Abstract:

The objectives of this task were to 1 estimate the technology readiness of an integrated control and health monitoring ICHM system for the Aerojet 7500-1bF OTV engine preliminary design assuming space-based operations and 2 estimate the remaining cost to advance this technology to a NASA defined Readiness Level 6 by 1996 wherein the technology has been demonstrated with a system validation model in a simulated environment. The work was accomplished through the conduct of four subtasks. In Subtask I the minimally required functions for the control and monitoring system were specified. The elements required to perform these functions were specified in Subtask II. In Subtask III the technology readiness level of each element was assessed. Finally, in Subtask IV the development cost and schedule requirements were estimated for bringing each element to Readiness Level 6.
