Public award description

CRG HAS RECENTLY DEVELOPED A NEW CLASS OF SHAPE MEMORY POLYMERS (SMP) THAT ARE ELECTRICALLY ACTIVATED, AS OPPOSED TO THE MORE MATURE THERMALLY ACTIVATED SMPS. ELECTRICALLY ACTIVATED SHAPE MEMORY POLYMERS (EASMP) OPEN A NEW DESIGN SPACE OF UNEXPLORED FUNCTIONALITY BEYOND WHAT HAS BEEN CONSIDERED FOR THERMALLY ACTIVATED MATERIALS. THIS PROJECT WILL COMBINE THE ADVANTAGES OF EASMP WITH THE DESIGN OF STATE-OF-THE-ART GEARBOX ISOLATORS AND INTERIOR PANELS TO PROVIDE THE ABILITY TO TUNE THESE COMPONENTS FOR SPECIFIC OPERATIONAL FREQUENCIES. WITH THE USE OF EASMP INTEGRATED COMPONENTS, BY SEMI-ACTIVELY ALTERING THE INTERIOR PANELS OR GEARBOX ISOLATORS' FREQUENCY RESPONSE, IT WILL BE POSSIBLE TO BETTER TARGET AND CONTROL PARTICULARLY IRRITATING TONES RELATED TO THE AIRCRAFT'S FLIGHT MODE. CRG PROPOSES TO ADVANCE EASMP MATURITY WHICH IS APPLICABLE ACROSS MANY OTHER APPLICATION AREAS AND HAS THE BENEFIT OF ALTERNATIVE STIMULI BOASTING ULTRA-LOW POWER REQUIREMENTS AND MORE POTENTIAL FOR FASTER SWITCHING TIMES. THIS MATERIAL WILL BE REFINED AND FURTHER DEVELOPED TO MEET THE OPERATIONAL PERFORMANCE REQUIREMENTS FOR THE ROTORCRAFT ISOLATOR APPLICATION.
