We're going to build a small hybrid rocket motor.
Adam, James, Jack, Mikolaj, David, Chris, Einar, Sam
Quaser had it's first successful test.
Need to find location nearer to Cambridge to test ignition. - contact EARS landowner?
Need to get larger valve - 8mm orifice solenoid valve rated to 60bar now possibly sourced at cost of £350 - need to check if PEEK as a seal material is Nitrous safe.
Bore out combustion chamber to ?mm ID and then get CP to remake nozzle ( or bush nozzle? ) and get igniter remade.
Re cast fuel grain. / make casting equipment and jigs
Discussed various possible different methods of ignition and potential fuels that would allow for easier ignition. Also discussed changes that could be made to improve instrumentation. Overall it was felt that the current version has quite a lot of scope remaining and we'd generally rather we got that working rather than completely redesigning the hybrid. The usefulness of having a servo valve that could be used to control the oxidiser flow was also raised.
Ask BOC about nitrous awaiting response we're golden, ask H&S about testing rocket motors, buy some fuel fuel has arrived
Ask about using the student workshop, see what Cambridge Precision will be willing to do The guy in the student workshop wanted drawings or CAD files before he agreed to anything. Cambridge precision seemed willing to machine anything we wanted.
btain SolidWorks licenses applied online, investigate valves/fittings/gas piping. BOC sell valves, and pipes, so may be the best source. Valves: http://www.leengatevalves.co.uk/. Need to know the pressures of the gas cylinder before going much further.
Find some suitable steel pipe for the case steel pipe ordered
Get in contact with the guy who can make graphite nozzles, estimate lead time/price

Look for some computer controlled valves http://aeroconsystems.com/cart/solenoid-valves/lake-axial-solenoid-valve/
David: Are these any good? http://www.finecontrols.co.uk/burkert/high-pressure-solenoid-valves http://www.solenoidvalvesuk.com/resultcatalog.asp
Sam: Obtain/test some ignition systems ignition
Team: MacKay shopping trip
Other things to obtain: nitrous safe grease, O rings
