Abstract

The invention discloses an instant automatic releasing device and belongs to testing devices of the technical field of helicopter dynamics. The instant automatic releasing device is used for achieving the instant automatic releasing function when an anti-crashing test is carried out on a whole helicopter or components of the helicopter. The instant automatic releasing device comprises a bearing frame, an electromagnet, a connecting rod mechanism, a claw hook and a movable plate. The movable plate is of a strip-shaped structure and arranged between two hook-type pieces in the claw hook. Gears on the two sides of the movable plate are meshed with gear discs in the two hook-type pieces of the claw hook. When the claw hook is in an opened state, the movable plate can be pushed and triggered to enable the claw hook to be closed automatically. When the claw hook is in a closed state, the electromagnet is powered on and triggered, and the claw hook is made to be in an opened state through the connecting rod mechanism. The instant automatic releasing device achieves the automatic releasing function of a tested piece in the anti-crashing test of the whole helicopter or the components of the helicopter, and test risks are lowered. The instant automatic releasing device has the advantages of being high in control precision, high in bearing capacity, stable and reliable in operation and the like, and hook opening operation and hook closing operation are smooth and stable.

Description

technical field [0001] The invention belongs to a test device in the technical field of helicopter dynamics, and is applied to the instant automatic release of the anti-crash test of the whole helicopter or components. Background technique [0002] Helicopter anti-crash technology is one of the five key technologies in the development of helicopters, and the anti-crash test is an important means to verify this technology. The anti-crash test technology of helicopter whole machine and parts is a new technology field in our country. In the test, the vertical speed of the simulated helicopter crash is converted from the launch height. The anti-crash test is a high-risk test item, which is not repeatable. Each test system requires high stability and reliability. . The instant release technology is one of the key technologies in the helicopter anti-crash test. According to different test requirements, the instant release has different load carrying capacity, reliable performanc...
