Self-adaptive deformation thrust-increasing retaining structure of fluid vehicle

Abstract

The invention discloses a self-adaptive deformation thrust-increasing retaining structure of a fluid vehicle, which belongs to the field of ship and ocean engineering. The thrust-increasing retainingstructure comprises a plurality of thrust-increasing retaining devices, the thrust-increasing retaining device comprises a hinge and an asymmetric turning plate structure, the hinge is fixed at the bottom of the fluid vehicle through a hinge seat, and the asymmetric turning plate structure is provided with a hole through which the hinge passes, and the hinge rotates in the hinge seat. When the fluid vehicle sails in an oscillating fluid environment, the structure can turn over in a self-adaptive mode according to the oscillating motion direction of the fluid vehicle, so that the fluid resistance borne by the vehicle in the retreating process is increased, the retreating motion trend of the vehicle is effectively restrained, the thrust increasing and retaining effects are achieved, and thenavigation efficiency of the fluid vehicle is improved. Besides, the self-adaptive deformation characteristic is achieved, so that the influence of the structure on the surface roughness of the fluidaircraft can be effectively reduced, and the navigation resistance cannot be remarkably increased.

Description

technical field [0001] The invention belongs to the field of ships and marine engineering, and relates to a self-adaptively deformable fluid aircraft boosting and anti-retreating structure. Background technique [0002] In recent years, fluid vehicles have been widely used in engineering practice, and they widely exist in oceans, rivers, biological fluids and air. Some unmanned fluid vehicles play a vital role in fields such as resource exploration, environmental monitoring, and military reconnaissance. [0003] Sailing speed is a key parameter to evaluate the overall performance of fluid vehicles, and faster sailing speed means higher work efficiency and less energy consumption. However, due to the interference of environmental factors such as waves, ocean currents, and air currents, as well as the limitation of its own driving ability, it is difficult for some aircraft to always move along a predetermined course in an oscillating fluid environment, such as some small unma...

AI Technical Summary

Problems solved by technology

However, this structure has the following two disadvantages: first, it will significantly increase the roughness of the surface of the fluid vehicle, thereby increasing the sailing resistance; second, due to the impact of roughness, the structure cannot be designed very large, therefore cannot be used in larger fluid craft
