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

The invention discloses a self-adaptively deformable fluid vehicle increasing thrust and retreating structure, which belongs to the field of ships and marine engineering. The present invention includes several booster backstops; the booster backstops include a hinge and an asymmetric flap structure; the hinge is fixed on the bottom of the fluid aircraft through a hinge seat, and the asymmetric flap structure has hole through which the hinge passes; the hinge rotates in the hinge seat. When the fluid vehicle is navigating in an oscillating fluid environment, the structure can perform adaptive flipping according to the direction of the fluid vehicle's oscillating motion, thereby increasing the fluid resistance of the vehicle when it retreats, effectively curbing its tendency to retreat, and achieving Increase the effect of pushing and stopping, and improve the navigation efficiency of the fluid aircraft. In addition, since the present invention has the characteristic of self-adaptive deformation, it can effectively reduce the influence of the structure on the surface roughness of the fluid vehicle without significantly increasing the sailing resistance.
Description
technical field [0001] The invention belongs to the field of ships and marine engineering, and relates to a push-increasing and anti-backward structure for a fluid vehicle that can be adaptively deformed. Background technique [0002] In recent years, fluid vehicles have been widely used in engineering practice, which widely exist in oceans, rivers, biological liquids and air. Some unmanned fluid vehicles play a vital role in the fields of resource exploration, environmental monitoring and military reconnaissance. [0003] The sailing speed is a key parameter to evaluate the overall performance of a fluid vehicle. 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 airflow, as well as the limitation of their own driving ability, it is difficult for some vehicles to always move along a given course in an oscillating fluid environment, such as some small unm...
