Development and Demonstration of an Omniaxial Flexible Seal Movable Nozzle for Thrust Vector Control

摘要

The 156-9 Motor Program, Development and Demonstration of an Omniaxial Flexible Seal for Thrust Vector Control, was conducted by Wasatch Division, Thiokel Chemical Corporation for the Air Force Space Systems Division. Primary objective of the program was to develop and successfully demonstrate an omniaxial flexible seal movable nozzle on a one million pound thrust class, 156 in. diameter motor; this objective was attained. The 156-9 motor was static test fired on 26 May 1967 and successfully demonstrated the flexible seal design and fabrication concept for movable nozzles. All motor and nozzle components were intact and in good condition at the completion of the test. The motor operated longer and at a lower chamber pressure than predicted, but with no adverse effect on the overall objective. Post-test inspection of the motor and components disclosed that the internal insulation, nozzle design, and flexible seal design were satisfactory and the nozzle performed as predicted. The torque required for thrust vector control was demonstrated to be reasonable with respect to actuation system power requirements.
