[0002] The multi-body separation test model has the problem of measuring the force of multiple bodies separately. For the double-body and one unsheathed projectile model, a three-bar balance is required to measure simultaneously. The force measurement of the unsheathed projectile model can be achieved by using the conventional method of measuring the built-in balance of the measuring body. However, for the cover, since the wall thickness of the cover itself is relatively thin, especially after being thrown away, the inside of the cover becomes the windward side, that is, the outside of the cover needs to be simulated, and the cover balance cannot be placed inside the cover, but can only be arranged outside the cover.

[0003] At present, there is an urgent need to develop a dedicated hypersonic wind tunnel double-canopy static canopy back support force measurement test device. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a hypersonic wind tunnel double-cover static shield-throwing back-support force measurement test device.
