主动操纵器对改善电传操纵旋翼机的操纵品质具有很大的潜力。在一项合作研究工作中，德国的DLR飞行系统研究所和美国陆军航空动力学局（AFDD）进行了几次飞行中试验，以研究循环操纵杆的动态特性（固有频率和阻尼）对旋翼机总体操纵品质的影响。进行实验，看看侧杆（DLR）和中心杆（AFDD）的速率和姿态命令响应类型的操纵器。本文介绍了两个不同的实验结果。第一个试验评估了前飞时的滚转操纵，并且只使用了侧杆操纵器。本实验中使用的任务是在帝国试飞员学校（ETPS）在DLR的飞行直升机模拟器EC 135 ACT/FHS上进行演习时设计的。ETPS还有助于优化用于测试的静态侧杆特性。第二个更全面的实验是评估ADS-33悬停和回转使命要素，实验中使用了侧杆和中心杆，可以直接比较两种类型的操纵器。对收集的飞行员等级进行回归分析，以系统地了解不同操纵者和响应类型的首选操纵杆特性。测试结果一致表明，首选的特征是最好的描述一阶响应模型。
Active inceptors offer great potential for improving the handling qualities of fly-by-wire rotorcraft. In a cooperative research effort, the DLR Institute of Flight Systems in Germany and the US Army Aeroflightdynamics Directorate (AFDD) conducted several in-flight experiments to study the influence of the dynamic characteristics (natural frequency and damping) of the cyclic stick on the overall handling qualities of a rotorcraft. Experiments were performed looking at sidestick (DLR) and centerstick (AFDD) inceptors for Rate and Attitude Command response types. The results of two different experiments are presented in this paper. The first experiment evaluated the roll handling in forward flight and was only performed with a sidestick inceptor. The task used in this experiment was designed during exercises of the Empire Test Pilots’ School (ETPS) on DLR’s Flying Helicopter Simulator EC135 ACT/FHS. ETPS also contributed to the optimization of the static sidestick characteristics that were used for the testing. The second, more comprehensive experiment, evaluating ADS-33 Hover and Slalom Mission Task Elements, was performed both with a sidestick and a centerstick allowing a direct comparison of both types of inceptors. Regression analyses were performed on the collected pilot ratings to gain a systematic insight into the preferred stick characteristics for the different inceptor and response types. The test results consistently suggest that the preferred characteristics are best described by a first-order response model.
