Summary of the invention:
The objective of the invention is for solve existing stretched shape bullet deposit the separating effect instability, increase the problem of launch cost, a kind of curve shaped bullet holder in autosegregation is provided.The present invention has under the condition that keeps target cabin vacuum, does not increase any device the bullet holder is separated with bullet, improves emission effciency, reduces the characteristics of launch cost.The present invention is made up of left split 1 and right split 2; The horizontal cross-section of left split 1 and right split 2 is two corresponding semicircles, the top of inner face 11 1 sides of left split 1 has left half bullet hole 3, the inner face 11 of left split 1 is provided with left profile of tooth body 5, the top of inner face 12 1 sides of right split 2 has right half bullet hole 4, half bullet hole 3, a left side on the left split 1 is corresponding with the half bullet hole 4, the right side on the right split 2, the inner face 12 of right split 2 is provided with the right tooth shape body 6 that is meshed with left profile of tooth body 5 on the left split 1, left split 1 is a curve shaped 9, and right split 2 is curve shapeds 10 symmetrical with left split 1.The present invention is designed to the holder of bent body bullet with the holder of existing stretched bullet.After bent body bullet support was gone into the transmitting tube of high speed light-gas gun, being subjected to the restrained deformation of transmitting tube tube wall was stretched, and remained stretched move along launcher-tube line in transmitting tube in emission process.At the moment tube wall that breaks away from the transmitting tube mouth of pipe constraint of bullet holder is disappeared, bullet holder meeting reverts to bent body, and the bullet holder can produce in reverting to the process of bent body along perpendicular to the moving of launcher-tube line direction, thereby, bullet holder and bullet are separated.Just be equivalent to add between the bullet holder spring that the bullet holder is separated, only this spring is exactly bullet holder itself.Under the gas effect after the bullet holder separately in transmitting tube, can rotate, proal speed is reduced, further improve separating effect around barycenter.The present invention has under the condition that keeps target cabin vacuum, does not increase any device the bullet holder is separated with bullet, improves emission effciency, reduces the advantage of launch cost.
