Medusa Booster Cup

Requirements

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

Details

The booster cup is made from a fiberglass coupler tube (<add length here>in long, inner diameter 5.820in, outer diameter 5.998in). It includes 12 radial holes of drill size 6-32 with centers located 0.3 in. from the edge of one side of the cylinder for interfacing with the diaphragm.

Risks: Holes shear during separation

Manufacturing

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. Level the radial indexer using a mallet and pressure gauge (use paper to level vertically if needed).
   1. While leveling the radial indexer keep in mind that there may be deformities on the surface of the indexer which may affect pressure readings
5. Add holes using the mill at 600 rpm and 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.
      
6. Sand interior and exterior until slides smoothly into mission package tube
