A pulse response test of an aircraft turbofan engine has been conducted in ground-level static conditions in order to obtain dynamical characteristics of the engine in the linear operating range and to develop a high-fidelity mathematical simulation model. The engine test results have been compared with the simulation results in regard to frequency characteristics of rotor speed for fuel flow perturbations. By taking the heat capacity of the combustion chamber into account, we have improved the phase lag characteristics of the model. Examination of other characteristics such as time constants of high-pressure rotor speed at various operating points has verified the high fidelity of the modified simulation model.
