A numerical technique based on known methods was developed to predict the takeoff and landing performance characteristics of powered lift aircraft. Two-degree-of-freedom equations of motion treating the aircraft as a point mass are integrated using numerical techniques based on Euler's method of forward integration. The analysis includes the calculation of all engines operating takeoff distance, critical field length, landing distance and climb capability. Predictions were made for aircraft with externally blown flaps and upper surface blown flaps and compared with the performance quoted by the respective airframe manufacturer. Good correlation was achieved. (Author)
