The avionics bay assembly is usually the most complex part of a typical HPR. It usually does the following:

• Holds airframe/body tubes together
• Transfers recovery loads to the airframe/body tube
• Initiate ejection charges
• Log data

The assembly typically has:

• A coupler with attachment points
• At least one threaded rod to transfer loads
• An altimeter/flight computer with sensors
• A set of connectors, wires, and/or terminals which interface with energetics for deployment
• Mounting hardware
• Axial seals protecting the flight computers from the energetics
• Radial vent holes for barometric sensors
