  1. The effect of area ratio, mach number, total pressure of primary rocket and geometry structure of primary rocket on ejectorjet performance was studied

    通過數值計算研究了引射火箭堵塞比、來流馬赫數、一次火箭燃燒室總壓、一次火箭構型對引射火箭性能的影響。
  2. The main results are : supersonic region and subsonic region can co - exist in flow path simultaneously, subsonic flow is insignificance for engine performance ; total pressure of primary rocket should be decreased when mach number is increased. in the experimental aspect, some components of ejectorjet experimental system were improved, ejectorjet experiments using alcohol as secondary fuel were conducted

    由數值計算獲得的結論為:引射火箭內的一般流態為超音速區與亞音速區共存,亞音速區不具備做功能力;飛行馬赫數增大,引射火箭內更易於產生壅塞;為了獲得最佳的性能,隨著飛行馬赫數的提高,應當降低一次火箭的工作壓強。
