Cup

Design

Requirements:

1. Shall contain soft goods prior to separation
2. Shall withstand separation loads
3. Shall separate from the nose cone/staging cone

Material: Fiberglass coupler tube

Risks: Holes shear during separation (insert link to past issues)

Features:

• Radial holes (12 holes of size 6-32 placed 0.3 in. from top of tube) for interfacing with the diaphragm

Manufacturing

Operations:

1. Cut coupler tube to length on the horizontal bandsaw
   
2. Sand faces to level
3. Cut a piece of supporting material to go inside the cup while machining it
4. Add holes with radial indexer (*Note: add holes 0.3 inches from the side that has the better machine-finish)
   1. 12 holes equate to 3 1/3 turns for each hole on the 18-radius marker on the radial indexer in N-51
   2. Safety note: use air gun to blow away fiberglass dust as soon as each hole has been completed.
      
5. Sand interior and exterior until slides smoothly into mission package tube
