A device for testing the deployment of projectile wings under the condition of multi-angle high-speed rotation of projectile body

Abstract

The invention relates to a device for testing unfolding of missile wings under a multi-angle high-speed rotation condition of a missile body, in particular to research on the rotating characteristic of the missile body under different angles, and belongs to the field of experimental research design of a high-speed rotating platform. The device comprises a probe, a transmission rod, a pre-tightening spring, a straight sliding type potentiometer, a voltage acquirer, a fixed-value resistance, a power source, a shell, a shell cover and a limiting bolt. The angle and the rotating speed of the missile body in a flying state are simulated through the rotating table, and the device, for testing unfolding of the missile wings, installed in the rotating table represents whether the missile wings are completely unfolded and locked by conducting, amplifying and detecting the displacement of a fixing pin. The two ends of the missile body are fixed to be connected with a support through the rotating table, and it is guaranteed that the missile body can stably rotate under a high rotating speed. The straight sliding type potentiometer is adopted for the testing device, a displacement signal of the pin is linearly converted into an electric signal, and the testing result can better perform representation and display.

Description

technical field [0001] The invention relates to a device for testing the deployment of projectile wings under the condition of multi-angle high-speed rotation of projectile bodies, in particular to the research on the rotation characteristics of projectile bodies at different angles, and belongs to the field of experimental research and design of high-speed rotating platforms. Background technique [0002] Rotary missiles are a type of small missiles with simple system, low cost and high reliability. This type of missile was first adopted by most anti-tank missiles. With the development of missiles, especially tactical missiles, in the direction of miniaturization, automation, autonomy, and ammunition, many small air defense missiles, especially portable missiles, have gradually chosen rotary bombs. It is closed inside the projectile body, and the projectile wings are unfolded by the internal ejection device and locked and fixed by the pin after receiving the trigger signal....

AI Technical Summary

Problems solved by technology

[0003] There are often pin holes and fixed pins designed to lock and expand the wings at the root of the wing and the body, and the movement of the pin at the tail of the body is a small displacement in a narrow space, which is difficult to identify and test. Therefore, it cannot be directly characterized whether the pin is reliably fixed under the existing means, and the conduction and amplification of small displacements have become a means of characterization
