Abstract:

THE OBJECTIVE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF DEVELOPING THE KEY COMPONENTS IN AN ICING SENSOR & ICE PROTECTION SYSTEM (ISIPS) THAT INCORPORATE PIEZOELECTRIC MATERIAL TO SENSE ICE ACCRETION AND TO INHIBITITS BUILDUP. A NOVEL CONCEPT CONCEIVED BY THE PROPOSER THATUTILIZES SOLID STATE PIEZOELECTRIC SENSOR AND ACTUATOR TECHNOLOGY INDICATES THAT IT IS POSSIBLE TO PROVIDE BOTH ICESENSING AND ICE PROTECTION WITH THE SAME MATERIAL. THE KEY ELEMENTS OF THIS SYSTEM UTILIZE POLYVINYLIDENE FLUORIDE (PVDF) TRANSDUCER FILM MATERIAL BEING EVALUATED FOR USE IN BOTH SENSING AND ACTUATING COMPONENTS AND A MICROPROCESSOR FOR DIGITAL SIGNAL FILTERING AND FOR CLOSED LOOP DEICING CONTROL. DUE TO ITS EXCELLENT PIEZOELECTRIC PROPERTIES AND BROADBAND RESPONSE, THE PVDF FILM IS ABLE TO SENSE THE VIBRATORY MOTION OF AN ICE ACCRETION SURFACE RESPONDING TO FREQUENCIES FROM A FEW HZ TO KHZ AND HIGHER. BY INCORPORATING A MICROPROCESSOR INTO THIS SYSTEM, A NUMBER OFDESIGN ADVANTAGES IMMEDIATELY BECOME AVAILABLE. IT WILL BE POSSIBLE TO CONSTRUCT AN ISIPS THAT DETERMINES THE ICE ONSET, ACCRETION AND ACCRETION RATE AND PROVIDES FOR THE CONTROLLED DISSIPATION OF ICE ON HELICOPTER BLADES, AIRCRAFTWINGS, PARKED AIRCRAFT, AIRCRAFT COMPONENTS, AIRPORT RUNWAYSAND FACILITIES, AND AIRPORT NAVIGATION AID STRUCTURES AS WELL.
