Dc torque motor under the reaction flywheel control mode was used in nacelle azimuth control in this paper 摘要實(shí)現(xiàn)了用直流力矩電機(jī)在反作用飛輪控制方式下對(duì)氣球吊籃的方位控制。
The two astazou turboprops are mounted in slender nacelles in the leading edges of the wings and drive three - blade propellers 兩臺(tái)發(fā)動(dòng)機(jī)安裝在機(jī)翼上小巧的發(fā)動(dòng)機(jī)艙內(nèi),各驅(qū)動(dòng)一個(gè)三葉螺旋槳。
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 每個(gè)發(fā)動(dòng)機(jī)艙都將發(fā)動(dòng)機(jī)和風(fēng)扇完全密封,這樣,在發(fā)動(dòng)機(jī)著火或爆炸事件中就可大大降低對(duì)航空器附近的士兵造成傷害的可能性。
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機(jī)械有限公司是一家專業(yè)生產(chǎn)具有國(guó)內(nèi)先進(jìn)水平的吊籃,卷?yè)P(yáng)機(jī),船用起錨機(jī)和打樁機(jī)系列產(chǎn)品的企業(yè)。
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 風(fēng)力發(fā)電機(jī)組的建模仿真都是在bladedforwindows軟件平臺(tái)下完成的,文章對(duì)風(fēng)力發(fā)電機(jī)組的葉片、塔架、機(jī)艙、輪轂進(jìn)行了建模,確定了載荷計(jì)算的基本方法,進(jìn)行了靜態(tài)、動(dòng)態(tài)模擬計(jì)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 在整個(gè)飛行包線內(nèi),旋翼的推力矢量方向不斷變化,飛機(jī)各部件的氣動(dòng)力隨發(fā)動(dòng)機(jī)短艙傾角和空速的變化而變化,因而飛機(jī)的飛行動(dòng)力學(xué)有很強(qiáng)的非定常、非線性特性。
The nacelle ( ) is a cover housing (separate from the fuselage) that holds engines, fuel, or equipment on an aircraft. In some cases?for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning?an aircraft's cockpit may also be housed in a nacelle, which essentially fills the function of a conventional fuselage.
