BALLISTIC BENCH FOR HIGH-SPEED THROW OF SOLID BODIES WHEN TESTING POWER PLANTS OF AIRCRAFTS Russian patent published in 2021 - IPC G01M7/08 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering and flight safety and can be used to investigate impact interaction of aircraft structural elements and its power plant with solid (foreign) objects and small birds. Proposed device comprises base, gun carriage with propellant plant, descent mechanism, balloon ramp, target environment, control unit and registration unit connected in series, control panel second output is connected with descent mechanism. At the same time on the base on one side a platform is installed, on which there is a gun carriage with a propellant installation, equipped with a movement mechanism along an axis perpendicular to the longitudinal axis of the gun carriage, and on the opposite side - an armored cabinet, in which the target environment is located. Platform and armored cabinet are equipped with mechanisms of their movement in vertical plane, at that third, fourth and fifth outputs of control panel are connected to inputs of mechanisms of movement of platform, carriage and armored case respectively. Armor cabinet contains a frame made in the form of rigid parallelepiped, one face of which is open, other faces are equipped with detachable walls with shutoff devices, at least in one of side walls there is a cutout, in which armored glass is installed, on the rear wall from the inside there is a bullet trap.

EFFECT: technical result consists in improvement of processability during testing of power plants, shorter time for preparation for shooting during series of tests, higher level of safety.
