Development and validation of heat resistant rolling and deformation absorbing nozzle necks for friction and reaction force reduction

Abstract Minimizing frictional forces due to jamming between critical components such as shutters and nozzle necks is essential for ensuring the reliability of solid-propellant thrusters. This study presents innovative Rod-type and Slot-pin nozzle neck designs, incorporating rolling-structure concep...
