The conclusion that the optimal secondary nozzle exit area generating the maximum thrust agrees well with the numerical simulation , indicating that the exit area of secondary nozzle should be optimized according to structure and flow parameters during design 表明在引射火箭設(shè)計時,應(yīng)結(jié)合引射火箭的結(jié)構(gòu)和流動參數(shù)對二次噴管出口面積進行優(yōu)化設(shè)計,以達到最佳推力性能。
The results indicate that with decrease of exit area of secondary nozzle , the bypass ratio is decreasing , and the static pressure in integrated ejector combustor is increasing , and mixing condition becomes better . there exists an optimal exit area of secondary nozzle to get maximum thrust of rocket ejector 結(jié)果表明:引射能力隨著二次噴管出口面積的減小而減?。徽w式引射燃燒室壓強隨著二次噴管出口面積的減小而上升,混合隨之更為充分;存在一個最優(yōu)的二次噴管出口面積,使發(fā)動機推力最大。
It is shown that when the exit area of secondary nozzle and the fuel / oxidizer ratio is fixed , the increase of mass flow rate of secondary flow lead to the decrease of velocity of mixed flow , and increase of total mass flow rate . the synthetical result of these two phenomenon cause the increase of thrust of rocket ejector , but the increasing magnitude is relatively small , indicating that these is no necessary to claim large bypass ratio in rocket ejector design . in the comparison between two configurations , the typical one has better performance , indicating the importance of pressure ratio 結(jié)果表明:在固定二次噴管出口面積和氧燃比的條件下,二次流(引射空氣流)流量的增加引起混合氣體出口速度的下降和總流量的增加,二者綜合作用使發(fā)動機推力增加,但增幅不大,表明在設(shè)計發(fā)動機結(jié)構(gòu)和工作參數(shù)時,不必過分追求大的引射系數(shù);兩種結(jié)構(gòu)的性能對比分析表明了增壓比對引射火箭性能的提高具有重要意義;對引射火箭的熱力循環(huán)分析同樣表明,增壓比對于提高發(fā)動機性能非常關(guān)鍵。
