, lack of time, and lack of forced landing sites
After the engine fails, the aircraft will decelerate rapidly under the action of aerodynamic resistance, shortening the time for the aircraft to stay in the air; on the other hand, the supply time of the emergency power system that provides energy at this time is certain, and the time left for the pilot to make an emergency landing is very limited

Embodiment 1
[0247] The invention is used to complete an emergency landing task after all engines of an aircraft engine fail. The initial altitude of the aircraft is 2400m, the speed is 130m / s, and the aircraft track deviation angle is 56°; the altitude of the target airport is 370m, and the approach angle of the runway is 14°; the horizontal relative distance between the initial position of the aircraft and the target landing point is 23.5km. Seven seconds after the ground simulator flight test started, all engines were turned off to simulate the failure of all engines. Simulation results such as Figure 7 with Figure 8 shown.

The invention discloses an auxiliary driving system and method for civil aircraft full-engine failure forced landing. The system comprises a full-engine failure judgment subsystem (100), a return ability evaluation subsystem (200), a return stage decision subsystem (300) and a return instruction autonomous generation subsystem (400). The full-engine failure refers to an unpowered gliding state entered after all engines of the aircraft fail accidentally. The full-engine failure judgment subsystem (100) prompts a pilot whether full-engine failure occurs or not according to the state of an engine, and then the return ability evaluation subsystem (200) screens a landing site according to the remaining energy of the aircraft for the pilot to make a final decision. The return stage decision subsystem (300) and the return instruction autonomous generation subsystem (400) autonomously generate an aircraft control strategy and a state instruction to be tracked by a pilot in real time accordingto the direction and the flight speed of the aircraft away from a landing point, and inform the pilot through screen display to assist the pilot in completing a full-engine failure forced landing task.
Description
technical field [0001] The invention relates to a method for assisting piloting of an aircraft, more specifically, a method for assisting the pilot of a civil aircraft to select a landing site, plan a return trajectory, prompt control strategies and instructions, and safely land to a selected location after all engines of the civil aircraft fail. Systems and methods for determining a landing site. Background technique [0002] Engine failure refers to the state that the engine stops working and cannot generate power due to mechanical failure, electronic system failure and other reasons when the aircraft is performing a flight mission. There are "four deficiencies" in the unpowered flight of modern civil aircraft: lack of power, lack of information, lack of time, and lack of an emergency landing site. After the engine fails, the aircraft will decelerate rapidly under the action of aerodynamic resistance, shortening the time for the aircraft to stay in the air; on the other h...
