The invention relates to the technical field of aircrafts, in particular to a double-fuselage cross rotor aircraft which is of a symmetrical structure and comprises a first fuselage, a second fuselage and wings, a first rotor system is arranged in the middle of the top of the first fuselage, and a second rotor system is arranged in the middle of the top of the second fuselage; a first propelling system and a second propelling system are arranged on the wings; a vertical empennage structure is arranged between the tails of the first fuselage and the second fuselage, a first landing gear is arranged at the bottom of the first fuselage, and a second landing gear is arranged at the bottom of the second fuselage. The cross rotors enable the aircraft to have vertical take-off and landing and hovering capacities, the wind resistance is improved, the double-fuselage layout type of the first fuselage and the second fuselage facilitates arrangement of high-aspect-ratio wings, the loading capacity and the cruising efficiency of the aircraft are improved, and the aircraft is suitable for large-scale popularization and application. The problems of shock waves of forward blades and stalling of backward blades of rotor wings when a conventional helicopter flies forward are solved, and the helicopter has high-speed cruise performance, is of a symmetrical structure on the whole and is good in operation stability.
本申请涉及飞行器技术领域,且涉及一种双机身交叉旋翼飞行器,为对称式结构且包括第一机身、第二机身和机翼,第一机身的顶部中间设置有第一旋翼系统,第二机身的顶部中间设置有第二旋翼系统;机翼上设置有第一推进系统和第二推进系统;第一机身和第二机身的尾部之间设置有平垂尾翼结构,第一机身的底部设置有第一起落装置,第二机身的底部设置有第二起落装置。本申请中交叉旋翼使飞行器具备垂直起降和空中悬停能力,提高抗风性能,第一机身和第二机身的双机身布局型式,有利于布置大展弦比机翼,提高飞行器的载重能力和巡航效率,改善常规直升机前飞时旋翼前行桨叶激波和后行桨叶失速问题,具备高速巡航性能,整体为对称式结构,操稳特性较好。
