The compositions such as separation chamber, separation block, it is possible to the quality launched by two-stage light gas gun is kept completely separate with its bullet torr at the bullet sheet of 1～10g,
But, when its big quality bullet (5～7kg) separation of the projectile seat launched for one-stage light-gas gun, there is problems in that
First, the guide chamber in " a kind of bullet separation of the projectile seat device " is with separation chamber only by threadeding, and both rely on support again
The diffluence room of plate and monitor body is fixed, and this connected mode can bear the shock loading of little quality bullet, but along with bullet quality
(about 500～700 times) are greatly improved, and the shock loading that bullet separation of the projectile seat device is subjected to necessarily is significantly increased so that a whole set of
Structural strength and the stability of bullet separation of the projectile seat device decline to a great extent, and then possibly cannot meet requirement.
Secondly, according to momentum theorem, the momentum of little quality bullet (1～10g) is less, bullet torr under reverse impact load effect
The most just can slow down separation.Experiment results proved, although separate block one in " a kind of bullet separation of the projectile seat device "
The horn mouth of end collapses rapidly after clashing into bullet torr, but its momentum provided is sufficient for the separation of the deceleration to little quality bullet torr.
And the momentum of big quality bullet (5～7kg) is significantly increased, it is achieved slowing down to it to separate needs higher momentum, i.e. need to improve anti-
To impact loading in the time of bullet torr, bell-mouth structure of air obviously can not meet requirement.
