Abstract
A propulsion apparatus using sound radiation force according to an exemplary embodiment of the present invention includes: an ultrasound generation unit which is installed at one side of an object to be operated, generates ultrasound, and provides propulsive force to the object to be operated by using sound radiation force of the ultrasound; and an ultrasound control unit which is coupled to one side of the ultrasound generation unit, and increases propulsive force to be provided to the object to be operated by controlling intensity of the ultrasound generated by the ultrasound generation unit.
Claims9
A propulsion apparatus using sound radiation force, the propulsion apparatus comprising:
- an ultrasonic transducer which is installed at one side of an object to be operated, generates ultrasound, and provides propulsive force to the object by using sound radiation force of the ultrasound;
- and
- a tube-shaped ultrasound control unit which is coupled to one side of the ultrasonic transducer, and increases propulsive force to be provided to the object by controlling intensity of the ultrasound generated by the ultrasonic transducer,
- wherein the ultrasonic transducer is configured to adjust a frequency of the ultrasound in accordance with a traveling velocity of the object in consideration of ultrasound intensity control by the tube-shaped ultrasound control unit.
