然而安装一个齿轮减速器后，涡轮可以高速驱动低速运转的风扇。
A gearbox, however, allows the turbine to operate at a high speed while driving the fan at a lower speed.
这种发动机在风扇与涡轮间安装了一个齿轮减速器。
Unlike a conventional turbofan, it USES a gearbox rather than a shaft between the fan and the turbine.
应用：合适1：18房车动力。函道风扇以及带减速齿轮的高效率动力系统。
Applications:Good for 1:18 on road car, ducted fan power and with gearbox for high efficiency power system.
