The vertical take-off and landing fixed-wing aircraft comprises a fuselage, a front wing and an empennage which are sequentially connected to the fuselage in the length direction of the fuselage front and back, and a plurality of groups of drivers which are arranged on the front wing and the empennage respectively to provide driving force. The driver connected to the front wing is a coaxial contra-rotating propeller fan driver with two rows of contra-rotating propeller blades which are coaxially arranged front and back, and the driver connected to the empennage is a coaxial contra-rotating propeller fan driver or a single-row propeller fan driver with only one row of rotatably arranged propeller blades. The coaxial contra-rotating propeller fan drivers and the single-row propeller fan drivers are arranged in a tilting mode along the vertical plane so as to provide driving force for forward flight, vertical take-off and landing and hovering of the aircraft. According to the aircraft, the propeller blade propelling efficiency can be improved, and under the same driving force, compared with a single-row propeller driver, the radius of the propeller plane of the coaxial contra-rotating propeller fan driver is smaller, so that the wingspan of a main wing can be effectively shortened, and the space occupied area and the size of the aircraft are reduced.
本发明公开了一种垂直起降固定翼飞行器,包括:机身、沿机身的长度方向前后依次连接于机身上的前翼和尾翼、多组分设于前翼和尾翼上以提供驱动力的驱动器。连接于前翼上的驱动器为具有前后同轴设置的两排对转桨叶的同轴对转桨扇驱动器,连接于尾翼上的驱动器为同轴对转桨扇驱动器或为仅具有一排转动设置的桨叶的单排桨扇驱动器。同轴对转桨扇驱动器和单排桨扇驱动器均沿竖直平面倾转设置,以供给飞行器向前飞行、垂直起降、空中悬停的驱动力。本发明的飞行器,可提高桨叶推进效率,并产生相同驱动力下,相比单排桨驱动器,本发明的同轴对转桨扇驱动器的桨平面的半径更小,从而可有效缩短主翼的翼展,减少空间占用面积和飞行器尺寸。
