VR-3A advanced upper stage engine system. 360 work R & D descrip. The overall objective of the work effort is to provide NASA and the USAF with initial technical, cost, and programmatic input to support the advanced upper stage engine (AUSE) requirements study. Orbitec shall develop top-level system requirements and specifications for the overall engine cycle with emphasis on the vortex cooled combustion chamber, syren acoustic igniter, fuel and oxidizer turbo pump assemblies. This effort will be structured with a baseline effort and options should additional funding become available. During the base effort, orbitec shall conduct system-level trade studies to investigate performance, estimate recurring and non-recurring costs, present a draft systems engineering management plan (SEMP), a draft risk management plan (RMP), and a draft integration and manufacturing plan. Orbitec shall hold a kickoff review, a midterm review, and a final review at the conclusion of the technical effort. Orbitec shall support the resource management, scheduling, and reporting functions for the project in accordance with the contract requirements. Orbitec shall also provide opportunities to continue additional fulfillment of goals as an option to the initial effort as described in the optional tasks below.
