TiNi AEROSPACE'S Frangibolt family of actuators is designed for deployment of a wide variety of stowed appendages including solar panels, antennae, cover doors, and various experimental payloads. The principle of operation is simple: a Shape Memory Alloy (SMA) cylinder elongates to fracture a bolt element thereby achieving separation of two or more components. The Frangibolt actuator comprises of a cylinder of Nitinol (Nickel-Titanium) SMA and a specially designed (integrated) heater. The family of actuators shown are designed to release loads up to 5,000 lbf. Flight Qualified Since its outer space debut aboard the spacecraft Clementine (1994), the Frangibolt has been qualified and used on numerous other space applications. Safe to Handle and Operate The Frangibolt emits significantly less shock than comparable explosive devices and as a result requires no special handling and safety precautions. Simple to Use The actuator is simply incorporated in the releasable joint using the specially notched fastener and pre-loaded to the prescribed torque. Re-Usable & Reliable The actuator may be used numerous times during acceptance and system level testing. Redundant Each Frangibolt incorporates a redundant heater which is capable of independently functioning the actuator. Reduced Cost Due to its relative simplicity, TiNi Aerospace is able to provide the Frangibolt at a significantly lower price than comparable devices.
