Abstract
A rupturable bag assembly comprises an inflatable bag which parts at a target internal pressure to produce an acoustic shock wave having a minimum target noise level at a prescribed distance. The inflatable bag comprises inner and outer walls. The inner wall has greater elasticity than the outer wall. Both inner and outer walls are constructed from first and second disk shaped sections with the first and second sections being sealed along outside perimeters. The second section of the inner wall carriers a heat resistant shield on one face. An inflation port assembly provides a chamber for a fuel source and flame abatement elements between the fuel source and an inlet port to the rupturable bag.
Claims11
A rupturable bag assembly for a stun grenade comprising:
- a bag having inner and outer walls;
- the inner and outer walls each having first and second opposed sections;
- the first and second sections of the inner wall being joined along a perimeter seam to form an inflatable balloon;
- the first and second opposed sections of the outer wall being joined along a second perimeter seam;
- and
- the second perimeter seam being constructed to abruptly part at a target tension upon inflation of the inflatable balloon so that the inflatable balloon fails and an acoustic shock wave having a minimum target noise level at a prescribed distance results.
A rupturable bag assembly comprising:
- a balloon fabricated from an elastic material;
- an outer wall disposed around the ballon, the outer wall having a perimeter seam which parts abruptly at a minimum tension;
- an inlet port through the outer wall into the balloon for inflating the balloon to produce the minimum tension;
- and
- the outer wall being constructed of a relatively inelastic material in comparison to the material used to construct the balloon.
