Purpose

The purpose of the mission package tube is to provide structure for the rocket and enclose other components with a smooth aerodynamic surface.

Materials

  •  

Tools

  • Radial indexer 
  • Center Drill
  • 23/64 Drill Bit
  • 27/64 Drill Bit
  • 39/64 Drill Bit
  • 100 degree Countersink

Requirements

  • Mission package tube ID must interface correctly with FRR

  • Must be the correct length for the rocket to have a stable margin

  • Must allow access to cameras and avionics controls

  • Must withstand axial load from the piston recovery system

Manufacturing

  • Set up radial indexer. Tram with dial indicator to 2 thousands of an inch accuracy in x and y, tram to 10 thousandths of an inch radially.

  • Started with a stock of length 23 15/16" (this is just the size of the one from wildman, but anything that is 19.5" or longer works)

  • Left 2" for clamping space on one side 
  • Center drill --> through hole --> counter sink
    • Drill holes at 1200 RPM & counter sink at 200 RPM 
  • Move to the next set of holes based on drawing.
  • Flip the tube after the first half set of holes to finish the rest. 
  • Cut the tube to size, leaving 0.01" extra which would be sanded down to exact size
  • No labels
