We are in Obninsk, Russia, to see how they test aircraft and locomotive glazing there for resistance to bird strikes and other impacts.
This is the glazing of Ka-62 helicopter.
And this system is for test shooting. It is mounted on an anti-aircraft gun carriage made in 1954.
Gun length – twelve meters.
The system itself was made in 1971 in Kasnoznamensk, Russia.
Pneumatic launching device Pu-132.
The gun is powered by air and shoots with compressed air.
Two air receivers from a submarine are used. They can provide pressure of 400 atms, but are certified for 30 atms, which is enough to achieve a speed of about 1200 -1300 km/h.
The inner diameter of the barrel is 132 mm, the shell mass – up to 2 kg.
The mass of our test “bird” is one kilogram, its speed – 270km/h.
After being shot.
The test has been passed successfully, the window is neither cracked nor broken.
The glazing is considered bird-impact resistant because it has no reach-through breakdown (pilot should not suffer). The helicopter itself should be able to further fly for at least two hours. And it will until it runs out of fuel.
Such glazing will be used for a number of Russian helicopters in the near future.
