Abstract

The invention discloses a space amphibious vector propeller, belongs to the technical field of space amphibious vehicles, and aims to solve the problems existing in the prior art. The space amphibiousvector propeller comprises a supporting machine frame, a shaft-less underwater propeller, a vector propulsion control device, an air propulsion device, a propulsion conversion device, a propeller fixing device and a waterproof connector, wherein a spherical groove formed by the shaft-less underwater propeller and the supporting machine frame forms a spherical surface pair; the vector propulsion control device drives the shaft-less underwater propeller to rotate; the air propulsion device comprises an air propeller arranged in an upper machine frame, a propeller shaft with one end connected with the air propeller in a threaded mode, and a limiting block fixedly connected to the other end, penetrating through the shaft-less underwater propeller, of the propeller shaft; the propulsion conversion device is arranged in the upper machine frame, and the conversion of air and underwater propulsion is achieved through the propulsion conversion device; the propeller fixing device is arranged inthe upper machine frame, and fixing or loosening of the air propeller retracted in the upper machine frame is conducted through the propeller fixing device; and the waterproof connector is arranged in a lower machine frame, and the transmission of propeller signal and energy is achieved through the waterproof connector.

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 air propulsion machines 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...
