The invention discloses a high-speed tilting four-rotor aircraft. The high-speed tilting four-rotor aircraft comprises wings, longitudinal beams and power cabins, the power cabin is arranged above the middle of the fuselage, and the wings are arranged on two sides of the power cabin; the wings on the two sides of the power cabin are each provided with a longitudinal beam in the longitudinal direction of the fuselage, the end of each longitudinal beam is provided with a rotor wing through a pivot, and the pivots can drive the rotor wings to rotate relative to the longitudinal beams; the two engines are arranged in a power cabin at the top of the middle fuselage side by side; output shafts of the engines are connected with an input stage of the main speed reducer; and the torque provided by the output stage of the main speed reducer is finally used for driving the rotor wings. Compared with the prior art, the unmanned aerial vehicle provided by the invention has the advantages of fewer engines, simpler flight control system, lower vibration and noise level, weight and cost advantages, superior fuel economy and larger voyage endurance.
本发明公开了一种高速倾转四旋翼飞行器,包括机翼,纵梁以及动力舱;动力舱布置在机身中部上方,机翼布置在动力舱的两侧;在动力舱两侧的机翼上沿机身纵向各布置一个纵梁,每个纵梁的端部通过枢轴安装一个旋翼,枢轴能带动旋翼相对于纵梁转动;两台发动机并排安装在中机身顶部的动力舱内,发动机的输出轴与主减速器的输入级连接;主减速器的输出级提供的扭矩最终用于驱动所述旋翼。相比于现有技术,本发明具有更少的发动机数量、更简单的飞控系统、更低的振动、噪声水平,并具有重量及成本优势、优越的燃油经济性,更大的航程航时。
