Abstract

The invention discloses a water-air amphibious annular wing aircraft based on thrust vector nozzles and a navigation control method of the water-air amphibious annular wing aircraft. The water-air amphibious annular wing aircraft comprises an annular wing layout fuselage and a thrust vector power device array. The fuselage is jointly formed by different airfoils, adopts a control-surface-free design, is suitable for air flight / underwater navigation, is compact in structure, small in navigation resistance and good in stability, and can vertically take off and land; four thrust vector power units are arranged on the annular wing layout fuselage in an X shape with equal arc length, can propel the aircraft in a water / air medium, and replace a control surface to complete attitude control of the aircraft; each thrust vector power unit comprises an air inlet / water inlet channel, an engine, a thrust vector nozzle and related control and servo mechanisms. The control-surface-free high-efficiency water-air navigation can be completed by using a set of fuselage and a power device, and the application scene of the aircraft is greatly widened.

Description

technical field [0001] The invention relates to the technical field of ring-wing aircraft, in particular to a water-air amphibious ring-wing aircraft based on a thrust vectoring nozzle and a navigation control method thereof. Background technique [0002] With the continuous development of aircraft and aircraft technology, it is increasingly difficult for a single-function aircraft to meet various needs in military and civilian fields. In the military field, an amphibious vehicle that can fly in the air and dive underwater can realize infrared and radar stealth with the help of water, that is, it has water shielding, which makes it easier to realize tactical suddenness, making its combat methods flexible and changeable. To a certain extent, it adapts to the increasingly "multi-dimensional" and "integrated" complex battlefield environment; in the civilian field, due to its amphibious characteristics of water and air, it can have a wider range of application scenarios in scien...
