Test 2020-3

4 grain 54mm Purple Pig motor with Aerotech igniter in 3-inch test mule flown on 11 October 2020 at October Fun Fly in Argonia, KS.

Used 4-grain 54mm Kosdon case, Loki-style nozzle with about an 0.390" throat, forward closure had pressure sensor and EasyMotor protototype mounted.
Four grains with 0.625" cores.

Burnsim called this a 72% J-493, with about 2.23 sec burn time, and max pressure on a relatively flat burn of 752.8 psi.

Results

Perfect flight, no damage. However, due to firmware issues, the EasyMotor captured acceleration data but no pressure data.
