Abstract

The invention provides a relative rotation speed determination device. The elative rotation speed determination device comprises magnetic steel which is disposed on a housing of a projectile body of an aircraft, is used for generating a magnetic field, and carries out the first coaxial rotation with the projectile body according to a first speed; a magnetoresistive sensor which is connected with the magnetic steel and the data processing module, and is used for acquiring rotating speed data of a magnetic field generated by the magnetic steel, which is changed along with the first coaxial rotation, and sending the rotating speed data to the data processing module; and a data processing module which is used for determining the relative rotating speed between the stern of the aircraft and the projectile body according to the rotating speed data. By the adoption of the technical scheme, the problems that in the related technology, a device for determining the relative rotating speed between the two parts of equipment is large in installation occupied space and cannot adapt to large overload are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a device for determining a relative rotational speed. Background technique [0002] With the continuous improvement of high-rotation guided projectiles and projectile guidance requirements, low-cost precision strikes have become the development direction of army weapons and equipment in various countries. Among them, the relative rotational speed measurement technology and device of the missile play an important role in the accurate measurement of the rotational speed of the military shell, the record of the motion state of the projectile, the real-time correction of the ballistic trajectory, precise guidance and flight stability control. In addition, the direct measurement of the relative speed can make the control system respond faster, and provide data support for the optimization of the projectile structure and control system. In order to meet the requirements of high over...
