  2. The calculation results indicate that the starting performance of forebody / inlet with wedge - shaped lip is better than that with plane lip at low flight mach number. at high flight mach number, the performance of the forebody / inlets designed by the two methods is approximate. at low flight mach number, the starting performance of forebody / inlet designed by the method of constant shock wave intensity is better

    結果表明:唇口帶楔角的進氣道在低飛行馬赫數下的起動性能優于唇口平直的進氣道;採用等激波強度和等激波角度方法設計的進氣道在高飛行馬赫數下的性能相近,在低飛行馬赫數下,採用等激波強度方法設計的進氣道起動性能較優。
  3. The effects of such elements as primary flow total pressure, flow rate, degree of fuel rich, nozzle structure, flying speed and secondary combustion on ejecting mode performance were researched. it was found that thrust augmentation can be achieved on the condition that the flying mach number is above 0. 7. to deeply analyze thrust augmentation mechanism in low speed range, the research was further continued by changing secondary combustion organization and aft - body configuration

    研究了一次流總壓、流量、富燃程度、噴管結構、二次流來流速度、二次燃燒組織對引射模態性能的影響,發現實驗樣機構型在0 . 7ma以上的飛行條件下可以獲得推力增強,而在0 . 7ma以下無推力增強。
