Abstract

A space amphibious vector thruster belongs to the technical field of space amphibious vehicles and aims at solving the problems existing in the prior art. The invention comprises: a support frame; a shaftless underwater propeller that forms a spherical pair with a spherical groove formed on the support frame; a vector propulsion control device that drives the shaftless underwater propeller to rotate; an aerial propulsion device, the aerial propulsion device includes The air propeller arranged in the upper frame, the propeller shaft threadedly connected with the air propeller at one end and the limit block fixedly connected with the propeller shaft through the other end of the shaftless underwater propeller; the propulsion conversion arranged in the upper frame The device realizes the conversion between air and underwater propulsion through the propulsion conversion device; the propeller fixing device arranged in the upper frame is used to fix or loosen the air propeller retracted in the upper frame through the propeller fixing device; The watertight connectors in the frame realize the transmission of thruster signals and energy through the watertight connectors.

Description

technical field [0001] The invention belongs to the technical field of space amphibious aircraft, and in particular relates to a space amphibious vector thruster. Background technique [0002] Due to the inherent defects of a single space robot, driven by scientific research and military needs, major oceanic countries in the world are stepping up research on space amphibious robot technology. At present, there are few studies on the integrated thruster and space vector propulsion technology of space amphibious robots, but with the development of space amphibious robots, this technology urgently needs a breakthrough. [0003] At present, space amphibious propellers are all decentralized structures, that is, underwater propellers and aerial propellers cannot be integrated, which leads to large volume and mass of propellers, low energy utilization rate, and propellers can only achieve one-way propulsion , poor flexibility. Contents of the invention [0004] The object of th...
