    • A rotor system of a rotary wing aircraft, e.g. a helicopter with a rotor mast, a rotor hub (1), at least four, angularly essentially even distributed rotor blades (2, 3) and swash plate struts (15) for pitch and subsequently flap control. Said rotor blades (2, 3) are respectively pairwise mounted lag- and flap-stiff to each other with zero offset to said rotor hub (1). The rotor hub (1) is provided with a hollow bearing (20) with at least one further bearing inside (21), a first pair of said rotor blades (2) is mounted on the hollow bearing pivotable in a first flap direction (23) essentially perpendicular to said rotation axis, and at least a second pair of said rotor blades (3) is mounted inside the hollow bearing (20) on the at least one further bearing (21) pivotable in a second flap direction (22) substantially perpendicular to said first flap direction (23) and said rotation axis, and independently of said first pair of connected rotor blades (2).
    • 旋翼飞机的转子系统,例如 具有转子桅杆的直升机,转子轮毂(1),至少四个角度基本均匀分布的转子叶片(2,3)和斜盘支柱(15),用于俯仰和随后的挡板控制。 所述转子叶片(2,3)分别成对地相对于所述转子毂(1)以零偏移彼此成对地相对于所述转子叶片彼此成对安装。 转子轮毂(1)设置有在内部具有至少一个其它轴承的中空轴承(20),第一对所述转子叶片(2)安装在中空轴承上,该第一翼片方向(23) )基本上垂直于所述旋转轴线,并且至少第二对所述转子叶片(3)安装在所述中空轴承(20)内的所述至少一个另外的轴承(21)上,所述至少一个另外的轴承(21)可基本上在第二挡板方向(22) 垂直于所述第一翼片方向(23)和所述旋转轴线,并且独立于所述第一对连接的转子叶片(2)。
