Purpose:

The nose cone bulkhead connects the parachute to the nose cone.

Requirements:

  • Must withstand shock forces applied to each U-bolt hole (26 lbf each)

  • Must fit within the airframe

  • Must be able to interface with U-bolt

  • Must be able to interface with nose cone

Details/Design:

Material: Aluminum 6061 T6

Mass (from CAD model): 0.05 lbs

Safety Factor: 3.4


The Nose Cone Bulkhead connects the parachute to the nose cone via the u-bolt and nose cone coupler and withstands shock forces during recovery deployment. It includes two tapped holes that connect to the u-bolt. 

FEA:

Forces considered: 26lbf shock forces at each u-bolt hole

Manufacturing:

Plan

  1. Waterjet profile
    1. Leave holes slightly undersized
  2. Tap holes

Testing:

  • Piston deployed during ground testing
  • No labels
