Active type bird strike prevention method and device for aircraft

Abstract

The invention relates to an active type bird strike prevention method and device for an aircraft. The method comprises the steps that in the flying process of the aircraft, a radar detection device is started to detect whether birds and other flying animals approach preset dangerous areas of the aircraft and transmits a detected signal to a central controller in a cockpit of the aircraft; the central controller starts a fuel gas generator after receiving the danger signal transmitted by the radar detection device, so that the fuel gas generator produces high-temperature and high-pressure fuel gas, wherein the fuel gas generator is installed on an aircraft engine or a nose or a fuselage; fuel gas flow is ejected out of the fuel gas generator and then strikes on and bounces off the bodies of the birds and other flying animals, so that the birds and other flying animals fly away from the fuselage of the aircraft along with the gas flow and are prevented from colliding with the engine or the fuselage. The protection for the aircraft belongs to an active protection behavior and is complete and more effective. In addition, the active type bird strike prevention method and device can expel large birds, solve the problem that a collision by the large birds cannot be prevented in the prior art and allow the aircraft to be safer and more reliable in the flying process.

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...

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
