CubeHDRM - Hold-Down and Release Mechanism for CubeSats

CubeHDRM is a miniature Hold-Down and Release Mechanism (HDRM) is designed to secure deployable components such as solar panels, antennas, or booms during launch and to release them upon command once in orbit.

A compact and lightweight form factor has been adopted to meet the constraints of CubeSats and other small satellite platforms. Release is accomplished through the controlled disengagement of a preloaded nut, allowing stored energy from hinge or deployment springs to actuate the mechanism.
