Spike support redesign

James, Matt and Connie have re-designed the supports that hold the nozzle spike into the combustion chamber of the Pyralis engine. The new support design will be more resilient to thermal expansion, vibration, and machining tolerances. Using this design will better control the nozzle’s throat area, leading to more consistent and predicable thrust.
