If the airplane is operated in steadyįlight at (L/D)max the total drag is at a minimum. Note that the maximum lift-drag ratio, (L/D) occursĪt one specific angle of attack and lift coefficient. ![]() Of attack shows that L/D increases to some maximum then decreases at the higher liftĬoefficients and angles of attack. The resulting plot of lift-drag ratio with angle With the lift and drag data available for the airplane, the proportions of CL and CD canīe calculated for each specific angle of attack. Aerodynamics for Naval Aviators (1965) has answers for tough questions:Ī factor more important in airplane performance considerations is the lift-drag ratio, L/D. ![]() So, what is the max bank angle for a car to hold a steady rate turn while maintaining altitude? See. For example, a car has 圆 the drag coefficient of a wing. DSD, ignore comparisons between cars and aircraft.
