5.38 Consider a single-engine jet (turbofan) aircraft with the following features: mro 7400 kg, S = 110 m, e = 0.92, AR = 9.2, CD = 0.024 Maximum speed at 12,000 ft is 270 KTAS. You are required to add another engine to this aircraft with the same thrust (to have a twin engine). Determine the maximum speed for the twin-engine configuration at 25,000 ft in KEAS.
