Hold-down and release mechanisms, hinges, dampers and deployment springs for arrays, antennas and booms.
What decides the purchase: Release shock · preload · deployment torque · actuation type (pyro, SMA, burn wire)
Typical materials: Titanium, stainless, shape-memory alloy
What changes when it has to fly: Single-shot and unrecoverable. Qualification is by test, and low-shock non-pyro release is increasingly preferred.
