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...

Embodiment Construction

[0016] The magnet base 1 is in the shape of a disc, with a vertically upward cylindrical protrusion at the center of the upper part. The bottom of the magnet base 1 near the edge has a circular step-shaped groove, and the magnet 2 is installed in the bottom groove. The magnet sealing cover 3 The magnet 2 is fixed by threaded connection with the circular groove of the magnet base 1 , and the outer surface of the magnet sealing cover 3 is flush with the bottom surface of the magnet base 1 .

[0017] The recorder circuit board 6 is in the shape of an annular sheet, along which an accelerometer 9, a memory 10, a processor 11, an antistatic chip 12, a power chip 13, a recoil switch 14, and a battery 15 are arranged, and the detector 5 is welded on On the recorder circuit board 6.

[0018] The recorder base 8 is cylindrical, and the upper center part has a cylindrical groove with an upward opening. The recorder circuit board 6 is placed in the groove, and its outer diameter is close...
