Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The retractable apron structure of the amphibious aircraft of the present invention comprises an apron structure and a retracting capsule device, the apron structure comprises an arc-shaped rigid surface and a flexible capsule, the arc-shaped rigid surface is hinged with the hull, and the flexible capsule is connected to the arc Rigid surface of the shape and hinged connection at the bottom of the hull. The recovery capsule device includes a steel wire rope, a miniature electric hoist and a connector. The miniature electric hoist is fixed on the top of the air chamber, and the connector buckle is fixed on the capsule. After the wire rope passes through the connector, Secure the two strands of wire rope with another wire rope buckle.

[0021] The characteristics of the above-mentioned technical scheme are: when the amphibious ai...

Abstract

The invention provides a retractable apron structure of an amphibious aircraft. The retractable apron structure comprises an apron structure and a capsule body retracting device. The apron structure comprises an arc-shaped rigid surface and a capsule body, wherein one end of the arc-shaped rigid surface is hinged to a hull, the other end of the arc-shaped rigid surface is hinged to the capsule body, the capsule body is further hinged to the bottom of the hull, and an exhaust hole channel is arranged at the joint between the capsule body and an air chamber. The capsule body retracting device comprises a connecting rope, a miniature electric hoist and a connecting piece, wherein the miniature electric hoist is arranged at the top end of the air chamber, the connecting piece is arranged on the capsule body, the connecting piece is connected to one end of the connecting rope, and the miniature electric hoist is connected to the other end of the connecting rope. The retractable apron structure of the amphibious aircraft is simple in structure, easy to operate and convenient to inspect and maintain, and can well adapt to two working conditions of an air cushion aircraft, the response ofthe apron structure is higher during sailing at sea, and the seakeeping is good; and the retractable apron design can reduce the flying resistance during flying, and the air cushion aircraft is enabled to have better navigation performance.

Description

technical field [0001] The invention relates to an amphibious aircraft, in particular to a retractable apron structure of an amphibious aircraft. Background technique [0002] Due to the excellent amphibious capability of amphibious aircraft, it can play an irreplaceable role in other means of transportation in terms of forest fire fighting, water rescue, and economic development. Therefore, how to improve the rapidity, stability and multi-environmental adaptability of amphibious aircraft has become a research hotspot in recent years. A conventional amphibious aircraft consists of a fuselage and an air cushion system. The air cushion system can be divided into closed type without bag and non-closed type with bag. The non-enclosed type means that the closed type maintains an inflated state when flying in the air, which is beneficial to flight stability, but has poor seakeeping when sailing on the water surface; while the non-enclosed type means that the non-enclosed type ha...
