小型渦輪發動機除了可應用在無人駕駛飛機(UAV)的推進，亦可作為發電的用途，有可觀的發展空間。唯目前除了麻省理工學院以MEMS的技術製作的微型發動機外，一磅以下推力等級的微型渦輪發動機仍缺乏研究與實體產品。本研究嘗試以小型渦輪發動機的設計方法與理論基礎以及傳統的精密加工方式製作一個約拇指般大小的微型渦輪發動機。此微型渦輪發動機總尺寸為4.76cm長，2.40cm直徑，轉速300000rpm，設計推力等級為100公克。一個以量測其基本特性參數的小型測試台在本研究中也建立起來，未來希望藉由量測的結果探討設計的準確度，作為未來發展與研究的參考。

The micro gas turbine engine has a good potential for UAV propulsion and power generation applications. Whereas the turbine engine with thrust level below 1 lbf is non-exist, except the MIT micro turbine made by MEMS technology. The objective of the present study is trying to design a 100g thrust level micro turbine engine. The approach of the design is similar to that used in 10 lbf thrust level micro turbine engines. The basic requirement is that the engine components can be made by traditional precision machining methods. The designed micro turbine engine has a overall dimension of 4.76 cm in length, and 2.40 cm in diameter. The thrust is 100 g at 300000 rpm. A test bed to measure basic performance parameters is built to verify the design for future design improvement.
