Cross-medium aircraft with changeable shape like sailfish

Abstract

Provided is a cross-medium aircraft with a changeable shape like a sailfish. The streamline type appearance of the sailfish is simulated by a machine body (2). A head pointed cone (1) is arranged at the head portion of the machine body (2) to divide water flow. A pair of angle-changeable water wings (3) are installed on the two sides of the front portion of the machine body (2) respectively. The aircraft is controlled to sink or float in water by adjusting the positive tapping angle and the negative tapping angle of the pair of angle-changeable water wings (3). A pair of scale-shaped rectifying covers are installed on the two sides of the middle of the machine body (2) respectively. A pair of self-adaption spiral paddles (4) capable of rotating in an inclined mode are installed on the scale-shaped rectifying covers (5) through a pair of spherical multi-freedom-degree linkage steering gears (6). An X-shaped tail wing (7) is arranged at the middle rear section of the machine body (2). An underwater-propulsion spiral paddle (8) is installed at the tail portion of the machine body (2). By means of the cross-medium aircraft, the design principles and bionics principles of the aircraft and an autonomous underwater vehicle are successfully applied, and the designed cross-medium aircraft has the good running capacity in fluid of two different types including air and water.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a bionic deformation trans-medium aircraft. 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 submarines, surface ships ...

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.
