Abstract
Penetration apparatus, for very high temperature applications in which a base plug (12) is inserted into an opening through a bulkhead (11), the base plug (12) having a head shape (14b) seating against the highest temperature surface (11a) of the bulkhead, which may be the skin of the nose cone or other part of a space vehicle intended for nondestructive atmospheric reentry. From the second side of the bulkhead (11b) at which the less severe environment is extant, a bayonet plug (14) is inserted into the base plug and engages an internal shoulder (19) therein upon 90.degree. rotation. The bayonet plug (14) has an integral flanged portion (14a) and a pair of ramping washers (16 and 17) are located between the flange (14a) and the second bulkhead surface (11b) with a spacing washer (15) as necessary. Rotation of one ramping washer with respect to the other provides an axial tensile force between the bayonet plug (14) and the base plug (12) to lock the assembly in place without the use of threads or other easily oxidized shapes. Columbia base metal is employed with silicide coating, and provision is made for safety wiring (20) of the ramping washers (16 and 17) against unintended rota…
