Abstract: Immunity Strategy algorithm was developed to study the static characteristics of the full-flow staged combustion cycle liquid propellant rocket engine. The immune strategy algorithms were proposed based on the theory of immunity in biology. Immunity strategy algorithm of solving the large dimension non-linear mathematical model was presented. It converts the problem of solving non-linear equations into the optimization problem of the solving the minimum value with constraints. The cross operator, mutation operator and the process of immune operation were presented. Calculation results show that using Immunity Strategy algorithm can show the static characteristics of the full-flow staged combustion cycle liquid propellant rocket engine, and evidently restrain the degeneration phenomenon during the evolutionary process, and thus increase the convergent speed greatly.
