Embodiment 1

[0048] Such as figure 1 As shown, a bird strike test device proposed by an embodiment of the present invention includes a pressure release mechanism 1 with an air outlet port 11, a gun barrel 2 with a birdshot mounting part inside, and a casing brake with a fixed flange 31. device 3. The barrel 2 has a first end 21 and a second end 22 opposite to each other. The first end 21 of the gun barrel 2 is connected to the air outlet end 11 of the pressure release mechanism 1, so that the inside of the air outlet end 11 communicates with the inside of the gun barrel 2, and the compressed air in the pressure release mechanism 1 can enter the gun barrel through the air outlet end 11. inside of barrel 2. The second end 22 of the gun barrel 2 is connected with the fixed flange 31 of the shell brake device 3, and the birdball enters the shell brake device 3 through the second end 22 of the gun barrel 2, and the shell of the birdball is caught by the shell brake device 3. Braking, the bod...

Embodiment 2

[0064] The specific structure of the bird strike test device in Embodiment 2 is basically the same as that of the device in Embodiment 1, the difference is that the first sealing film 41 of the bird strike test device in Embodiment 1 is directly sandwiched between the air outlet end 11 and the Between the first end 21 of the gun barrel 2 (such as figure 2 shown), and the bird strike test device in the second embodiment, such as Figure 7 As shown, it also includes a connecting pipe 7 through which the gas outlet port 11 is connected to the first end 21 of the barrel 2, and the aforementioned first sealing film 41 is sandwiched between the connecting pipe 7 and the first end of the barrel 2 Between 21. In the second embodiment, the connecting pipe 7 has a buffer function, which can reduce the reaction force of the pressure release mechanism 1 due to the resistance of the first sealing film 41 to the pressure release mechanism 1 when the pressure release mechanism 1 releases c...

Embodiment 3

[0068] The embodiment of the present invention also provides a bird strike test method, which is used in conjunction with a bird strike test device. Wherein, the bird strike test device includes a pressure release mechanism with an air outlet port, a gun barrel with a birdball mounting part inside and a shell braking device with a fixed flange, the gun barrel has opposite first ends and second ends, The first end is connected to the air outlet port, and the second end is connected to the fixed flange; the bird strike test device also includes a first sealing device and a second sealing device; the first sealing device includes a first sealing film, and the first sealing film is sandwiched Between the first end and the air outlet end; the second sealing device includes a second sealing film, and the second sealing film is sandwiched between the second end and the fixed flange; the barrel is between the first end and the second end The part of the barrel is provided with a decom...

Description

technical field [0001] The invention relates to the technical field of bird strike tests, in particular to a bird strike test device and a method thereof. Background technique [0002] A bird strike generally refers to a bird colliding with an airplane or a high-speed train in the air, causing an accident and causing a major safety hazard to the aviation aircraft and the high-speed train. With the rapid development of my country's aerospace industry and railway transportation industry, the requirements for the safety performance of aircraft and locomotives are getting higher and higher. Anti-bird strike test is an important method to evaluate the safety performance of aircraft and high-speed trains. [0003] Anti-bird strike performance is one of the important parameters to be considered in the aircraft design process. Usually, compressed air is used to accelerate bird bombs to simulate a bird hitting an aircraft to evaluate the bird impact resistance of aircraft structure...
