New Russian aircraft engine is safe from large birds
Bird Strike Resistance is an official term in aircraft construction. Collision with a bird is potentially a very dangerous event for an airplanes and other aircrafts, so the windshields, fuselage and engines of an aircraft are designed in such a way that the collision could not cause damage to the aircraft.
Carcasses of real birds are used in experiments for the bird strike capability. Sergei Petrov, the head of the experimental research department of the Institute has explained that for an engine of about half a meter in diameter a small bird is needed, about 0.9 kg in weight. And if the engine is a large one (3.25 meters in diameter), then a goose weighing about 3.6 kg is used.
The test involving throwing of a bird was successful, said a source at the Central Institute of Aviation Motors named after P.I. Baranov.
