| titleOfInvention | The choosing method of rail control engine combustion chamber, a kind of space best features length |
| abstract | The present invention relates to the choosing method of rail control engine combustion chamber, a kind of space best features length, it is characterized in that, comprise the following steps: 1) determine motor chamber diameter, chamber length and combustion chamber throat diameter, thereby determine engine chamber characteristic length L; 2) measure chamber pressure P c With propellant flow rate q m , calculate combustion chamber actual characteristic speed c * ; 3) the efficiency of combustion η of calculation engine combustion chamber c ; 4) by engine chamber in the brachymemma of straight tube place, repeating step 1)-3), obtain 9 groups of efficiency of combustion η c With its characteristic of correspondence length L; 5) solve One-place 2-th Order multinomial η c ＝aL 2 Coefficient a, the b of+bL+c, the numerical value of c; 6) draw this relation equation matched curve, the characteristic length value at this matched curve summit place is best features length. Adopt method of the present invention to realize and choose best features length to reach maximum efficiency of combustion, reduce the object of test period and funds, there is very large defense economy benefit. |
