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.

    本发明涉及一种具有超声波水流切割降阻功能的航行器装置,包括航行器本体,航行器本体的航行前进端设置有球鼻艏与首舷,在球鼻艏或首舷上还安装有超声波水流切割降阻机构,超声波水流切割降阻机构包括水流切割板件、减震部件、超声波振动源,水流切割板件通过减震部件固定安装于球鼻艏或首舷上,超声波振动源安装于水流切割板件内侧设有的安装空腔中,以驱动水流切割板件作高频超声切割振动。本航行器装置利用超声波水流切割降阻机构工作时产生超高频超声波切割运动,对球鼻艏或首舷位置的水流进行超高速空化效应,使该位置的水产生数百万计的气泡,从而降低球鼻艏或首舷位置的水密度,进而降低航行器前进时阻力,提升航速、航程、降低能耗。
