The Boeing 727 airplane has a gross weight of 125000 lbf, a wing area of 1200 ft2, and an aspect ratio of 6. It has two turbofan engines and cruises at 532 mi/h at 30000 feet standard altitude. Assume that the airfoil is the NACA 2412 section from Prob. 8.83. If we neglect all drag except the wing, what thrust is required from each engine for these conditions?
