Embodiment Construction

[0028] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0029] 1. Seaplane float design;

[0030] According to the requirements of "Part 23 of the Civil Aviation Regulations of China" on the buoyancy of buoys, refer to the design of relevant buoys, and then estimate the relevant parameters of the buoys (including width B, height H, front body length, rear body length, total length L, volume V). The sketch of the cross-section at the step of the buoy is as follows: figure 1 As shown, the three-dimensional shape of the buoy is as follows figure 2 shown.

[0031] 2. Seaplane float baffle design:

[0032] In order to reduce the aerodynamic resistance, the pontoon baffle is designed to be skin-fitted and hinged to the edge of the upper wall of the pontoon. A torsion spring (return spring) is placed on the rotating shaft of the water baffle, and the torque applied by the torsion spring is smaller than that applie...

Abstract

The invention discloses an automatic splash-proof float, aiming at solving the problem of splash of a seaplane with a non-hull body in a stern thrust mode. The automatic splash-proof effect in the process of taking off or landing of the plane on the water surface is achieved. According to the implementation mode, a water inlet chamber is formed in the tail of the float; water wheels in the water inlet chamber are driven by power generated by water flow in the process of taking off or landing of the plane, and a skin type water baffle which is tightly attached to the seaplane float is pushed open by the water wheels by virtue of a chain wheel transmission device and an opening / closing device; and after the process of taking off or landing of the plane is finished, thrust generated by the water flow disappears, and the water baffle resets under the action of a spring and returns to an initial position of the tightly attached float. The opening / closing device of the water baffle is automatically realized through two modes. According to the automatic splash-proof float disclosed by the invention, the problem of influence of water splash generated in the process of taking off or landing of the seaplane with the non-hull body in the stern thrust mode on a power device system can be greatly solved. According to an automatic opening and closing mechanism, the adaptive function is simply and reliably realized, and the automatic splash-proof float has a certain application and popularization in the field of aviation and related fields.

Description

technical field [0001] The invention relates to the field of water surface take-off and landing aircraft, or the design field of water surface movement machinery, in particular to an automatic splash-proof seaplane buoy. Background technique [0002] 1. The water splash generated by the takeoff and landing of the seaplane will have different degrees of impact on the aircraft power system, and the size of the impact depends on the layout of the seaplane. For aircraft with a conventional layout at the front of the engine, the water splash will hardly fall on the propeller and engine, while the seaplane with the rear engine usually uses a hull to dispel the water. However, the hull and fuselage will increase the structural weight of the aircraft, and the increase in the surface area of ​​the aircraft and the change of the conventional fuselage section will also increase the aerodynamic drag accordingly, resulting in a decline in aircraft performance (such as range, maximum flig...
