Based on the above-idle component-level model,a two-spool turbofan engine startup model was developed using extrapolated component characteristics.The model can simulate the whole startup process on ground from near static conditions to idle.The influence of the fuel-air ratio on combustion efficiency was taking into account.Heat transfer model was also established to estimate the influence of heat transfer on combustor,high pressure turbine and low pressure turbine.The total pressure loss coefficients of different components varied with the high rotor speed.The method of volume dynamics was used in order to avoid the iterative calculations.Results show that the accuracy of the real-time model is good,and the dynamic simulation error is less than 5%.The model meets the requirements of semi-physical simulation.
