Abstract:

Ultrasonic motors are novel devices that operate based on the piezoelectric effect. A "smart material" piezoceramic (Lead Zirconium Titanate, PZT) ring is excited by electrical signals and generates a traveling surface wave. The traveling surface wave drives a rotor through a toothed stator. These motors have several distinct advantages: low profile, high torque at low speeds, quick response, insensitivity to magnetic fields, non-sparking, quiet operation, and efficiency. USMs therefore are suited for many aerospace applications. Aerotech proposes to develop USM-based actuator technologies for military and civilian applications. During Phase I, two USM-based mechanisms will be designed for missile applications -- flight control surface (flaps, ailerons, rudders, trim, etc.) actuation and safe/arm devices. PZT toughening methods will also be investigated to enhance the longevity of USMs. During Phase II, the mechanisms will be fabricated and tested, and process design for the volume manufacture of USMs will be conducted. During Phase III, commercialization of this technology will be undertaken. Several military and commercial applications of USMs are identified and discussed. Aerotech has formed a strategic alliance with the DOE/Allied Signal's Kansas City Plant to develop USM technology for military and commercial applications through a systematic Phase I, II, and III effort.
