Railgun Test Plan

  1. Test variac to assure that part is functioning properly. (Week 7)
    • Safety Note: Proper personal protection equipment
      • Test Points: Output socket
      • Expected Test Results: Percentage of max output which is determined by the placement of the dial.
  2. Test resistors to assure they are functioning properly. (Week 7)
    • Safety Note: Proper personal protection equipment
      • Test Points: Resistor terminal ends
      • Expected Test Results: Resistor ohmic value should fall close to listed resistance.
  3. Test switches to determine if they are functioning properly. (Week 7)
    • Safety Note: Proper personal protection equipment
      • Test Points: Load resistor terminal ends
      • Expected Test Results: Voltage should cut out completely when switch is opened. Voltage should flow when closed.
  4. Test AC/DC converter to determine proper functionality. (Week 7)
    • Safety Note: Proper personal protection equipment
      • Test Points: Load resistor terminal ends
      • Expected Test Results: Voltage output should be around max voltage input.
  5. Once assembled, test charging sub-system to determine functionality and debug and problems that may reveal themselves. (Week 8)
    • Safety Note: Proper personal protection equipment
      • Test Points: Load resistor terminal ends
      • Expected Test Results: Voltage values should be around 10 volt range and the max current that should be seen at this stage is around 190mA.
  6. Once assembled, test bleeding circuit to determine functionality and debug any problems that may reveal themselves. (Week 8)
    • Safety Note: Proper personal protection equipment
      • Test Points: Load resistor terminal ends
      • Expected Test Results: Maximum voltage value seen in the circuit should be the max voltage amount stored in the capacitor bank. The max amount of current seen flowing through the bleeding circuit should be around 50mA.
  7. Once switches are assembled into charging circuit and bleeding circuit test both to determine that switches that the switches work correctly once integrated into the system. (Week 8)
    • Safety Note: Proper personal protection equipment
      • Test Points: Load resistor terminal ends
      • Expected Test Results: Voltage should cut out completely when the switch is opened. Voltage should flow when the switch is closed.
  8. Once charging and bleeding circuit sub-systems are assembled and tested, capacitors can be tested to determine proper functionality (Week 9)
    • Safety Note: Proper personal protection equipment
      • Test Points: Capacitor resistor terminal ends
      • Expected Test Results: Capacitors should charge up close to full power at 3 time constants. Capacitors should come close to full discharge by 3 time constants.
        • NOTE: Capacitor will be tested starting with just one then adding one more with each successful test.
  9. First test firing of the system will be done once the following conditions are met:
    • Debugging and multiple successful tests of other sub-systems
    • Proper catching rig is developed and built
    • Proper safety equipment is working
  10. Once the previous conditions are met first firing will be done to insure that the module is working properly and analyze the data from each test fire to determine the efficiency.
    • Safety Note: Proper personal protection equipment
      • Test Points: Distance car travels after launch
      • Expected Test Results: The car should travel a certain distance depending on the voltage input from the user and the efficiency rating of the system.

Thrust Module Test Plan

  1. Test DAQ device. (Week 7)
    • Test Points: Test using DAQ device to control a motor via a speed controller
      • Motor tested will be a servo motor from HiTEC
      • Speed controller will be a ESC for smaller RC Helicopter setup
      • Power will come from a DC Power Supply
    • Expected Test Results: DAQ device will successfully control the servo motor
  2. Test speed controller
    • Test Points: Repeat test 1 only changing speed controller
      • Keep motor the same from test 1
      • Speed controller will be the Hacker x-110
      • DAQ device will remain the same.
    • Expected Test Results: HiTec motor responds just like test 1.
  3. Test Motor (Week 8, SZ Plate Week 7)
    • Test Points: Repeat test 2 changing Motor (no propeller/purchased motor)
      • Motor will change to the Hacker A60 (with adapter plate to table)
      • Speed controller will remain the Hacker x-110
      • DAQ device code will be altered to control motor speed
      • RPM will be verified via tachometer
    • Expected Test Results: Motor will respond according to the DAQ setting
  4. Test E-stops (Button and Pull cable Week 7)
    • Test Points: Connecting DC power supply to relay and test both button and pull cable e-stops by LED on/off circuit.
    • Expected Test Results: LED’s will show power on/off when applying the e-stops, each will work when activated.
  5. Integrated Load Cell to the DAQ (Need Load Cell/Code Week 8)
    • Test Point: Code for load cell to read forces acting on it (known weight)
    • Expected Test Results: Code will acquire forces acting on the load cell and output it into a manageable format.
  6. Test all elements together (End of Week 8)
    • Test Point: All elements together (Battery, Hacker Motor/Speed Controller, Load Cell, and DAQ device)
      • NOTE: No propeller will be connected at this point
  7. Test with propeller (Post frame build up, Tuesday Week 9)
    • Test Points: Test propeller and record data
      • This test will include the following
        • E-stop test
        • Data acquisition testing via DAQ device
        • Speed controlling test via DAQ device
        • RPM confirmation (Tachometer)
