Introduction
For this document, it is assumed that a minimum of two people are present at the firing:
- The Firing Director (FD)
- The Safety Officer (SO)
However, it is suggested that the following people be present as well:
- The Operations Overseer (OO)
- The Data Recorder (DR)
For more on the positions, see Responsibilities of the Rail Gun Team.
-
-
Attach 5 point control wire to EMRG
-
Attach 2 point charging cable to EMRG
-
Take wires and manual discharge pin string back to control bunker
-
-
-
Attach 25 pin data wire to diagnostic box
-
Attach 9 pin data wire to diagnostic box
-
Attach BNC power cable to diagnostic box
-
-
-
Close lid of HSCSB to protect the camera
-
Turn on the lights.
-
-
-
Connect 2 point charging cable to the charging box.
-
Connect 25 pin data cable to the control box
-
Connect 5 point control cable to control box
-
Connect 9 pin data cable to control box
-
Connect power supply to control box
-
DO NOT Plug in Control or Charging box to Wall Power
-
-
-
Turn on LabView and load the TirggerCheck.VI file that contains the firing/data acquisition logic.
-
Test the measurements and make sure the connections to the physical data acquisition system are correct and functional.
-
-
-
Insert projectile from breach (end opposite of target), pointed end first
-
Gently push projectile until fins are completely within the rails. Use ramrod as needed
-
Remove ramrod.
-
Place ramrod in a visible location in the firing room.
-
-
-
Bolt injector to EMRG
-
-
-
Turn off voltage meter and remove from EMRG.
-
Bring the voltage meter into the firing control room.
-
-
-
Pressurize piping.
-
This is the last action before clearing the firing chamber. Check with other team member(s) to ensure completion of their tasks before performing this step.
-
Slowly open the pressure valve until the pressure gauge reads the desired pressure.
-
For a test fire, the nitrogen is turned off once the system is pressured.
-
For A full firing, the nitrogen is left on until after discharge.
-
Caution: A choking hazard now exists due to possible high concentrations of nitrogen in the area around the EMRG.
-
Caution: The EMRG is now capable of launching a projectile. DO NOT Stand down range of the EMRG without first stopping the gas flow, removing the projectile, and removing the injector system.
-
-
-
Have Safety Officer bring Fire extinguisher into control bunker
-
-
-
Ensure all personnel are out of the firing area once the nitrogen is attached and open.
-
-
-
Close door to EMRG
-
Activate Red Safety Light on door to EMRG.
-
-
-
Plug control box into wall power
-
For a nitrogen only test, skip to Step 20.
-
-
-
Plug charging box into wall power
-
-
-
Turn resistor bank OFF
-
-
-
Turn charging box to ON
-
-
-
Charge EMRG to appropriate voltage (450V for full firing)
-
Warning: EMRG is now extremely extremely dangerous. DO NOT enter the firing bunker without completing the entire discharge procedure.
-
Pass out and put on ear and eye protection
-
-
-
Turn charging box OFF
-
-
-
Disconnect charging box from wall.
-
Disconnect charging cable from charging box and place cable into the EMRG room. DO NOT reconnect the cable until a discharge has occurred.
-
-
-
Turn control box power supply on
-
Turn voltage and current to zero, then raise voltage to 5V
-
Connect the control box to the computer
-
Connect the control box to the wall power
-
Upload the Arduino Data
-
