Abstract
The present invention is a projectile trap assembly for capturing projectiles emitted along a line substantially parallel to ground. The projectile trap assembly includes a support frame having an upper surface inclined relative to the line of the projectiles and a particulate flowable granulate material exhibiting an angle of repose. The particulate granulate material is supported by the support frame at the angle of repose, whereby the particulate granulate material receives and slows down the projectiles.
Claims23
A projectile trap assembly for capturing projectiles emitted along a line substantially parallel to ground, comprising:
- a support frame having an upper surface inclined relative to the line of the projectiles;
- a particulate flowable granulate material exhibiting an angle of repose, the particulate granulate material being supported by the support frame at the angle of repose, whereby the particulate granulate material receives and slows down the projectiles;
- and
- a self-healing member covering the particulate granulate material, whereby the projectiles penetrate the self-healing member in order to enter the particulate granulate material.
A projectile trap assembly for capturing projectiles emitted along a line substantially parallel to ground, comprising:
- a support frame having an upper surface inclined relative to the line of the projectiles, the upper surface being elevated with respect to the ground, and the elevation of the upper surface being adjustable;
- and
- a particulate flowable granulate material exhibiting an angle of repose, the particulate granulate material being supported by the support frame at the angle of repose, whereby the particulate granulate material receives and slows down the projectiles.
A projectile trap for capturing projectiles emitted along a line substantially parallel to ground, comprising:
- a support structure including a support surface;
- a flowable particulate rubber material being disposed on the support surface, whereby the particulate rubber material receives and slows down the projectiles;
- and
- an anti-adhesion material interspersed between the particulate rubber material, whereby the anti-adhesion material prevents adhesion of the particulate rubber material in the presence of heat generated by the received projectiles.
