Nozzle Designs

There are currently two designs being considered for the booster motor. Both designs use a graphite nozzle throat, and an aluminum carrier. the carrier is fixed to the motor case via 36 radial bolts.

Design A centers around an aluminum carrier with a graphite doughnut at the the throat.

Nozzle Design A

Design B consists of a full diameter graphite nozzle, with an aluminum carrier at the back for retention.
