摘要: 
雖然往復式汽油引擎為現代車用引擎的主流,然而渦輪軸引擎為一
純旋轉引擎,亦有不可忽視的優點,例如高功率重量比、高馬力燃料
比、低污染、機件簡單、多重燃料等優點。目前渦輪軸引擎在多數運轉
狀況下,採用效率較高的軸流式渦輪,而燃燒室高溫的燃燒氣體進入
渦輪段時,對高速運轉中的渦輪葉片形成嚴酷的物理環境,造成高溫、
高應力、振動、潛變等許多的問題。若能解決上述問題,將使渦輪油引
擎在激烈競爭的車用引擎市場中佔有一席之地
本文首先針對簡單俐落的脈衝式噴射引擎進行理論與實驗探討,
期能將渦輪軸引擎之渦輪葉片的傳統缺失作釜底抽薪之改進,乃利用
脈衝式噴射引擎作為氣體產生器,配合旋噴機構,搭配設計成新穎無
渦輪葉片之旋噴式脈衝噴射引擎,再進行理論分析與性能實驗,已獲
相當成果,並奠定了未來研發車用無渦輪葉片之旋噴式噴射引擎的重
要基礎。

Although the reciprocating gasoline engines currently are the major power plants for land vehicles, significant merits with regard to purely rotating turboshaft engine shall not be neglected either; for examples, high power/weight ratio, high power/fuel ratio, low pollution, relatively simple engine construction, and etc. The turboshaft engines enjoy higher efficiency by employing axial gas turbine in most operation cases, the high-temperature gases of combustor enter the turbine section and form a strict physical environment for gas turbine blades in high-speed rotating. Thus, they induce many problems such as high temperature, high stress, vibration, creep, and etc. If the associated mechanical problems can be solved, the turboshaft engine will stand a more important place in the keen competition market of vehicle engines. Herein, first the theoretical analysis and performance tests are conducted for the simple pulsejet engine. In order to revolutionally improve the traditional deficiencies of turboshaft engines, a novel turbine-blade-less pulsejet sprinkler engine is designed by assemblying the pulsejet engine as gas generator with a special sprinkler mechanism, then the theoretical analysis aspect and experiments of this innovative enginer are performed. In this study, a sound research basis is achieved for later development of bladeless jet-sprinkler engines.
