The invention discloses a dual variable united wing aircraft with variable wings; the number of the front wings and the number of the rear wings are both two, the front ends of the two front wings are hinged to each other to form a front intersection point, and the rear ends of the two rear wings are hinged to each other to form a rear intersection point. The middle of each front wing is hinged to the middle of the corresponding rear wing to form a left intersection point and a right intersection point, telescopic wings are arranged in the fuselage, each telescopic wing is provided with two telescopic ends, one telescopic end of each telescopic wing is connected with the left intersection point, and the other telescopic end of each telescopic wing is connected with the right intersection point. The front intersection point and the rear intersection point are slidably connected to the fuselage. The aircraft has the advantages that the wings can well adapt to different flight speeds, redundant lift force is reduced as much as possible, the weight of a mechanical structure is reduced, the lift force for slow takeoff is increased, resistance for high-speed flight is reduced, the gravity center and the lift force center of the aircraft are not changed when the sweep angles of the wings are changed, flight control difficulty is reduced, the structural weight of the aircraft is reduced, and aerodynamic layout is improved.
本发明公开了一种具有可变机翼的双可变联翼飞行器,前翼和后翼均为两个,两个前翼的前端相互铰接形成前交叉点,两个后翼的后端相互铰接形成后交叉点,每个前翼的中部分别与对应的后翼中部之间相互铰接形成左交叉点和右交叉点,伸缩翼设置在机身内,伸缩翼具有两个伸缩端,伸缩翼的一个伸缩端与左交叉点连接,伸缩翼的另一个伸缩端与右交叉点连接,前交叉点以及后交叉点均分别滑动连接在机身上。达到的技术效果为:可以使机翼很好地适应不同的飞行速度,尽量减少多余的升力、减少机械结构重量、增加慢速起飞的升力、减少高速飞行的阻力,改变机翼掠角时并不改变飞机重心和升力心,减少飞控难度,减轻飞机结构重量、改善气动布局。
