Integrated Vehicle Health Management technology
The process of launching to and returning from the space constitutes the maximum cost for the space exploration. Integrated Vehicle Health Management (IVHM) when incorporated into the Reusable Launch Vehicles (RLVs) will reduce the cost of operation of the vehicles very much by improving reliability and lowering operational costs. safety and mission assurance consists of the Life cycle costs for the next generation RLVs. cost of processing, operating and maintaining the vehicle will dominate the cost and the time that is required for switching the vehicle for the next mision is necesary. Nasa conducted the X-37 IVHM flight experiment. The main aim of the experiment was to :
1) provide a limited demonstration of the benefits of in- flight IVHM to the operation of an RLV.
2)Inter operation of IVHM software and Vehicle Management Software (VMS) on the inbuilt vehicle management computer.
for the purpose of achieving these aims, the sensor data from selected subsystems is monitored by the flight software experiment and the software will perform perform real-time fault detection and isolation. The software will calculated the potential recovery operations during flight operations and during ground processing and checkout.
