Joint for mounting components on a rocket

Abstract

A joint for mounting a component on a rocket, such as mounting a valve to a rocket body. The joint comprises a coiled roll pin and a shaft. The coiled roll pin comprises a rolled sheet defining an internal channel. The shaft extends through the internal channel and extends out both ends of the coiled roll pin. At each end of the shaft is disposed one or more compressible disc springs. Retaining rings or flat washers may compress the disc springs for axial restraint. The ends of the shaft may include a cover with an outer diameter larger than a joint hole. The joint compensates for vibrational loads, for example due to launch, and for dimensional changes, for example due to temperature gradients between two parts being connected by the joint. Some embodiments include no shaft, with the coiled roll pin axially secured by a cover or cover plate.
