Abstract

The invention discloses a medium-crossing vehicle based on a common rotor and a cycloidal propeller, which includes a body of a vehicle, a horizontal support frame, and a medium-crossing propeller, and the end of the horizontal support frame is connected to the propeller tilting device. The cross-medium pusher is connected, and the propeller tilting device is used to drive the cross-medium pusher to rotate in the vertical plane around the axis of the horizontal support frame; the cross-medium pusher has multiple The blades are evenly distributed on the axis of the medium propeller, and the cross-medium propeller is connected to the root of the blade through a blade turning device. The present invention proposes a deformable thruster that takes into account both air and underwater fluid performance characteristics. A set of propellers can be used to realize omnidirectional maneuvering in the air and underwater, and fixed-point hovering, and the water-entry slamming force and storage space are reduced through composite deformation.

Description

technical field [0001] The invention relates to the technical field of water-air amphibious vehicles, in particular to a medium-crossing vehicle based on common rotors and cycloid propellers. Background technique [0002] A trans-media vehicle is a vehicle capable of flying in the air and submerging underwater. In the military field, it can complete tasks such as aerial reconnaissance, underwater detection, and penetration attacks, and can undertake different mission loads. In 2013, the U.S. Navy successfully launched a submarine-launched UAV named "XFC", which can carry photoelectric / infrared payloads and provide a new way of reconnaissance and detection for submarines. However, the "XFC" UAV itself has no power underwater, and it needs to be transported to the sea surface with the help of a carrier before it can be launched into the air. After the mission is over, it can only land on the sea surface and be recovered by the submarine. In the civilian field, in addition to ...
