TiNi’s Frangibolt actuators are a simple and effective way to support and release loads up to 20,000 lbf. The principle of operation is simple: A Shape Memory Alloy (SMA) cylinder elongates to fracture a bolt or stud thereby achieving separation of two or more components. Standard Fastener sizes range from # 8 size screws to ¾” bolts.
TiNi FRANGIBOLTs OFFER THE FOLLOWING ADVANTAGES:
Significant Flight Pedigree – Since its outer space debut aboard the spacecraft Clementine (1994), the Frangibolt has been qualified and used in numerous other space applications.
NEA (Non-Explosive Actuators) – As with all TiNi products, the Frangibolt is non-pyrotechnic and field reset-able with a minimum qualified life of 60 cycles.
Easy to Reset & Simple to Use – The actuator is reset by the customer in a matter of seconds (i.e. no need to ship back to TiNi). This enables numerous system level testing to be performed prior to flight usage to ensure maximum reliability.
Redundant – Each Frangibolt incorporates a redundant heater which is capable of independently functioning the actuator.
Safe to Use and Operate – The Frangibolt does not pose any safety concerns to personnel, is low shock, and insensitive to ESD (Electro-Static Discharge).
Cost Efficient – Due to its relative simplicity, TiNi Aerospace is able to provide the Frangibolt at a significantly lower price than comparable devices.
