Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0030] 1. Seaplane float design;

[0031] According to the requirements of "Part 23 of the Civil Aviation Regulations of China" on the buoyancy of buoys, refer to the design of the relevant buoys, and then estimate the overall dimensions of the buoys (including the 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.

[0032] 2. Seaplane float 1 design:

[0033] In order to reduce the aerodynamic resistance, the water baffle 1 of the buoy is designed as a skin-fitting form, and is hinged with the edge of the upper wall of the buoy. A return spring 17 is arranged on the rotating shaft 9 of the water deflector 1, and the torque applied by the return spring 17 is small...

Abstract

The present invention proposes an automatic waterproof splash buoy to solve the problem of water splash in a non-hull fuselage seaplane in the form of a tail push, and achieves the effect of automatic waterproof splash during the takeoff and landing process of the aircraft. The realization method is to set up a water inlet cabin at the tail of the buoy, and drive the water wheel in the water inlet cabin by the power generated by the water flow during take-off and landing. Leather flap; after take-off or landing, the thrust generated by the water flow disappears, and the flap automatically returns to the initial position close to the buoy under the action of the return spring. The opening and closing device of the water baffle is automatically realized in two ways. The invention can solve to a greater extent the problem of the influence on the power plant system caused by the splash generated by the tail-propelled non-hull fuselage seaplane during take-off and landing. Among them, the automatic opening and closing mechanism realizes the self-adaptive function simply and reliably, and has certain application and promotion in the aviation field 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...
