简介:


内容为：
涡轮原理，涡轮喷气航模设计,fd3-64涡轮喷气发动机设计，自制涡轮喷气发动机fd3-64安装与制作过程，及详细尺寸图）


修订后，扩大和更新的第三版，这本书受欢迎的。在某程度上，它占据了从schreckling的书籍，但是坎普的看法，设计与科技，是更广泛的，用照片和截面的发动机，以显示不同的方法去做事情。这不是贬低schreckling的书籍，这只是其中一个考虑，他们就到下一阶段。包括基本计划和指令，为建设一个小（ 110毫米直径）发动机。 109个很好的说明页面。



fd3-64


《航空涡轮风扇发动机》 为专业发动机教材，供研究航模涡轮发动机有需要的朋友做参考使用。


新增《DIY a Gas-Turbine Engine from an Autornobile Turbocharger Rules

of Thumb》 《用增压器设计涡喷Design and Perfornlance of a Gas-Turbine Engine from

an Autornobile Turbocharger》供制作增压器涡喷作参考。


实际操作请注意安全，涡轮危险，慎防高速飞溅物！
