Shape Memory Alloy Isolation Valves: Public Quad Chart

Abstract

Existing propellant isolation systems such as pyrotechnic valves require special handling and have lifetimes (<10 yrs)shorter than typical operational spacecraft (15+ yrs).Shaped memory alloy isolation valves provide an intrinsically safe isolation system that increases lifetime>5x over SOTA and contain no explosives. Long lived propellant isolation systems are required to passivate spacecraft propulsion at end of life (>15 yrs) to prevent orbital debris and comply with treaty obligations. Reduced logistics requirements and intrinsically safe systems will produce industry wide savings.
