Embodiment 1

[0046] A decision-making and guidance method for an air-glide forced landing of a manned fixed-wing aircraft. If the airport is the center, the forced landing route is divided into a course adjustment section, a longitudinal plane glide section, a landing course adjustment section, and a landing longitudinal plane glide section, and each section corresponds to The horizontal flight distance is l 54 , l 43 , l 32 , l 21 , and the energy height corresponding to the loss is h 54 、h 43 、h 32 、h 21 ; The aircraft performs a balanced and stable hovering downward movement in the course adjustment section and the landing course adjustment section, and performs a balanced straight-line slide movement in the vertical plane glide section and the landing longitudinal plane glide section.

[0047] After the aircraft is idle, take the glide gauge speed corresponding to the best air-slip ratio and force-slide to the altitude required by the scheduled airport as the reference energy alt...

Embodiment 2

[0053] A manned fixed-wing aircraft air-skid forced landing decision-making and guidance method, such as Figure 9 As shown, the purpose is to help pilots or commanders make timely decisions on whether to make an emergency landing or not according to the flight status of the aircraft after air parking, so as to improve the success rate of emergency response after the aircraft stops in the air. The decision-making criterion is based on the equivalent energy height of the aircraft, and in order to achieve the above object, the technical scheme adopted in the present invention includes:

[0054] 1) The decision-making and guidance of the manned fixed-wing aircraft air-skiing emergency landing decision-making and guidance system are based on the optimal emergency landing route planning under the unpowered state of the aircraft.

[0055] 2) The manned fixed-wing aircraft air-skid forced landing decision-making and guidance system is divided into two major functional modules. They ...

Abstract

The invention discloses a decision-making and guiding method for air-sliding forced landing of a manned fixed-wing aircraft.The method comprises the steps: carrying out forced landing on an aircraft at an optimal forced landing route if the aircraft has the capability of air-sliding to a designated airport during parking; and if the aircraft does not have the capability of skating to the specified airport during parking, judging whether other airports capable of landing forcibly exist in the airport skating reachable domain range or not, if so, planning an optimal skating forced landing route and landing forcibly in the specified airport, and if not, selecting a parachuting point in the airport skating domain range. According to the invention, unpowered forced landing of the manned aircraft is guided from the angle of the effective residual energy height, the optimal forced landing route is rapidly obtained through the effective residual energy height, and operation is reliable and safe.

Description

technical field [0001] The invention belongs to the technical field of a forced landing system of a manned aircraft, and in particular relates to a decision-making and guidance method for an forced landing of a manned fixed-wing aircraft. Background technique [0002] The engine is the power source of the aircraft. It provides the required thrust or torque for the flight of the aircraft, and provides hydraulic pressure, bleed air and power supply for the aircraft through the transmission accessories, which is the key to ensure the normal flight of the aircraft. Once the engine stops in the air and fails to start in the air, the pilots and air traffic controllers are required to make a decision to parachute or air slide to a landing airport as soon as possible according to the current state of the aircraft, so as to ensure the safety of life and property to the greatest extent. [0003] At present, most of the domestic and foreign researches on unpowered return and forced lan...
