Estimate the maximum airspeed for the jet aircraft if it is flying a constant altitude of 4.5 km. mass, m = 12000 kg wing reference area, S = 29 m2 CD = CD0 + K*CL*CL CD0 = 0.04 + 0.02*tanh[5.0*(M-0.95)] K = 0.7 + 0.2*tanh(5.0*(M-0.95)] Engine: (M = Mach number, h = altitude [km], T = max thrust [kN]) T = 78.7 + 13.3*M - 6.3*h + 0.13*h*h + 7.3*M*M - h*M Standard Atmosphere at 4.5 km: density, rho = 0.78 kg/m3 speed of sound: sos = 322 m/s, M = V/sos maximum airspeed = _________________ [m/s]
