Large-length-width-ratio hull of amphibious aircraft

Abstract

According to the amphibious aircraft hull with the large length-width ratio, the wave motion response is reduced by using the amphibious aircraft hull with the large length-width ratio and the long afterbody, and the sea wave adaptability of the amphibious aircraft is improved. The large-length-width-ratio ship body comprises a front body and a rear body, the contact points of the large-length-width-ratio ship body and waves are increased, the restoring moment is increased, the overturning moment is reduced quickly, the long rear body design is adopted, the rear body is longer than the front body, the wave contact area of the rear body is large, the hydrodynamic lift force of the rear body is large, and the head-up moment of an aircraft is reduced. According to the large-length-width-ratio ship body of the amphibious aircraft, unstable movement such as jumping is not prone to being generated in waves, the pitching movement amplitude, the heaving amplitude and overload borne by the aircraft body can be reduced through the large-length-width-ratio ship body, and the large-length-width-ratio ship body of the amphibious aircraft is simple in structure and can be suitable for the large amphibious aircraft.

Description

technical field [0001] The invention belongs to the field of amphibious aircraft hull design, and in particular relates to an amphibious aircraft hull with a large aspect ratio. Background technique [0002] When an amphibious aircraft takes off and lands in waves, it will produce coupling motions such as pitching and lifting, and the body structure will bear a certain overload. If the pitch amplitude exceeds the safe range of the amphibious aircraft, the aircraft will lose control, or the overload on the body will be too large. The deformation or damage of the body is directly related to the safety of the amphibious aircraft. [0003] For this reason, it is necessary to reduce the motion response in waves, improve the anti-wave capability of the amphibious aircraft, and improve the wave adaptability of the amphibious aircraft. At present, there is no amphibious aircraft hull with high adaptability to waves. Contents of the invention [0004] The invention provides a hull...
