Embodiment Construction
[0020] With reference to each figure, a hovercraft fan aerodynamic distribution control mechanism includes an outer guide tube 6 and an inner guide tube 7, the outer guide tube 6 is provided with an inner guide tube 7, and there is a gap between the two. There is a gap, and its rear end is a closed structure, and the annular cavity formed by the gap at the front end is connected with the bottom of the ship. The inner diversion pipe 7 is composed of four arc plates, which are divided into a fixed arc plate 4 and three The movable arc plate 1, and the fixed arc plate 4 and the movable arc plate 1 are connected by a telescopic hinge 5, and the telescopic hinge 5 is to make the two movable arc plates 1 connected with the fixed arc plate 4 stretch upwards in a fan shape. Open, two adjacent movable circular arc plates 1 are connected by hinges 10, the rear end of the middle movable circular arc plate 1 is connected to the inner wall of the inner draft tube 7 through a fixed hinge, th...

Disclosed is an air power distribution and regulation mechanism of a fan of a hovercraft. An inner flow guide pipe is arranged inside an outer flow guide pipe; the inner flow guide pipe is formed by four circular arc plates which are divided into a fixed circular arc plate and three flexible circular arc plates; the fixed circular arc plate is connected with every flexible circular arc plate through an extensible hinge; every two adjacent flexible circular arc plates are connected with each other through a hinge; the rear end of the middle flexible circular arc plate is connected with the inner wall of the inner flow guide pipe through a fixed hinge; the front end of the middle flexible circular arc plate is connected with one end of an ejector rod; the other end of the ejector rod is fixed on the outer flow guide pipe; a fan hub body is arranged inside the inner flow guide pipe. The movement of the circular arc plates is regulated so as to reduce the backward fan power outlet area and meanwhile increase the fan power outlet area towards the bottom and accordingly the thrust can be increased during high speed and the controllable hover effect of the hovercraft is implemented. The hover height is controlled by the air power distribution and regulation mechanism of the fan of the hovercraft by an air flow distribution method and accordingly the use performance of the hovercraft is improved.
Description
[0001] Technical field: [0002] The invention relates to the technical field of regulating aerodynamic flow direction, in particular to a hovercraft fan aerodynamic distribution regulating mechanism. [0003] Background technique: [0004] In order to reduce the weight of the hovercraft itself, simplify the number of equipment, combine the functions of the equipment, and improve the reliability of the equipment, the technology of the propulsion and pad lift of the hovercraft has undergone major changes. Traditionally, the fans used for propulsion and pads are used The two sets of relatively independent devices consisting of liter fans have tended to only have one set of fans to undertake the dual functions of propulsion and lift. However, the aerodynamic force generated by the fan usually has a fixed outlet area backward and towards the bottom of the ship, which brings about the problem that the lift power cannot be adjusted under a certain constant condition of the main engin...
