Demonstration of 156 Inch Motor with Segmented Fiberglass Case and Ablative Nozzle. Volume II--Static Test and Hydroburst
Abstract
The primary objectives of the program were to successfully static test fire the rocket motor followed by a hydroburst test of the fiberglass case. These objectives were attained. The motor (156-8) was static test fired 25 Jun 1968 and all systems performed satisfactorily. This test successfully demonstrated the segmented fiberglass case design and the joint seal design. All motor and nozzle components were intact and in good condition at the completion of the test. The motor operated at close to predicted ballistic values. Post- test inspection of the motor and components disclosed that the internal insulation, nozzle design, and joint seal design were satisfactory and the nozzle performed as predicted. Inadequacies in the CO2 quench system permitted some charring through of the insulation in the forward dome which necessitated repair prior to the hydroburst test on 8 Aug 1968. Burst occurred at 1,095 psi, starting in a heat affected area of the forward segment.
