Abstract

The invention discloses a ballistic parameter-recording device. The device mainly comprises a magnet base (1), a magnet (2), a magnet-sealing cover (3), a recorder-sealing cover (4), a detector (5), a recorder circuit board (6), filler (7) and a recorder base (8). In the flying process of a shell, the recorder base (8) is kept fixed relatively at the position of the shell body, the magnet base (1) is driven by a rigid empennage to rotate, a high level-low level-high level jump process can take place each time when the magnet (2) passes the detector, the generated jump can be recorded by the recorder circuit board (6), at the same time, an accelerometer (9) starts to work, and the frequency and acceleration of the jump process within a certain period of time are recorded by a memory (10) in real time. The device can be widely applied, and can simultaneously record the flying time of the shell, the relative rotational speed of the shell and the empennage and the overload parameter in the flying process of the shell.

Description

technical field [0001] The invention relates to a ballistic parameter recording device. In particular, it relates to a device for recording the flight time of the ballistic trajectory, the relative rotation process of the missile body and the rigid tail, and the overload parameters of the missile body during the flight. Background technique [0002] Over the years, researchers at home and abroad have invested a lot of energy in the research of projectile rotational speed testing. So far, the commonly used methods for measuring the rotational speed of projectiles mainly include the following: centrifugal acceleration measurement method, photoelectric conversion method, geomagnetic azimuth transformation method, Doppler radar measurement method, mechanical measurement method, paper target method, photogrammetry method, Telemetry and radio fuze measurements. [0003] Storage test technology is a technology developed in recent years, and it is an effective means to complete th...
