DEMONSTRATION OF 156 INCH MOTOR WITH SEGMENTED FIBERGLASS CASE AND ABLATIVE NOZZLE.
Abstract
This program was established by the Air Force Rocket Propulsion Laboratory to demonstrate a segmented fiberglass case and an ambient pressure cured ablative nozzle in an actual motor firing. The development of manufacturing processes and handling techniques for the insulating and loading of a segmented fiberglass case is a primary objective of this program. The segmented fiberglass case was designed by Thiokol Chemical Corporation and fabricated by B. F. Goodrich Company. The fixed ablative nozzle was fabricated by Thompson Ramo Wooldridge. The technical effort on this demonstration program was initiated on 2 May 1966. Asbestos filled NBR insulation was installed in each case segment and the segments assembled for hydrostatic proof testing. The segmented fiberglass case joint seals, located in the joint NBR insulation, were verified through a hydrostatic proof test at 880 psig (maximum expected motor operating pressure) for 123 seconds. Following verification of the integrity of the motor case, bladder and seals, the case segments were disassembled and dome insulation was completed. (Author)
