FIELD: aircraft strength testing.
SUBSTANCE: invention relates to strength testing of aircraft. The safety device contains a membrane assembly, which is made in the form of a flexible toroidal bellows (5), one base of which is hermetically connected to the gate (4) of the working valve, and the other to the cover (2). The seat (3) of the working valve is integral with the body (1) of the safety device. The space bounded by the cover (2), bellows (5) and shutter (4) is a bellows chamber. The area of the section of the bellows chamber parallel to the shutter is greater than the area of the shutter. The cover (2) and the body (1) of the safety device are rigidly interconnected by a connecting element.
EFFECT: invention makes it possible to release a large mass of air from the internal volume of the product under test in a short period of time when it exceeds a predetermined pressure level and, as a result, increase efficiency.
