Keywords: Drag curves for aircraft in flight.svg parasitic drag increases with the square of flight velocity; The lift-induced drag decreases with the square of velocity As a result the total drag the sum of both components typically has a minimum value In practice the validity of these curves is limited by the occurrence of stall on the left side and by compressibility effects on the right side 2016-10-01 own Olivier Cleynen other versions cc-zero Drag fluid dynamics Aircraft flight mechanics Aerodynamics diagrams |
