The invention relates to a system device adopting a vector thrust technology and a heavy-load electric vertical take-off and landing aircraft (eVTOL) adopting a power redundancy design. A vector thrust technology system device is composed of one or more sets of direct-current servo electric cylinder systems or direct-current servo motor gear transmission systems on the two sides of the interior of an aircraft fuselage, and rotation of a main shaft of a wing (fixed wing) is accurately controlled by means of the closed-loop control principle of a servo motor. And the whole composite wing (all fixed wings and a multi-rotor wing group) is driven to realize synchronous full tilting and accurate positioning of each angle in a range of +/-90 degrees, and finally, the flexible conversion of various flight attitudes such as vertical take-off and landing, level flight cruising, climbing and glide landing of the aircraft is realized. In the aspect of power redundancy design, according to different load capacities, the power redundancy design can be divided into a single-seat plate of 8 front and rear rotor propellers, a double-seat plate of 12 front and rear rotor propellers, and a three-seat or multi-seat plate of 16 front and rear rotor propellers. Four groups, six groups and eight groups of independent power propulsion systems can be respectively arranged on each type of aircrafts, and 1-2 groups or even more than 3 groups of independent power propulsion systems can be finally redundant, so that more powerful safety guarantee is provided for air flight of the aircrafts. Through a vector thrust technology system device and a power redundancy design, the aircraft eVTOL can further reduce the energy consumption, improve the flight efficiency, improve the flight speed, performance, endurance time, mileage and the like, and greatly improve the flight safety of the aircraft type.

    本发明涉及一种采用矢量推力技术系统装置,以及动力冗余设计的大载重电动垂直起降飞行器(eVTOL)。矢量推力技术系统装置,由飞行器机身内部两侧的一至多套直流伺服电动缸系统或直流伺服电机齿轮传动系统共同组成,利用伺服电机的闭环控制原理,精准控制机翼(固定翼)主轴的旋转,并带动整个复合翼(全部固定翼+多旋翼翼组)在±90度范围内实现各角度的同步全倾转与精准定位,最终实现飞行器的垂直起降、平飞巡航,以及爬升、滑降等多种飞行姿态的灵活转换。在动力冗余设计方面,根据载重量的不同,可分为前4后4共8个旋翼桨的单座版、前8后4共12个旋翼桨的双座版,以及前8后8共16个旋翼桨的三座或多座版。各型机可分别设置出4组、6组、8组独立的动力推进系统,并最终能够冗余1‑2组,甚至冗余3组以上,为本机空中飞行提供更强大的安全保障。通过矢量推力技术系统装置,以及动力冗余设计,该种飞行器eVTOL可以进一步降低能耗、改善飞行效率,提高其飞行速度、性能及续航时间、里程等,并极大地提升该种机型的飞行安全性。
