Cross-medium aircraft with changeable shape like flying fish

Abstract

Provided is a cross-medium aircraft with a changeable shape like a flying fish. A pair of machine wings (2) are movably installed on the two sides of the middle of a machine body (1) respectively. A pair of duck wings (3) are installed below the middle rear portion of the machine body (1). The machine wings (2) and the duck wings (3) can rotate around rotating shafts to change the tapping angle. A flap and an aileron are distributed on the inner side and the outer side of each machine wing (2) respectively. An air-propulsion foldable spiral paddle (4) is installed at the head portion of the machine body (1). A V-shaped tail wing (5) is arranged at the middle rear section of the machine body (1). An underwater-propulsion spiral paddle (6) is installed at the tail portion of the machine body (1). A rectifying cover (7) is arranged at the lower middle portion of the head of the machine body (1). The cross-medium aircraft has the advantages that the air-water dynamic layout of two different media including air and water and the light pressure-resistant shape-changeable structure are taken into consideration, multi-mode control and water sealing can be easily achieved, and the various military and civilian requirements can be met.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a flying fish-like cross-medium aircraft with a variable configuration. Background technique [0002] At present, the cross-media new concept aircraft is a multi-functional integrated new equipment that can fly in the air, fly near the water surface, and dive underwater. The working modes of the aircraft can be divided into air flight mode, near water surface flight mode, entry and exit water surface mode and underwater sneak mode, which can be switched between various work modes according to mission requirements. [0003] Cross-media manned aircraft can use the blind spots of various detection equipment to switch sea and air operation modes to avoid enemy surveillance, and realize "stealth" operations in an unconventional way, and can be used to perform tasks such as maritime reconnaissance, strikes, and special force projection. Cross-media unmanned aerial vehicles can be matched with ...

AI Technical Summary

Problems solved by technology

However, due to the wide range of professional fields covered by the core technology of cross-media aircraft and the high technical difficulty, especially when it comes to the design part of underwater navigation, there is a big difference from aircraft design, mainly in layout, structure, power, control and water seal design. At present, domestic and foreign research in this field is basically still in the stage of overall conceptual design, key technology research and prototype verification, and no country has successfully developed products with engineering practical value.
