To provide a moving body capable of quickly moving in the width direction and preventing devices provided on the main body from being wetted with water. [Solution] The moving body 1 comprises a main body 2 capable of floating on the water surface WS, a fan 6 provided on the main body 2 and capable of generating an air current directed outward from the main body 2 in the width direction of the main body 2, and a guide surface 72a provided on the main body 2 and receiving a reaction force by guiding the air current generated by the fan 6. The guide surface 72a is positioned at a position offset from the center point CP of the main body 2 in the width direction, and is configured to change the traveling direction of the air current generated by the fan 6 and increase the upward directivity of the air current.

The application discloses a method for detecting the flap opening position of a hovercraft cushion lifting fan, and relates to the technical field of hovercrafts.The method for detecting the flap opening position of the hovercraft cushion lifting fan is based on the flap angle value detected by an angle sensor and the output signal of a position sensor to perform fault monitoring on the position sensor.When all the position sensors are working normally, the output signal of the position sensor is used to determine the flap opening position during the flap action.When a fault occurs in the position sensor, a fault alarm is output, and the flap angle value of the angle sensor is used to determine the flap opening position during the flap action.The application can not only detect whether a fault occurs in the position sensor in real time through the angle sensor, but also ensure the accuracy of the flap action through a more reasonable flap opening detection method, so that the hovercraft can reach a predetermined cushion lifting posture, and the safety of the hovercraft during navigation is ensured.

The invention belongs to the technical field of air cushion suspension transportation equipment, and relates to an air cushion suspension ship with a lift low-wind-resistance bow body, the air cushion suspension ship comprises a ship body main frame, an arc streamline bow body and a stern body, the arc streamline bow body and the stern body are symmetrically arranged at the two ends of the ship body main frame, the sweepback angle of the front edge of the bow is 17-18.3 degrees, and the downward inclination angle of the lower edge of the bow is 5-7 degrees to form a front air seal. An integrally-formed air cushion flow guide enclosure shell is arranged on the lower portion of the ship body main frame, the air cushion flow guide enclosure shell, the ship head and the ship tail define an air cushion positive pressure cavity, and a ground effect air cushion is formed through air supply of front and rear duct booster fans to achieve non-contact suspension. The system further comprises a splayed symmetrical four-rotor power system, and four groups of rotor assemblies are fixed through vertical left and right motor mounting brackets to form a main propulsion and posture adjusting unit. Wind resistance is reduced and lifting torque is generated through the bow at a specific angle, air leakage is restrained in cooperation with an air seal structure, and low-wind-resistance, zero-friction suspension and high-stability control are achieved.

Remove the known mobile body "dust" defects. Is not to produce dust and can clean mobile body, is set to integrated duct fan effect and ground effect, anti-torque, and fluid mechanics of the theory and build and float the invention of the device.

The application discloses an improved amphibious small hovercraft, and relates to the technical field of hovercrafts, which comprises a main hull, an air cushion, a curtain, a propulsion system and a control system, wherein the main hull is divided into an upper hull layer, a middle hull layer and a lower hull layer from top to bottom; a driver cabin, a passenger cabin and a power fan are arranged from front to back on the upper hull layer; a supercritical CO2 power generation system, a switched reluctance speed regulation and a magnetic suspension centrifugal air compressor are arranged on the middle hull layer; a CO2 recovery chamber is arranged in the middle of the lower hull layer; and the air cushion and the curtain are arranged on the outer wall of the main hull. The application has high efficiency and strong adaptability, and can freely pass through water, marsh, ice and soft sand; the supercritical CO2 heat circulation system is not limited by temperature, and the improved hovercraft can replace fuel vehicles and new energy electric vehicles through technical innovation.
