無人飛行載具除休閒娛樂外，其在許多領域上皆有大規模應用案例，然對於以電池為主要動力的大多數機種而言，電池的性能成為一重大瓶頸。目前市面上多旋翼無人載具滯空時間約25 min左右，大型植保機則多落於10～15 min上下，如何提升續航力成為該領域長期探討的議題。吾人認為結合石化燃料的混合動力系統有利於無人載具在如起飛重量及滯空時間等特定指標的性能提升，以擴展應用領域及增加使用效益。
本研究為微渦輪發電系統發展計畫載具動力分支的先導技術評估，目標為設計製造一適配於無人載具之微渦輪發電系統。吾人將使用KingTech的K60-TP渦輪軸發動機作為動力核心並選配合適的發電機以開發相關配套技術。現階段以地面機台測試為主，旨在了解發動機運轉特性與發電輸出表現，判斷發電系統是否符合性能需求？
分析實驗數據可知，當永磁無刷馬達做為發電機運用時，其馬達速度常數K_V會隨著發電功率上升而增加，於本研究最高功率輸出時約為標稱值1.4倍。實驗結果顯示於核心渦輪轉速160,000 rpm下，系統可輸出42.4 V、110 A，功率最高達4.6 kW，符合設定案例的起飛懸停功率需求，系統比滯空為153.51 s/kg，熱效率2.6 %，滯空時間從鋰電池10 min增加至發電系統22 min，大幅增加1倍以上。續航力分析方面，以5 kg燃油酬載計算每提升1 %熱效率則可增加約43 %續航時間。至此吾人可宣稱微渦輪發電系統用無人載具能源提供於理論及工程上皆為一可行方案。

In addition to leisure and entertainment, unmanned aerial vehicles have widely applications in many fields. However, for most models that use batteries as their main power, battery performance becomes a major bottleneck. For the consumer drone on the market, the endurance is about 25 minutes, while that of the agricultural spraying drone usually falls within 10-15 minutes. How to improve the endurance has become a long-term topic in this field. It is believed that the hybrid power system is conducive to the performance improvement of unmanned vehicles, so as to expand the application field and increase the utilizations efficiency.
The goal of this research is to design and manufacture a micro-turbine power generation system suitable for unmanned vehicles. K60-TP turboshaft engine is used as main power source, and appropriate generators is selected to develop related supporting technologies. The ground-based testing is mainly used to understand engine operating characteristics and power generation performance, and to determine whether the system meets performance requirements.
According to the experimental results, the system can generate 42.4 V, 110 A at the core turbine speed of 160,000 rpm, power output is up to 4.6 kW. The system's specific endurance is 153.51 s/kg, thermal efficiency is 2.6189 %, and the endurance is increased from 10min for lipo batteries to 22 min for the power generation system, which is more than doubled. In the end, it is concluded that the micro turbine generator system apply to unmanned vehicles power supply is a feasible solution in both theory and engineering.
