Here's a paper that was presented at the 2014 Small Satellites Systems and Services Symposium. Thanks to Rik ISS-fan for pointing this out in another thread.http://congrexprojects.com/2014-events/4S2014/proceedings
Nammo reported on it website that they have succesfully test fired the Flight Weight Unitary Motor 1 (FWUM)
"The most important thing now is that that we have proven in full scale that we can stop and restart the motor multiple times during a firing and it worked optimally in this test" Onno Verbene -- Director of Spaceflight for Nammo
The Bloodhound SSC supersonic car is to use Nammo HTP/HTPB hybrid motors, presumably related to this project.
