Propulsion module design review. Milestone 8: Integrated Propulsion Technology Demonstrator

摘要

The propulsion module for the Integrated Propulsion Technology Demonstrator (IPTD) consists of main engine(s), and fluid, electrical, propulsion checkout and control systems (PCCS), and associated instrumentation representative of an X-33 main propulsion system (MPS). These systems are integrated within a structural support fixture which includes mounting provisions for the MPS feed lines and ancillary equipment. The weight of the main engines and associated thrust loads are reacted by a separated thrust structure mounted directly to the large structural beams (i.e., Norman Beams) of the Advanced Engine Test Facility (AETF). This document provides a summary of the design requirements, and associated design features of the major elements of the propulsion module. Significant design detail is provided for the hardware that will be procured, fabricated, assembled and delivered to MSFC in October 1995. Designs of hardware items due for fabrication at a later date (such as the thrust structure and tank modules) are presented only to the degree necessary to indicate critical interface requirements. This report also documents the findings of an independent peer of the design to ensure that major design oversights are caught early in this design and fabrication process. This peer review board consisted of senior propulsion, control, and software engineers at Rockwell who had avionics/ground control and data handling system or cryogenic design experience on the Saturn launch vehicle and/or the Shuttle.
