Deployment Testing Procedure - IREC 2022
Equipment
Avionics Bay
2x RRC3s
No batteries
Body tubes with charge wires inserted and secured in bulkheads
7.4v 2S LiPo
XT90 male adapter
Payload Sabot
2x ~6" ferrule to bare 18-22 AWG extender wires
Machine with ground software
Engine controller (normally used for prop)
Ethernet cable / adapter (if necessary)
Test
Place primary RRC3 into output test mode
Screw ferrule crimps of extenders into primary RRC3 battery connector
Place bare end of extenders near umbilical slot
Insert avionics bay into body tube, plug in deployment DE-9 cables
Place engine controller maximum distance away (~12 ft)
Plug 7.4v LiPo XT90 to 12v input of engine controller
Power on the Teensy in engine controller box with external USB power (since converter expects 12v)
Verify heartbeat received from engine controller
Run engine controller igniter cable to rocket
Use pliers to grab extender wires connected to RRC3 power input
Use WAGO connectors to attach extender wires to igniter output cable
Wire two ematches in parallel to primary RRC3 drogue charge lines (also in parallel)
Before handling BP, move all personnel possible to safe distance (> 12 ft)
Place ematches in black powder balloon
Tape balloon into drogue charge cap
Fully assemble remaining body tubes
Make sure avionics bay screw switch is in disarmed position (e.g. OPEN)
Verify all connections
Arm the screw switch
Move all personnel to a safe distance (> 12 ft) - no exceptions
Power on the engine controller box with switch - at this point the test is live
Place the engine controller in "hot" mode
When ready, toggle the igniter output of the engine controller through the ground software
Verify the RRC3 beeped the correct continuity sequence for 1s
Verify that after 1s the charge is ignited and the tubes separate
Repeat for primary drogue, secondary main, and secondary drogue.
