ducted-fan

基本解釋

A jet engine that provides extra thrust by means of a ducted fan in its forward end that draws in extra air.
渦輪風(fēng)扇發(fā)動(dòng)機(jī)一種噴氣發(fā)動(dòng)機(jī)，前有一管道風(fēng)扇吸入額外量的空氣，這部分空氣經(jīng)壓縮后提供額外推力
Applications:Good for 1:18 on road car,ducted fan power and with gearbox for high efficiency power system.
應(yīng)用：合適1：18房車(chē)動(dòng)力。函道風(fēng)扇以及帶減速齒輪的高效率動(dòng)力系統(tǒng)。
The train is propelled by ducted fans.
這種火車(chē)用渦扇推進(jìn)器。
Compared with the propeller or the rotor, the ducted fan provides a larger aerodynamic thrust (lift) and the low noise due to the shrouding duct.
摘要涵道風(fēng)扇較同樣直徑的孤立風(fēng)扇能產(chǎn)生更大的升力，且風(fēng)扇環(huán)括在涵道內(nèi)，既可阻擋風(fēng)扇氣動(dòng)聲向外傳播，又結(jié)構(gòu)緊湊、安全性高。
