Abstract: The model of combustion efficiency for scramjet combustor is analyzed and presented in this paper.The model involves effect factors of fuel injection, entrance conditions and combustor configuration.Using the model of combustion efficiency the resulting (one-dimensional) flow properties is computed step by step through the combustor.The comparisor of the experimental results and theoretical predictions indicates that the theory is adequate.
