NASA is advancing inflatable aerodynamic decelerators (IAD) to deliver payloads to Mars, Venus, and Titan, as well as payload return to Earth from low Earth orbit. Current IAD gas inflation technologies are typically high pressure stored cold gas architectures. These systems are large, bulky, and have life-cycle downsides such as inherent shipping complications, deployment reliability, and safety concerns. To address these deficiencies Valley Tech Systems has developed a comprehensive IAD mission scalable solid propellant proportional gas generator system design that applies our new DOD and NASA SBIR developed lightweight long duration hot gas valve technology. During this Phase I SBIR we are proposing continuing of our technology development to better meet the IAD mission with a new miniaturized rotational valve architecture. The resulting SBIR development technology will reduce System Weight and Power (SWaP) by 2x while capable of scaling across all future NASA and commercial applications. The phase I program will conduct technology trades, engineering design and analyses, life cycle risk planning with a hot fire demonstration of the new rotational hot gas valve materials and manufacturing technology.
