INERTIA APPARATUS FOR STOPPING HOLDER BLOCK WHEN TESTING AIRCRAFT FOR RESISTANCE TO BIRD STRIKES Russian patent published in 2012 - IPC G01M7/08 

FIELD: physics.

SUBSTANCE: apparatus has a support with a centre hole and a buffer, wherein the support lies at a calculated distance from the section of an air gun barrel and is rigidly mounted on guide axes mounted at the end of the barrel of the air gun. Brake plates are freely mounted on the guide axes at a calculated distance from each other and have centre holes which are in line with the barrel of the air gun. The number and weight of the brake plates is selected in accordance with the speed and weight of the holder block and the bird. The diameter of the centre hole of the first plate is 10±1 mm smaller than the outer diameter of the holder block, and the diameter of the centre holes of the next plates and the support is 20±1 mm larger than the inner diameter of the holder block.

EFFECT: design of apparatus which enables to keep the holder block intact after a sufficiently large number of strikes, broaden functional capabilities of the air gun, cut the time spent preparing to shoot and make manufacturing of the apparatus and holder block easier.
