    • A helicopter 10 with a system for controlling mainrotor torque which reduces the power and size requirements of conventional anti-torque means. The torque countering forces are generated by disrupting the main rotor downwash flowing around the fuselage. The downward flow is separated from the fuselage surface 11 by strakes 16 and 17 positioned at specified locations on the fuselage 11. These locations are determined by the particular helicopter wash pattern and fuselage configuration, generally being located 30.degree. before top dead center 21 and 30.degree. from bottom dead center 22 on the fuselage side to which the main rotor blade 12 approaches during rotation. The strakes 16 and 17 extend along the fuselage 11 from the cabin section 18 to the aft end and can be continuous or separated for aerodynamic surfaces such as a horizontal stabilizer 15.
    • 具有用于控制主旋翼扭矩的系统的直升机10,其降低了常规抗扭矩装置的功率和尺寸要求。 力矩对抗力是通过扰乱机身周围流动的主转子下冲而产生的。 向下的流动通过位于机身11上的特定位置处的行星架16和17与机身表面11分离。这些位置由特定的直升机洗涤图案和机身构造确定,通常位于上止点21和30之前30° DEG在主转子叶片12在转动时接近的机身侧的下死点22。 横带16和17沿着机身11从机舱部分18延伸到后端,并且可以连续地或分开用于诸如水平稳定器15的空气动力学表面。
