  • Patent number: 11975824
    Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of an odd number of rotors. The odd or auxiliary rotor is designed to be smaller in diameter than the remaining main rotors and accordingly generates a smaller unbalanced torque and pitch on the aircraft. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.

  • Patent number: 6658118
    Abstract: Apparatus for suppressing fluid-borne noise in a fluid conduit (12 or 12a) that includes a vibration sensor (36, 36a or 36b) for operative coupling to the conduit for providing an electrical sensor signal as a function of fluid pressure fluctuations in the conduit. A piezoelectric actuator (40, 40a or 40b) is adapted to be mounted on the conduit for imparting pressure fluctuations to fluid in the conduit. An electronic controller (38, 38a or 38b) is responsive to the sensor signal for energizing the actuator 180° out of phase with fluid pressure fluctuations sensed by the sensor. The sensor may be either closely coupled to the actuator, or separate from the actuator and disposed upstream of the actuator with respect to the direction of fluid flow through the conduit. The sensor in the preferred embodiments of the invention comprises a piezoelectric sensor, and the actuator comprises a stack of piezoelectric elements.
