A hypervelocity impact (HVI) Whipple Shield and a method for shielding a wall from penetration by high velocity particle impacts where the Whipple Shield is comprised of spaced apart inner and outer metal sheets or walls with an intermediate cloth barrier arrangement comprised of ceramic cloth and high strength cloth which are interrelated by ballistic formulae.

Enhanced whipple shield

A rigid patch body for placing over and around a damaged portion (hole) of the external wall of a pressurized vessel, such as a space vehicle or habitat. The rigid patch body allows a person such as an astronaut to make temporary repairs to the pressurized vessel from the exterior of the vessel to enable more permanent repairs to be made from the interior of the vessel. The pressure wall patch of the present invention includes a floor surrounded by four side members. Each side member includes a threaded screw for anchoring the patch body to the external wall of the pressurized vessel and a recess in its lower surface for supporting an inflatable bladder for surrounding the damaged portion (hole) of the external wall to seal the area surrounding the damaged portion to allow the vessel to be repressurized. The floor of the rigid patch body supports a source of gas in communication with a gas supply valve and a gas supply gauge in communication with the gas supply valve and the inflatable bladder.

Pressure wall patch

A missile having a shaped charge warhead mounted therein for being canted or near a target to present the shaped charge warhead in an advantageous position for destroying the target.

High velocity canting shaped charge warhead

A missile which has a shaped charge warhead mounted therein in such a man that the shaped charge warhead is automatically pivoted or canted after launch of the missile to present a shaped charge warhead in an advantageous position for destroying a target.
