Actuator
FC3-20-16SR2
The FC3-20-16SR2 Frangibolt Actuator was first qualified and flown on the STEX (Space Technology Experiment) satellite in October of 1998. It is designed to operate with any standard high strength #10 size notched bolt or stud1. The Nitinol (Shape Memory Alloy) cylinder generates greater than 2000 lbs of force and 0.035 in. of stroke to fracture the fastener in tension during actuation. As with all Frangibolt Actuators it is reloaded by simply re-compressing the Nitinol cylinder after each actuation cycle. This may be done using any standard laboratory press or using TiNi's portable compression tool FBT-CT2. Frangibolt model FC3-20-16SR2 may be purchased with a thermocouple by adding a TC to the part number.

TiNi Aerospace must provide the specially notched Titanium Fastener.
This is largely application-dependent and is readily manufactured to
customer specification. See Frangibolt Fastener
