MIL-STD-1553B DATA BUS

THE INCREASINGLY WIDESPREAD APPLICATION OF MIL-STD-1553B TO MILITARY AND, POTNTIALLY COMMERCIAL AIRCRAFT HAS CREATED A NEED FOR DIGITAL OUTPUT FLOW ANGLE TRANSMITTERS. THE CURRENT MEANS OF GENERATING A DIGITAL OUTPUT FROM EXISITING TRANSDUCERS HAS AN UNFLAVORABLE IMPACT ON SIZE, WEIGHT, POWER, COST AND RELIABILITY. DIGITIAL ENCODING TECHNIQUES ARE BELIEVED TO HAVE BENEFICIAL APPLICATION TO EXISTING TO EXISTING TRANSMITTERS BY REPLACING THE ANALOG OUTPUT STATE, TO RESULT IN A DIRECT DIGTAL OUTPUT MORE SUITABLE FOR CONVERSION TO THE MIL-STD-1533B DATA BUS. A PROGRAM IS PROPOSED HEREIN TO DETERMINE THE BEST APPROACH FOR IMPLEMENTING AN ENCODER OUTPUT IN EXISTING ANGLE OF ATTACK TRANSMITTERS. COMPLEXITY OF REQUIRED INTERFACE ELECTRONICS FOR MIL-STD-1553 OUTPUT WILL ALSO BE RESEARCHED. OTHER WORK INCLUDES STUDY OF EXPECTED SIZE, WEIGHT, POWER AND RESPONSE DYNAMICS. COST IMPACT AND ABILITY TO MEET REDUNDANCY AND SELF TEST REQUIREMENTS ARE OTHER IMPORTANT ISSUES THAT WILL BE DEALT WITH BRIEFLY IN THIS PHASE. RESEARCH IN THIS PHASE WILL LAY THE GROUNDWORK FOR PRODUCT DEVELOPMENT, TESTING AND COMMERCIALIZATION IN LATER PHASES.
