Amphibious aircraft

Abstract

The invention discloses an amphibious aircraft which comprises an aircraft body, wings, short engine compartments, floating barrels, an empennage and an undercarriage. The wings are fixed to a hump onthe back of the aircraft body. The short engine compartments are installed at the head ends of the wings. The floating barrels are arranged on the two sides of the middle portion of the aircraft bodyand located below the wings. The empennage is arranged on the tail portion of the aircraft body. The undercarriage is installed at the bottom end of the aircraft body. The floating barrels are provided with protrusions, and containing cavities with openings are formed in the leeward faces of the protrusions. It can be guaranteed that when the aircraft glides at a high speed on the water surface,the longitudinal and transverse stability and the water surface take-off and landing performance are good, and the stability of the aircraft in the flight process is improved as well.

Description

technical field [0001] The invention relates to an aircraft, more specifically relates to an amphibious aircraft, and belongs to the technical field of manned aircraft. Background technique [0002] In recent years, the requirements for high-speed, reliability and multi-environmental adaptability of surface and near-water vehicles have become higher and higher. Therefore, amphibious aircraft has become a research hotspot. The traditional amphibious aircraft consists of a fuselage and an inflatable air cushion, which can meet the operation and take-off and landing of various environments such as water, land, and tidal flats. However, it has poor adaptability in high sea conditions, and the body moves violently in wind and waves. Poor, the take-off and landing process is risky, and it is difficult to maintain high-speed navigation; at the same time, due to the violent movement of the aircraft in the wind and waves, the gas in the air cushion at the bottom of the aircraft is ea...

The traditional amphibious aircraft consists of a fuselage and an inflatable air cushion, which can meet the operation and take-off and landing of various environments such as water, land, and tidal flats. However, it has poor adaptability in high sea conditions, and the body moves violently in wind and waves. Poor, the take-off and landing process is risky, and it is difficult to maintain high-speed navigation; at the same time, due to the violent movement of the aircraft in the wind and waves, the gas in the air cushion at the bottom of the aircraft is easy to overflow, and the pressure of the air cushion changes drastically, which has a great impact on safety
