Aircraft sheet-shaped fuselage body

Abstract

The invention discloses an aircraft sheet-shaped fuselage body, belonging to the technical field of aircraft and bionic engineering. The height and the length of the aircraft sheet-shaped fuselage body are much greater than the width, the ratio of height to width and the ratio of length to width are greater than or equal to 2, the aircraft sheet-shaped fuselage body may be an integral structure or a combined structure of a cabin and a flow guide plate, and the flow guide plate is a continuous surface structure. The aircraft sheet-shaped fuselage body can be freely laid out in the height direction and the length direction, after use, the aircraft sheet-shaped fuselage body can thoroughly solve the contradiction that two aerodynamic requirements of vertical take-off and landing and high-speed flat flight are hard to combine in the fuselage design, center of gravity of an aircraft is significantly reduced, wind resistance ability is greatly improved, and the aircraft sheet-shaped fuselage body has autoadaptive capacity. The aircraft sheet-shaped fuselage body has distinctive advantages of coordinated flight mechanism, low gravity, good stability, strong wind resistance, good flexibility, easy operation, high safety, strong applicability and the like, also has the advantages of simple structure, reliable performance, convenient operation, and low purchase cost and use cost, and is suitable for public use.

Description

technical field [0001] The invention relates to an aircraft fuselage structure, in particular to an aircraft sheet fuselage, which belongs to the technical field of aircraft. Background technique [0002] According to different geometric shapes, aircraft fuselage can be roughly divided into four types: columnar, spherical, plate-shaped (flying wing) and spherical + plate-shaped. The aircraft with a spherical fuselage (such as a helicopter) has a large wind resistance and can fly vertically and horizontally. The two modes interfere with each other, and in severe cases, "½ P jump" occurs; and the engine is arranged on the upper part of the fuselage, the center of gravity is high, and the stability of the vertical lift and horizontal flight mode conversion process is poor; and the simple superposition of the two flight principles results in poor coordination of the flight mechanism , the mechanism is complicated, the control is difficult, and the maneuverability is poor; there ...

[0002] According to different geometric shapes, aircraft fuselage can be roughly divided into four types: columnar, spherical, plate-shaped (flying wing) and spherical + plate-shaped. The aircraft with a spherical fuselage (such as a helicopter) has a large wind resistance and can fly vertically and horizontally. The two modes interfere with each other, and in severe cases, "½ P jump" occurs; and the engine is arranged on the upper part of the fuselage, the center of gravity is high, and the stability of the vertical lift and horizontal flight mode conversion process is poor; and the simple superposition of the two flight principles results in poor coordination of the flight mechanism , the mechanism is complicated, the control is difficult, and the maneuverability is poor; there is also a lack of unpowered forced landing measures, the accident survival rate is low, the interference is serious, and the efficiency is not high

The plate-shaped body aircraft (such as B-2, F-117 and other flying wing aircraft) is not suitable for vertical take-off and landing, pitch control is difficult, and the stability is poor

Cylindrical fuselage aircraft (such as various common fixed-wing aircraft) require runway run-ups to take off and land at high speeds, which are expensive, have limited take-off and landing sites and weather conditions, and have high carbon emissions, making it difficult to popularize
