Propulsion system and aircraft

Abstract

The propulsion system comprises a main shaft, an impeller assembly, a flow guide nose cone, a flow guide cover, a plurality of nozzles and a plurality of flow guide sliding plates, and the impeller assembly is rotationally connected to the periphery of the main shaft; the impeller assembly is sleeved with the flow guide cover, and the flow guide cover and the impeller assembly form a water flow cavity. The nozzles are respectively arranged at the joints of the aircraft body and the fairing; the multiple flow guide sliding plates are slidably connected into the nozzles correspondingly. The propulsion system is arranged at the front end of the aircraft body, water flow enters from the flow inlet between the flow guide nose cone and the flow guide cover and is conveyed to the nozzle through the guiding and conveying effect of the impeller assembly, and the water flow is controlled to be sprayed out towards the outer rear portion or the outer front portion by controlling the front-back position of the flow guide sliding plate at the nozzle. The vehicle body is pushed to advance or retreat by using the counter force of the water flow spraying force, and the steering and up-down floating actions of the vehicle body are controlled by controlling the water flow spraying conditions of different nozzles, so that the steering flexibility of the vehicle body is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft propulsion, and more particularly, relates to a propulsion system and an aircraft. Background technique [0002] In ocean exploration and seabed salvage operations, underwater vehicles are often used. Vehicles have the advantages of wide range of activities, deep diving depth, and high intelligence, and are widely used in many fields. The propulsion system is the core system of the aircraft, and its performance determines the overall performance of the aircraft. [0003] The vehicle needs to perform operations such as forward, backward and steering underwater. Corresponding to different operation methods, complex structures need to be set up to support it, which not only occupies the structural space of the vehicle, but also has low control efficiency, slow steering and backward operations. It is difficult to switch a variety of different operation modes in time, which affects the convenience of...
