To predict exhausted jet flow and contrail in specific altitude from rocket engine efficiently, an engineering method was performed to calculate jet flow including afterburning and contrail effect. Control equations based on one-dimensional flow theory, turbulent mixing and equipment chemistry reaction were solved by the method of fourth-orders Runge-Kutta. Model verification and example prove that typical parameters of exhausted jet flow in the jet flow region could be achieved by this method, which is more computationally efficient.
Key words： exhausted jet flow; contrail; afterburning; engineering calculation method
