In this paper, the impacts of the uncertainty of fuel heating value as well as the burner efficiency onperformance functions of a turbofan engine are studied. The mean value and variance curves for thrust,thrust specific fuel consumption as well as propulsive, thermal and overall efficiencies are drawn andanalyzed, considering the aforementioned uncertainties based on various Mach numbers at a number offlying altitudes in order to yield a more accurate prediction of values of performance functions. Theresults of this study can be of essential significance for an optimal and robust design of turbofanengines. This study is done employing Monte Carlo Simulation method which is a probabilisticanalysis method.
