Problems solved by technology

This method mainly has the following defects: the process is complicated; under normal circumstances, the counterweight is assembled first, and the weight is increased after the counterweight is completed, which is not convenient for assembly between cabins; hard to get the counterweight out
[0005] 1. The cabin and the counterweight are designed as an integrated structure, which increases the difficulty of manufacturing the cabin;
[0006] 2. When the lead block is embedded, the calculation workload is heavy, and the configuration is complicated and difficult;
[0007] 3. The lead block is embedded in the hole. When it is solidified with the hole, it is difficult to take out the lead block; stability

Abstract

The invention provides a guided missile mass and mass center adjusting device and method. The guided missile mass and mass center adjusting device comprises balance weight pipes (2, 3) located in a guided missile bin (1), a plurality of clump weights (4) placed in the balance weight pipes (2, 3), and end caps (5, 7, 8, 9) detachably connected with the two ends of the balance weight pipes (2, 3) correspondingly; and the balance weight pipes (2, 3) are connected with the guided missile bin through flange plates (6, 10, 11). During assembling of the guided missile mass and mass center adjusting device, firstly, the end caps at one end are connected with a bin body or one flange plate (10), and then one ends of the balance weight pipes are connected with the end caps; then the other ends of the balance weight pipes are fixed through the other flange plates (6, 11), the end caps at the other ends of the balance weight pipes are assembled, and the bin body without balance weight is assembled; and after installing and debugging of equipment in the bin are completed, the initial values of the mass and the mass center of a guided missile are measured, the balance weight scheme is formulatedthrough comparison with the theoretic mass and mass center, and accurate adjusting on the mass and the mass center is achieved.

Description

technical field [0001] The invention relates to the technical field of missiles, in particular to a device for adjusting the center of mass of a missile; the invention also relates to a method for adjusting the center of mass of a missile. Background technique [0002] The mass of the missile needs to be adjusted through the counterweight, and at the same time, the relative position of the center of mass and the aerodynamic pressure center should be adjusted to improve the stability and maneuverability of the missile. The traditional adjustment method mechanically connects the counterweight to the cabin body through bolts and screws. This method needs to reserve an operating space for the installation of the counterweight, and the space utilization rate is low, and the adjustment efficiency of the center of mass is poor. Also have the method of " pouring lead " in the prior art, according to design, mold is cast earlier, then molten liquid lead water is poured in the mould. ...
