NACES ADVANCED ELECTRONIC SEQUENCER PROGRAM

FUTURE ADVANCED SEQUENCER TECHNOLOGY (FAST)

Mar 01Escape Systems

FAST PROGRAM BACKGROUND

99 AFFORDABLE READINESS INITIATIVE SUBMITTED TO REDUCE COST OF CURRENT NACES SEQUENCER BY 50 PERCENT USING COMMERCIAL OFF THE SHELF COMPONENTS.

NACES P3I PHASE II PROGRAM TO DEVELOP ADVANCED CAPABILITY TECHNOLOGY SEQUENCER CONCEPT ALSO USING COMMERCIAL OFF-THE-SHELF (COTS) COMPONENTS FOR REDUCED COST.

DECEMBER 98 MERGER OF BOTH PROGRAMS TO DESIGN, MANUFACTURE AND QUALIFY AN ADVANCED ELECTRONIC SEQUENCER WITH COTS COMPONENTS FOR NACES.

FAST PROGRAM DESCRIPTION

PROGRAM – QUALIFY ADVANCED SEQUENCER AND APPROVE ECP TO MEET NACES LOT 16 PRODUCTION

INSTALLATION

– DEVELOP OBSOLESENCE PLAN TO CONTROL COTS COMPONENTS

– 10 YEAR WARRANTY FOR FAST CONCURRENT WITH PRODUCTION

– NAVICP PBL TO SUPPORT BASELINE AND FAST IN THE FLEET

TECHNICAL – EVENT TIMING NOW BASED ON AIRSPEED, ALTITUDE AND NOW ALSO RESULTANT DECELERATION. LIMITS

PARACHUTE OPENING LOADS. GOOD FOR EXPANDED AIRCREW POPULATION

– CONTINUOUS SENSING FOR IMPROVED FAULT TOLERANCE AND OPTIMIZED PERFORMANCE

– NEW REDUCED PARACHUTE DEPLOYMENT TIMING “BACK OF BOAT” MODE

– IMPROVED DATA RECORDING CAPABILITY

– TEMPERATURE COMPENSATION OF SENSORS

– SURFACE MOUNT TECHNOLOGY

– ADA95 LANGUAGE

– EXPANSION CAPABILITY TO INTERFACE WITH EMERGING TECHNOLOGIES
