AbstractNot Available Pyro-pulse compatible, non-explosive release devices will be developed for separation of satellites from launch vehicles for next generation of small spacecraft missions. Two design prototypes will be developed which utilize redundant shape memory actuators to provide both pyro-pulse compatibility, and multiple operation capability without refurbishment. Both designs will provide: Low-shock, non-explosive separation Pyro-pulse actuation: 3.5-5 amps, 5-28 volts Pre-load capability to 3000 lbf. Multiple release without refurbishment or replacement Simultaneous release capability: < 50 milisecond release time The first prototype, the Linear Separation Nut (LSN), will be a next generation of the Lockheed Martin Low-Force Nut, modified to be pyro-pulse responsive. It will provide active shock mitigation and electrically powered remote reset. The second prototype (developed in parallel), the Rotary Separation Nut (RSN), is based on a Starsys Research proof-of-principal device. This device will be a low-mass, small profile design. Prototypes of both devices will be designed, manufactured, and tested in Phase I. In Phase II, a full micro-satellite dispensing system, capable of releasing multiple satellites, will be designed and developed around the optimum release device from Phase I. This adaptable modular system will dispense individual micro-satellites from a variety of launch vehicle platforms.
