    • The invention provides a method of dynamically alleviating loads generated on an aircraft (2) by a disturbance of gust and/or turbulence, the method comprising the steps of:
      on a flight of the aircraft (2), a monitoring is applied for automatically detecting a disturbance due to gust and/or turbulence and determining an incidence angle of the disturbance;
      when a disturbance due to gust and/or turbulence is detected, automatically generating control commands (36; 32, 38, 40, 42) for deflecting control surfaces dependent on the incidence angle; and
      applying the control commands (36; 32, 38, 40, 42) to deflect the control surfaces.
      For optimizing the performance, it is proposed to conduct at least one of the following step sequences A) and/or B):
      A) adapting the control commands (36; 32, 38, 40, 42) not only to the amount of the incidence angle but also to the gust length in order to adapt the deflection of the control surfaces both to the incidence angle and the gust length; and/or
      B) generating first control commands (y, 34; 32, 38) for first control surfaces and second control commands (36; 32, 38, 40, 42) for second control surfaces, comparing the incidence angle with a predetermined value and generating the first control commands (y, 34; 32, 38) to actuate the first control surface until the incidence angle reaches this predetermined value and generating the second control commands (36; 32, 38, 40, 42) to add a deflection of the second control surfaces when the incidence angle is above the predetermined value.
    • 本发明提供由阵风和/或湍流的干扰产生的到飞行器(2)动态地减轻负载的方法,包括以下步骤的方法:在飞行器的飞行(2),监视被应用于自动地检测 由于干扰阵风和/或紊流和在扰动的入射角确定的开采; 当由于干扰向阵风和/或检测到的湍流,自动地生成的控制命令(36; 32,38,40,42)用于偏转依赖于入射角控制表面; 以及将所述控制命令(36; 32,38,40,42)以偏转控制表面。 为了优化性能,所以建议进行下列步骤序列A)和/或B)中的至少一个:A)适应的控制命令(36; 32,38,40,42)不仅要的量 入射角但所以为了适应控制表面两者的入射角和阵风长度的偏转阵风长度; 和/或B)产生第一控制命令(Y,34; 32,38),用于第一控制表面和第二控制命令(36; 32,38,40,42),用于第二控制表面,入射角与预定值进行比较 和产生所述第一控制命令(Y,34; 32,38)来致动所述第一控制表面,直到入射角达到该预定值,并且产生所述第二控制命令(36; 32,38,40,42)来添加的偏转 第二控制表面的当入射角为预定值以上。
