A projectile for a liquid propellant gun comprising a metallic forward end nd a shock buffer aft end made up of from about 60 to about 40 volume percent microballoons and from about 40 to about 60 volume percent binder.

Shock buffer for liquid propellant gun projectile

A method for molding one piece seamless contoured structures. The mold consists of a hollow, cylindrical mold member whose internal surface area defines the external surface of the piece to be molded, that is adaptive to receive a piston having a reservoir containing a fluid plastic and a mandrel mold member of low melting alloy whose shape defines the internal surface of the molded structure. The piston is forced upward to cause the fluid plastic to flow into the interstices and allowed to cure. Heat is applied to the mold assembly to melt the alloy to allow removal of the contoured structure when the mold assembly is disassembled.

Process for fabricating one-piece rocket motor heat barrier

An improved tow line and attachment apparatus for use with a rocket motor ilized in carrying a line, towing a load or extracting an aircrew member from a disabled aircraft. The tow or pendant line is attached to the rear end of a rocket motor adjacent its nozzles and sustains the load to be carried during powered flight. Flame and heat exiting from the nozzles during powered flight from the burning propellant can impinge a pendant line attached adjacent the nozzles. To prevent weakening or destruction of this portion of the tow line a silicone rubber envelope is fabricated around the line.
