清潔的熱氣體輸送到機油冷卻器，氣體迅速從850 c冷卻至室溫，同時開始驅動氣體發動機並使其成為產生電能的發電機，增加鍋爐燃料以生成蒸汽用於進行更多的熱處理並生產更多的電能。The simulations results show that the average combustion temperature is much lower in fuel - rich state and little higher in oxygen - rich state near the best o / f ratio. by extending the post - chamber length the oxidizing gas and the fuel pyrolytic gas can burn completely and the average combustion temperature can be prominently increased. the fuel - rich recirculation zone close to the head of combustion chamber is very important for the combustion
計算結果分析表明：發動機在富燃狀態下平均燃燒溫度偏低，在接近理想配比的富氧狀態下平均燃燒溫度有所提高；加長補燃室可以大幅度提高發動機的平均燃燒溫度，並促進氧化劑氣體和熱解氣體的充分燃燒；燃燒室頭部的富燃迴流區對發動機的燃燒非常重要，去掉燃燒室頭部突擴段后，氧化劑氣體和燃料熱解氣體不能充分燃燒，發動機的平均燃燒溫度大幅下降。There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine, the components of incoming flow and its parameters, including total pressure, total temperature ( or total enthalpy ) and velocity must be simulated. at the same time, since the fuel ' s resident time within a combustor is very short, on the order of one millisecond, it is difficult to measure the flow - fields
進行雙模態沖壓發動機地面試驗研究時，必須要求試驗設備能模擬實際飛行條件下來流氣體的組分、總壓、總溫（或總焓）以及來流氣體的流動速度；同時由於燃料在燃燒室內駐留的時間很短，一般為毫秒量級，從而使流場物理量的測定顯得非常困難。With the oil resource shortage and the increasingly outstanding pollution of the environment in the world, it becomes an important project, studied by the international communities, to lower the fuel consume rate of the vehicle engine and the harmful compositions in the exhaust
