Problems solved by technology

The force measurement of the shell-less projectile model can be realized by the conventional method of measuring body built-in balance, but for the cover body, because the wall thickness of the cover body itself is relatively thin, especially after being thrown away, the inside of the cover body becomes the windward side, that is, Both the inside and outside of the cover need shape simulation, and the cover balance cannot be placed inside the cover, but can only be placed outside the cover

Embodiment 1

[0081] Figure 6a ~ Figure 6e The installation process of the hypersonic wind tunnel double-shield static throwing shroud back support dynamometer test device of the present invention is given, and the details are as follows:

[0082] Such as Figure 6a As shown, the projectile model 1 is arranged from back to front and from inside to outside according to the tail strut 101, projectile balance 102, projectile rear section 103, projectile middle section 104, projectile front section 105 and projectile head 106. installed in sequence.

[0083] Install the tail support rod 101 first, and then install the elastic body balance 102. The rear end of the elastic body balance 102 is connected with the tail support rod 101 flange, and the flange adopts 2 pins for positioning and 6 screws for connection. The power line and data line of the elastic body balance 102 pass through the inside of the tail support rod 101 from the rear of the flange, and then pass through the bottom of the ta...

Abstract

The invention discloses a hypersonic wind tunnel double-cover-body static cover throwing back support force measurement test device. The device comprises a projectile body model, and two half cover body models, two sets of half cover angle adjusting devices and two sets of Y-direction interstage distance adjusting devices which are symmetrically distributed above and below the projectile body model. According to the hypersonic wind tunnel double-cover-body static cover throwing back support force measurement test device and the Y-direction stage spacing adjustment device, an integrated designis adopted, a semi-cover body balance is arranged in the internal space of the semi-cover angle adjusting device, the supporting and protecting problems of the half-cover balance are solved, the rigidity and strength of the device are improved, supporting components are reduced, static force measurement of separation of the hypersonic wind tunnel double-cover body and the projectile body is achieved, and adjustment of the half-cover angle of the half-cover model and adjustment of the distance between the projectile body model and the half-cover model are achieved.

Description

technical field [0001] The invention belongs to the technical field of hypersonic wind tunnel tests, and in particular relates to a static throwing cover back brace force measuring device with double covers in a hypersonic wind tunnel. Background technique [0002] There is a problem of multi-body independent force measurement in the multi-shroud throwing shroud separation test model. For the double shroud and one shroudless shroud model, three balances are needed to realize the measurement at the same time. The force measurement of the projectile model without cover can be realized by using the conventional method of measuring body built-in balance, but for the cover body, because the wall thickness of the cover body itself is relatively thin, especially after being thrown away, the inside of the cover body becomes the windward side, that is, Both the inside and outside of the cover need shape simulation, and the cover balance cannot be placed inside the cover, but can only...
