A shell structure of a trans-medium aircraft and the aircraft

Abstract

The invention discloses a medium-span aircraft shell structure and an aircraft and relates to the field of underwater high-speed flying. The medium-span aircraft shell structure comprises a head cabinsection, a main body cabin section as well as a hydrophilic coating and a lyophobic coating, wherein the hydrophilic coating is arranged on the lower surface of the main body cabin section; and the outer surface of the lyophobic coating is covered by the head cabin section. According to the medium-span aircraft shell structure and the aircraft disclosed by the invention, asymmetric vacuoles of asymmetric design are adopted for passive control on underwater postures of the aircraft, the shape of the head cabin section is not particularly required, and in addition, a control device and an execution device are not additionally needed, so that the appearance design requirements on aircraft shells are reduced, and the medium-span aircraft shell structure is low in production cost, good in controllability and reliability and good in engineering application prospect.

Description

technical field [0001] The invention relates to the field of underwater high-speed navigation, in particular to a shell structure of a trans-medium aircraft and the aircraft. Background technique [0002] Water-entry cross-media aircraft usually enter the water from the air at a relatively high flight speed, and the aircraft will be subject to a large impact, resulting in water-entry cavitation. The stability of the aircraft when entering water. [0003] At present, the stability of the aircraft entering the water is mainly improved by changing the shape of the head of the trans-media aircraft, such as cone, spherical, flat top, etc.; or the stability of the aircraft entering the water is improved by pre-setting the rotation and tilt of the aircraft before entering the water. [0004] The method of changing the shape of the head requires extremely high requirements for the shape design of the aircraft shell, and even affects the layout of the aircraft's head components; the...

Problems solved by technology

[0004] The method of changing the shape of the head requires extremely high requirements for the shape design of the aircraft shell, and even affects the layout of the aircraft's head components; the method of pre-setting the rotation and tilt of the aircraft before entering the water requires a separate control mechanism and actuator. It not only increases the cost of R & D and production, but also when the controller fails, the rotation and tilt cannot be performed, the control is difficult and the reliability is low
