Micro Electro-mechanical Systems (MEMS) Safe & Arm for Rocket Motor Ignition

Ignition of rocket motors can be performed using low-volt firing components, but MIL-STD-1901A requires mechanical isolation for safety. While traditional safe & arm devices are available, they are relatively large and heavy. Recent progress in MEMS has developed miniature safe & arm devices for low-cost munitions such as 40MM grenade and airburst munitions. The Black Hills Nanosystems team has developed a low-cost silicon-based safe & arm solution based on commercial manufacturing processes. The technology is relative mature, and safe & arm devices have demonstrated survivability in high-g acceleration gun launches. The proposed SBIR Phase I project aims to adapt the MEMS safe & arm technology for rocket motor applications. Approved for Public Release 14-MDA-8047 (14 Nov 14)
