Cal Poly Space Systems Updates

A little late to jump on this, but an update from the end of March from the Cal Poly Space team.

With Spring Break starting at Cal Poly we have good news to share about our #IREC competition rocket development. We have completed multiple tests and have decided on the rocket name – CPSS will fly Kronheim at Spaceport America.

If you follow ESRA on Facebook, they have been social media kings in posting updates on all the various teams competing at Spaceport America this year.

With systems and recovery well on the way, we plan to perform a test flight at FAR on April 15, 2017. Goals of the flight include test of structural integrity of the rocket body, honeycomb fins and bulkhead, recovery avionics, and recovery mechanism. One of the major objectives is to observe shock during main chute deployment, the data will be used to finalize size of the competition drogue parachute.

Propulsion team has finally got hydrostatic test procedures approved by EHS, thanks to our Student Safety Officer for great work done for it. Combustion chamber was successfully tested to FS of 3, Nitrous tank will be tested next week.

April 15th has come and gone, but judging by the below video they only recently attempted a static test of their engine, but was unsuccessful due to ignition problems.

I wish them luck and hopefully, we will see a rocket fly soon!

Cal Poly Space Systems – Winter Progress update

An update from Cal Poly Space Systems as they work towards the ESRA 2017 Spaceport America Cup in June.

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.

Cal Poly Space Systems 2015-16 Competition Year Review

A nice video from Cal Poly Space Systems, 2015-16 year in review. The team launched their Uncle SAM hybrid rocket to 6000ft.
