Supplies

Boxes

  • LV3 Box
  • LV3 Small Hardware

1. Rocket Stand

  • Verify that the stand is assembled and correctly tightened.

2. Assembling Rocket

  • Verify that the protection rings are removed prior to assembly.
  • Torque Settings: 40 in/oz
  • First 3 screws as equilateral triangle (every other hole, the order doesn't matter.)
  • Note: on some modules screw length matters.
  • Put in the spider before attaching the motor.
  • Spider can be a little finicky. Wiggle it.
  • Make sure the washers go back to their spots.

3. Sequence 1

  • Tape on the key to the motor casing
  • Take the protective rings off the motor module and the fin can.
  • Remove the bottom protective ring from the fin can.
  • If the key is taped on, remove the key first before the shake test.**
  • Insert the motor in the motor casing.
  • Thrust flange, flatside towards space.
  • Figure out the correct wench size for 3/8 nut.
  • Put the fin can on the motor casing.
  • 14mm wench is close enough.
  • Before screwing the motor onto the fin can, put the motor module (with the spider attached) onto the motor mount.
  • When the bolt is threaded through the top of the spiper, someone needs to hold the key ring tool.
  • Screws should be in to make sure everything is aligned before tightening everything down.
  • Fasten the modules together.
  • When putting in the screws, make sure they are locktight!
  • Use the bar to hold the key ring stationary as the bolt is attached through the spider. Tighten it until the motor doesn't jiggle.
  • 1/4 in screws for the thrust flange
  • Check the tightness of the top bolt again.
  • Check for any shakyness
  • Put onto stand (See diagram)
  • DIAGRAM ... Flight Computer
  • Need technical diagram for the computer module.
  • Remove the protective rings
  • Remove the protective rings from the umbilical ring.
  • Electrical connectors are color coded.
  • When two modules are put together, they need to be screwed together or they will not stay together.
  • When putting the umbilical onto the flight computer, the flight computer cables go through the marked (red) hole.
  • 1 cable attaches, 3 pass through.
  • Next, remove the protective rings for the camera ring.
  • Wires go through the marked hole.
  • Do not remove the tape from the cameras.
  • Remove the bottom protective ring from the flight computer (blue).
  • Prior to attaching the flight computer to the motor module, attach Airframe temp sensor.
  • When attaching the flight computer to the base (motor module), the "back" aligns to the rail sled.
  • Use the coupling example diagram for knowing the screw sizes. ...
  • Remove the top from the RCS module.
  • Remove the protective rings from ENSR.
  • Push it until it is tight, then pull back a quarter turn
  • ENSR, rear to rail sled
  • Next attach the nose code to the top of the ENSR.
  • The ENSR sub assembly will already have the nose cone attached.
  • Need to re-make one of the top layers of the rail sleds.
