User-friendly, high-performance release device triggering any space mechanism on-orbit.
The Dcubed Micro Release Nut (uD3RN) is a Shape Memory Alloy (SMA) based release actuator which locks sensitive equipment during launch and safely releases it on orbit. It is one of the smallest, yet powerful Hold-Down and Release Mechanism (HDRM) solutions on the market. Moreover, it is easily resettable (on-ground, in space), easy-to-use and readily available as a COTS part.
