Embodiment Construction

[0015] The present invention comprises a fuselage 1, a wing 2, a pair of canards 3, flaps, ailerons, an air-propelled foldable propeller 4, an empennage 5, an underwater propulsion propeller 6 and a fairing 7, and the fuselage 1 is streamlined in imitation of a flying fish Fuselage, and a pair of wings 2 and a pair of canards 3 form a combined wing that imitates the shape layout of the pectoral fins of flying fish. The wings 2 are movably installed on both sides of the middle part of the fuselage 1, and a pair of canards 3 are respectively installed under the middle and rear of the fuselage 1. The wings 2 and the canards 3 can rotate around their respective rotation axes to change the angle of attack. Angle, when diving underwater, the aircraft is controlled to float or dive by adjusting the positive and negative angles of attack of the wings 2 and canards 3. The flaps and ailerons are respectively arranged on the inside and outside of the wings 2, and the foldable propeller 4 ...

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 ...
