Test 2020-2

4 grain 54mm Everclear motor with pyrodex pellet ignition in 3-inch test mule flown on 10 October 2020 at October Fun Fly in Argonia, KS.

Used 4-grain 54mm Brazell case, #32 (0.5" throat) Loki-style nozzle, forward closure had pressure sensor and EasyMotor protototype mounted. Three grains with 0.5" cores (I think!), nozzle end grain bored out to 0.75" core.

Burnsim called this a 21% K-788, with about 1.97 sec burn time, and max pressure on a somewhat progressive burn of 923.6 psi.

Results

Perfect flight, no damage. However, due to firmware issues, the EasyMotor failed to launch detect and so we got no motor data recorded on this flight.
