SAP PURCHASE REQUISITION: 4200264272 STATEMENT OF WORK BACKGROUND THE ROTORCRAFT AIRCREW SYSTEMS CONCEPTS AIRBORNE LABORATORY (RASCAL) PROJECT WITHIN THE FLIGHT CONTROL AND COCKPIT INTEGRATION DIVISION (CODE YH) OF THE U.S. ARMY AEROFLIGHTDYNAMICS DIRECTORATE HAS A NEED TO REPLACE ITS AGED AND OBSOLETE REAL-TIME SIMULATION SYSTEM. THIS SYSTEM PROVIDES THE CAPABILITY TO SIMULATE THE RELEVANT DYNAMICS OF THE RASCAL JUH-60A BLACK HAWK HELICOPTER IN REAL-TIME AND IN-THE-LOOP WITH THE PILOT AND ACTUAL AIRCRAFT FLIGHT CONTROL HARDWARE. THE CURRENT SYSTEM IS COMPOSED OF A SILICON GRAPHICS ONYX REALITY ENGINE 2 COMPUTER WITH EIGHT MIPS R10000 194 MHZ CPUS, AND THE IRIX OPERATING SYSTEM WITH REACT/PRO REAL-TIME EXTENSIONS. THE PRIMARY MATH MODEL IS THE AMES GEN HEL FORTRAN SIMULATION MODEL, WHICH IS LINKED WITH ANCILLARY SUB-SYSTEM MODELS CODED IN C. SOME SUBSYSTEM MODELS HAVE BEEN DEVELOPED IN MATLAB/SIMULINK AND INTEGRATED INTO THE REAL-TIME ENVIRONMENT USING THE MATHWORKS REAL-TIME WORKSHOP. ALL OF THESE SUBSYSTEMS MUST BE MIGRATED TO THE NEW SIMULATION ENVIRONMENT, AND COMPATIBILITY WITH NATIVE FORTRAN, C, AND MATLAB/SIMULINK AND REAL-TIME WORKSHOP MUST BE MAINTAINED. THE CURRENT REAL-TIME SIMULATION SYSTEM INTERFACES WITH AIRCRAFT FLIGHT CONTROL HARDWARE VIA VME-BASED CARDS THAT SUPPORT A MIL-STD-1553B MULTIPLEX DATA BUS, ANALOG I/O, DISCRETE I/O, AND FREQUENCY CLOCKING. THE REPLACEMENT REAL-TIME SIMULATION SYSTEM MUST ALSO BE ABLE TO INTERFACE WITH THESE VME I/O CARDS. REQUIREMENT THE RASCAL PROJECT REQUIRES A REAL-TIME COMPUTER SIMULATION SYSTEM WITH THE FOLLOWING CAPABILITIES AND PERFORMANCE SPECIFICATIONS EQUAL TO OR EXCEEDING THE FOLLOWING. 1. REAL-TIME ARCHITECTURE: THE REAL-TIME SIMULATION SYSTEM MUST PROVIDE A TIME-DETERMINISTIC REAL-TIME SIMULATION CAPABILITY INCLUDING UTILITIES TO DEVELOP REAL-TIME APPLICATIONS, CONTINUOUSLY EXECUTE REAL-TIME APPLICATIONS, MONITOR REAL-TIME APPLICATIONS, SCHEDULE REAL-TIME PROCESSES, TUNE SYSTEM PERFORMANCE, AND MONITOR EVENTS AND DATA FLOWS IN REAL-TIME. 2. REAL-TIME OPERATING SYSTEM (RTOS): THE REAL-TIME SIMULATION SYSTEM MUST INCLUDE A LINUX-BASED REAL-TIME OPERATING SYSTEM WHICH LEVERAGES MANY OF THE OPEN-SOURCE LINUX DEVELOPMENT TOOLS AND UTILITIES. THE RTOS SHOULD BE BASED ON ONE OF THE COMMONLY AVAILABLE STANDARD LINUX DISTRIBUTIONS. 3. DEVELOPMENT ENVIRONMENT: THE REAL-TIME SIMULATION SYSTEM MUST PROVIDE TOOLS TO DEVELOP REAL-TIME APPLICATIONS AND BE COMPATIBLE WITH EXISTING DEVELOPMENT TOOLS EMPLOYED BY THE RASCAL PROJECT. THE SYSTEM MUST INCLUDE NATIVE FORTRAN AND C COMPILERS AND A SOURCE-LEVEL DEBUGGER. THE SYSTEM MUST ALSO MAINTAIN COMPATIBILITY WITH THE MATHWORKS SIMULATION DEVELOPMENT TOOLS, INCLUDING MATLAB/SIMULINK, REAL-TIME WORKSHOP, AND EMBEDDED CODER. CODE DEVELOPED USING EACH OF THESE LANGUAGES AND TOOLS MUST BE SEAMLESSLY INTEGRATED IN THE REAL-TIME SIMULATION SYSTEM FOR REAL-TIME EXECUTION. 4. SIMULATION CONTROL, ANALYSIS, AND VISUALIZATION CAPABILITIES: THE REAL-TIME SIMULATION SYSTEM MUST PROVIDE THE CAPABILITY TO START AND STOP SIMULATIONS, RECORD SIMULATION DATA, PLAYBACK SIMULATION RUNS, PLOT SIMULATION DATA IN REAL-TIME AND OFF-LINE, AND EXPORT SIMULATION DATA TO OTHER APPLICATIONS. THE SYSTEM MUST PROVIDE ACCESS TO ALL INTERNAL SIMULATION SUBSYSTEMS AND VARIABLES FOR THE PURPOSES OF MONITORING AND RECORDING DATA. 5. HARDWARE COMPATIBILITY: THE REAL-TIME SIMULATION SYSTEM HARDWARE MUST BE CAPABLE OF INTERFACING WITH THE FOLLOWING VME I/O CARDS WITH MINIMAL LATENCY: SBS TECHNOLOGIES ABI-V6-2 AND ASF-V6-2 MIL-STD-1553B MULTIPLEX DATA BUS CARDS; XYCOM XVME-244 DIGITAL I/O CARD; SBS GREENSPRING VIPC616 INDUSTRYPACK ANALOG I/O CARD; AND DATUM BANCOMM BC635VME TIME AND FREQUENCY PROCESSOR. TO ACHIEVE THIS, EITHER VME-BASED REAL-TIME SIMULATION SYSTEMS OR PCI-BASED REAL-TIME-SIMULATION SYSTEMS WITH A PCI-TO-VME BRIDGE ARE ACCEPTABLE. PCI-TO-VME BRIDGE SYSTEMS MUST INTRODUCE NO MORE THAN 100 MICROSECONDS OF DELAY INTO THE CLOSED-LOOP SY
