Abstract
Positive rocket motor pressure hull venting in the case of deck fires is vided by placement of thermite masses at spaced locations on the interior of the hull. Small cylindrical masses as well as strip formed masses are employed. The thermite mass includes a small amount of structurally formed aluminum as well as the conventional powdered aluminum.
Claims18
A pressure hull penetrator for rocket motors comprising:
- a rocket motor have a pressure hull with inner and outer surfaces;
- a mass of thermite material having a predetermined shape to conform to a selected area of the inner surface of said rocket motor pressure hull;
- an igniter compound in contact with said mass of thermite material and said inner surface;
- and
- a layer of insulating material overlying said mass of thermite material, said igniter mix, and adhering to said inner surface.

A pressure hull penetrator for rocket motor comprising:
- a rocket motor having a pressure hull having inner and outer surfaces;
- a plurality of thermite measses positioned within said pressure hull at predetermined locations adjacent said inner surface thereof and in physical contact therewith;
- a plurality of masses of igniter mix positioned in contact with the inner surface of said pressure hull and located in a predetermined pattern spaced about and in contact with said plurality of thermite masses;
- and
- a layer of insulating material bonded to said inner surface of said pressure hull and overlying said masses of igniter mix and said thermite mix.
