Abstract
THE ANALYSIS OF AIRCRAFT AND HELICOPTER PROPULSION SYSTEM SUCH AS COMPRESSORS, GAS TURBINES, PROPELLERS AND ROTORS REQUIRES THE USE OF SLIP-RING DEVICES TO INTERFACE WITH THE LARGE ARRAYS OF SENSING ELEMENTS ON THE MOVING MEMBER. THE CONVENTIONAL MECHANICAL SLIP-RING DEVICES ARE SPEED, NOISE, SIZE AND LIFE-TIME LIMITED. THE OBJECTIVE OF THIS EFFORT IS TO DEVELOP A HIGH-SPEED, ELECTRO-OPTIC SLIP RING DEVICE THAT WILL EXPAND THE POTENTIAL CAPABILITY FOR ANALYSIS WITH ROTATING OR MOVING SYSTEMS AND FORM THE BASIS FOR A COMMERCIAL DEVICE. THE PHASE I TASK SHALL DEMONSTRATE THE FEASIBILITY OF AN OPTICAL SLIP-RING DEVICE BASED ON THE INTEGRATION OF HIGH-SPEED ELECTRO-OPTICAL COMPONENTS WITH AN OPTICAL LINK FOR DATA TRANSFER FROM A ROTATING SHAFT. MODULAR COMPONENTS THAT FORM THE BASIC ELEMENTS OF THE SLIP-RING WILL FIRST BE DEVELOPED AND TESTED (MULTIPLEX/DEMULTIPLEX MODULES, A HIGH SPEED MODULATED SOURCE AND RECEIVER AND A OPTICAL LINK) AND THEN INTEGRATED INTO A LABORATORY MOCKUP OF A ROTATING SHAFT SYSTEM TO DEMONSTRATE THE FEASIBILITY OF THE OPTICAL SLIP-RING CONCEPT. THIS DATA WILL IDENTIFY BASIC COMPONENTS, NEEDS FOR SPECIAL COMPACT HYBRID CIRCUITS, DIRECTIONS FOR PHASE II AND APPLICATION AREAS FOR A UNIVERSAL SLIP-RING DEVICE.
