ABSTRACT:
The reliability of electronic navigational equipment, such as missile guice sets, frequently requires a precisely-aligned support or mounting which must be rigidly maintained during the missile operation or flight. To maintain the alignment, the housing for the electronics is rigidly supported by a link mechanism pivotally coupled at one end to the missile airframe and, at the other, to the electronic housing through a crosshead assembly which includes a crosshead block slidably mounted in dove-tailed tracks of a crosshead guide carried by the housing. A spring-urged plunger of the crosshead assembly has its ends engaged in steep-walled detents to normally, during flight, lock the block in a fixed position. Extreme, non-operational, acceleration forces such as otherwise would damage the electronics, overcome the spring force on the plunger permitting a slidable breakaway displacement. Resilient shock absorbers then protectively cushion the force. The absorbers also function to subsequently return the block to its locked position and realign the structure. The detent profile includes a shallow-angle peripheral ramp to facilitate realignmemt.
