Dual Pulse Motor advanced bulkhead

Advanced future missions have specified pulse motor requirements to include initial boost thrust, a variable coast time up to 120 sec, and a second boost “end game” thrust. The industry has been successful in demonstrating dual pulse systems with limited interpulse coasting, typcally < 50 sec, using a soft barrier pulse technology. The long interpulse coast, however, has historically been the “Achilles heel” using the a soft barrier pulse techniques where unreliable pre-mature second pulse ignitions have occureed. To successfully meet long interpulse missions Valley Tech Systems is proposing developement of an innovative dual chamber bulkhead design that enables a unique dual chamber motor system. Results will be a pulse motor design that delivers desired performance while exhibiting first and second pulse ignition reliability while providing the long inter pulse coast.
