Project Description

Flat H Redundant Frangible Joint Development

This project ties to the Evolvable Mars Campaign in the HAT category of 12.1.b in reference to lightweight efficient structures. Some separation systems involve mechanisms with excessive mass The frangible joint is the most mass efficient separation option, however, the only concept commercially available is only suitable for unmanned applications due to lack of redundancy. The “Flat H” provides redundancy and complies with Agency requirements established for human-rated flight. The TAB category would fall in the 12.2.1.6 section involving lightweight, reliable, and predictable structures. This project is a follow-on from the FY 2015 ICA Dual Tube Frangible Joint project.

The pyrotechnic “Flat H” dual tube frangible joint technology addresses those requirements and has the potential to significantly increase pyrotechnic separation system reliability on space vehicles while having minimal impact to overall system mass. This effort also supports NASA S&MA to continue design efforts on a redundant joint solution since NA will not approve zero fault tolerant pyrotechnic designs past EM-2.
