Airborne and Ground Data Processing Systems for the RAH-66 Comanche

Abstract

The RAH-66 Comanche flight test program requires a state of the art air vehicle and avionics data system consisting of: 1) An airborne, all digital multiplexing and recording system capable of combining digital streams at very high data rates; 2) The ability to record high speed avionics busses from the MEP (Mission Equipment Package) such as MIL-STD-1553B, HSDB (High Speed Data Bus,) PI (Processor Interconnect) Bus, DFN (Data Flow Network,) and TM (Test and Measurement Bus;) 3) A miniaturized, programmable, modular/distributed high speed PCM measurement system for 550 air vehicle measurements recorded on the Comanche Flight Test Aircraft and Propulsion System Test Bed; 4) an airborne digital multiplexing and recording system for recording a composite stream on an Ampex DCRsi tape recorder; 5) A high capacity ground data processing system using parallel processing computers for real time data compression; and 6) distributed analysis system using workstations for data processing with centralized disk storage.
