A driving assistance system and method for forced landing of civil aircraft with all engine failures

Abstract

The invention discloses an auxiliary driving system and method for forced landing of a civil aircraft with full engine failure. The system includes a full engine failure judgment subsystem (100), a return capability evaluation subsystem (200), and a return stage decision-making subsystem (300). ), the return command autonomously generating subsystem (400). The failure of all engines refers to the unpowered descent state that the aircraft enters after an accident in which all engines fail. The all engine failure judgment subsystem (100) prompts the pilot whether all engine failure occurs according to the engine state, and then the return capability evaluation subsystem (200) screens the landing site according to the remaining energy of the aircraft for the pilot to make a final decision. The return stage decision-making subsystem (300) and the return instruction autonomous generation subsystem (400) automatically generate the aircraft control strategy and the state instructions that the pilot should track in real time according to the orientation and flight speed of the aircraft from the landing point, and then inform the pilot through the screen display, Assist the pilot to complete the emergency landing mission when all engines fail.

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...

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
