The invention relates to an aircraft device with an ultrasonic water flow cutting resistance reducing function, which comprises an aircraft body, a bulbous bow and a head board are arranged at the navigation advancing end of the aircraft body, and an ultrasonic water flow cutting resistance reducing mechanism is further mounted on the bulbous bow or the head board. The ultrasonic water flow cutting resistance reducing mechanism comprises a water flow cutting plate, a damping component and an ultrasonic vibration source, the water flow cutting plate is fixedly installed on the bulbous bow or the bow board through the damping component, and the ultrasonic vibration source is installed in an installation cavity formed in the inner side of the water flow cutting plate so as to drive the water flow cutting plate to conduct high-frequency ultrasonic cutting vibration. According to the aircraft device, ultrahigh-frequency ultrasonic cutting motion is generated when the ultrasonic water flow cutting resistance reducing mechanism works, the ultrahigh-speed cavitation effect is conducted on water flow at the bulbous bow position or the head board position, the water at the position generates millions of bubbles, and therefore the water density at the bulbous bow position or the head board position is reduced, the advancing resistance of the aircraft is reduced, and the aircraft device is more stable in performance. Navigational speed and voyage are improved, and energy consumption is reduced.
