Dc torque motor under the reaction flywheel control mode was used in nacelle azimuth control in this paper 摘要实现了用直流力矩电机在反作用飞轮控制方式下对气球吊篮的方位控制。
The two astazou turboprops are mounted in slender nacelles in the leading edges of the wings and drive three - blade propellers 两台发动机安装在机翼上小巧的发动机舱内，各驱动一个三叶螺旋桨。
Each nacelle fully encloses the engines and fans ， greatly reducing the possibility of injury to soldiers who might be near the vehicle in the event of an engine fire or explosion 每个发动机舱都将发动机和风扇完全密封，这样，在发动机着火或爆炸事件中就可大大降低对航空器附近的士兵造成伤害的可能性。
Great power lift engineering and equipment company limited in jiangyan , taizhou city is a specialized manufacturer of nacelles , hoists , marine capstans and pile drivers in advanced level 泰州市姜堰巨能起重机械有限公司是一家专业生产具有国内先进水平的吊篮，卷扬机，船用起锚机和打桩机系列产品的企业。
The author founds the model for the blade , tower , nacelle and the hub of the 750kw wind turbine , and makes the basic ways of the loads calculation , then go on the static and dynamic simulating calculations 风力发电机组的建模仿真都是在bladedforwindows软件平台下完成的，文章对风力发电机组的叶片、塔架、机舱、轮毂进行了建模，确定了载荷计算的基本方法，进行了静态、动态模拟计算。
A mathematical model reflecting the tilt rotor unsteady and nonlinear aerodynamic characteristics in the longitudinal channel is presented in the paper . in the full flight envelope , the rotor thrust continues tilting and the aerodynamic forces of each component change as a function of airspeed and nacelle angle 在整个飞行包线内,旋翼的推力矢量方向不断变化,飞机各部件的气动力随发动机短舱倾角和空速的变化而变化,因而飞机的飞行动力学有很强的非定常、非线性特性。
