A passive, multi-axis, highly damped, shock load isolation mount which can serve as a complete one-piece mount, particularly of a spacecraft to its launch vehicle or launch vehicle adaptor structure, or can serve in multiplicity as necessary to provide a complete shock load isolation mounting system

A passive, multi-axis, highly damped, shock load isolation mount which can serve as a complete one-piece mount, particularly of a spacecraft to its launch vehicle or launch vehicle adaptor structure, or can serve in multiplicity as necessary to provide a complete shock load isolation mounting system. When used as a one-piece mount or used in multitude as a system, the invention provides substantial reduction in the shock load transmission to a payload from its support base for both axial loads and lateral loads. The unique multi-layered, opposed beam, contorted load path flexure design combined with a shear wall type constrained layer damping treatment provides substantial shock load isolation in a durable, reliable, lightweight, and compact form.
