The invention belongs to the technical field of helicopter design, and relates to a helicopter with a variable distance between a main rotor and a tail rotor. The helicopter comprises a fuselage (100), a variable-length tail beam (200), the main rotor (300), the tail rotor (400) and an undercarriage (500), the main rotor (300) is located right above the fuselage (100), the undercarriage (500) is located below the fuselage (100), the variable-length tail beam (200) is arranged between the fuselage (100) and the tail rotor (400), and the distance between the main rotor (300) and the tail rotor (400) can be adjusted. The transmission-free tail rotor helicopter with the variable tail beam length has the advantages of high hovering efficiency, strong crosswind resistance, high forward flight aerodynamic efficiency and the like.

    本发明属于直升机设计技术领域,具体涉及一种主旋翼与尾桨间距可变的直升机。包括机身(100)、可变长度尾梁(200)、主旋翼(300)、尾桨(400)、起落架(500);所述主旋翼(300)位于所述机身(100)正上方,所述起落架(500)位于所述机身(100)下方,所述可变长度尾梁(200)设置于所述机身(100)与所述尾桨(400)之间,可实现所述主旋翼(300)与所述尾桨(400)间距的调节。这种可变尾梁长度的无传动尾桨直升机具有悬停效率高、抗侧风能力强和前飞气动效率高等优点。
