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.
