Active bird strike prevention method and device for aircraft

Abstract

An active type bird collision prevention method and device for aircraft; the method comprises: activating a radar detection device (1) to detect whether a flying creature such as a bird approaches a preset danger area of the aircraft, and transmitting a detected signal to a central controller (2) in an aircraft cockpit; after receiving the danger signal transmitted by the radar detection device (1), the central controller (2) activates a fuel gas generator (3) installed in the aircraft engine (11), or in the aircraft head or in the aircraft body to generate high-temperature high-pressure fuel gas; the fuel gas flow jetted by the fuel gas generator (3) strikes the body of the flying creature such as a bird to bounce the bird away from the aircraft, thus avoiding collision between the bird and the engine or the aircraft body. The device on the aircraft actively protects the aircraft, providing more thorough and more effective protection. In addition, the device can drive off large birds, thus solving the problem in the prior art of incapability of protecting against collisions with large birds.

Description

technical field [0001] The invention relates to bird strike prevention technology, in particular to an active bird strike prevention method and device for aircraft. At the same time, it is suitable for high-speed trains, helicopters, etc. Background technique [0002] Since the invention of airplanes, bird strikes have become one of the important factors threatening aviation safety. With the development of aviation technology, the speed of aircraft continues to increase, and the high-speed movement makes the destructive power of bird strikes reach an astonishing level. The light ones cause damage to the aircraft and cause property losses; the severe ones destroy the aircraft and cause major disasters. According to the statistics of the International Aviation Federation for many years, there are more than 10,000 bird strikes in the world every year. Bird strikes are the most important factor leading to flight accidents. The International Aviation Federation has upgraded bir...

AI Technical Summary

Problems solved by technology

However, the above two methods have the following problems: 1. Due to the limitation of material strength and other factors in reality, the strength of the fuselage material cannot be infinitely increased to the extent that it can resist the impact of all birds, and the larger the bird is in the actual flight. more aircraft losses

2. There is a blank area for bird repelling control, that is, there are areas that cannot be controlled by existing bird repelling methods. Many serious bird strike accidents occur at medium and high altitudes far away from the airport

That is to say, the bird repelling action cannot absolutely guarantee the result that the birds will be driven away from the target area
