Abstract

The invention provides a device and method for testing the expanding characteristic of an empennage based on an air cannon device. According to the scheme, an air cannon, an experimental simulation bomb, a recycling box and a high-speed camera are included. The experimental simulation bomb is arranged in the air cannon. A shooting camera of the high-speed camera is arranged on the flight track of the experimental simulation bomb. The recycling device is arranged at the bomb point of the experimental simulation bomb. An empennage device is arranged outside the experimental simulation bomb. According to the scheme, the air cannon is adopted for launching the experimental simulation bomb, the empennage expanding condition of the experimental simulation bomb in the flight process is recorded through the high-speed camera, and the expanding performance of the empennage of a rocket can be tested under the completely dynamic condition; and the expanding process of a missile in a flying state can be truly simulated, the expanding characteristic of the empennage can be effectively evaluated, and the risk of a missile flying experiment can be reduced.

Description

technical field [0001] The invention relates to the field of testing the deployment characteristics of a rocket empennage device, in particular to a testing device and a testing method based on an air cannon device for the deployment characteristics of an empennage. Background technique [0002] In order to miniaturize the missile launcher and facilitate transportation and storage, a large number of tactical missiles are launched in boxes (barrels). Folding wings can reduce the size of aircraft, facilitate storage, transportation and launch, thereby improving the tactical and technical performance of weapon systems, and have been widely used in modern aircraft. Under normal circumstances, the wings are adapted to the inner wall of the launch box (barrel) after being folded and folded, and stored in the launch box (barrel); after the missile is launched from the barrel, the wings are deployed and locked in place under the action of the driving force. Folding the wings can re...
