Video Caption: 9 second test burn of Hybrid Motor 7 – Heavy. This is the first burn with enough thrust to launch safely, as well as our most stable burn.
Video Cation: Test fire of Cal Poly Space System’s experimental rocket engine, Hybrid Motor 7 – Heavy. The test occurred on January 20, 2018, in the Cal Poly Propulsion Laboratory.
The teams update on the firing can be found here.

The second term of 2016-17 academic year has started and CPSS has some good progress to show. We are well on track for #ESRA 2017 Spaceport America Cup in June.
Avionics team has developed recovery board, manufactured hardware for the active guidance system, and well on the way to perform flight test in next 7 weeks.
Recovery team has completed separator device, which is going to be flight tested with Avionics. They are also about to finish design of the parachute, materials for which will be purchased in upcoming week.
Ground Support has completed new design for the system, as well as purchased required components. GS-Rocket interface has been redesigned as well, implementation of new quick disconnects is under way.
System Integration team has been focused on developing a new technique for manufacturing and attaching the fins that will not interfere with the integration of the propulsion system. New design employs honeycomb composite structure. The manufacturing of test fins took place over last weekend. The fins were tested last Friday (January 20th) for strength to assist the Recovery Team in determining parachute size an allowable impact velocity. A similar honeycomb design will be used for the bulkhead to support the loads from the parachute, and the centering rings for the N2 tank and parachute tubes.
Propulsion team has manufactured all major components of HM-7 Heavy over Christmas Break. Nitrous tank and combustion chamber are ready for hydrostatic test. Nozzle and injector are ready for test fire. All active plumbing components have been purchased and have arrived. Rest of the plumbing has been purchased as well. With a major setback of the timeline due to issues with hydrostatic test procedures approval, team has to delay short duration test fire by time unknown at the moment. Even with the setback, propulsion is still on track for launch in June.
CPSS is looking forward to upcoming testing. We have done a lot of manufacturing in past three month and we are looking forward to test every component of the system in next 12 weeks.
A nice video from Cal Poly Space Systems, 2015-16 year in review. The team launched their Uncle SAM hybrid rocket to 6000ft.
