Remarks About Aerodynamic Coefficients• An increase in flap angle increases both C L and C D .However, these increments are not linear andconsequently are more difficult to interpret• Increasing the flap angle * f increases and thusreduces the lift-<strong>of</strong>f speed required for take<strong>of</strong>f due to anincrease in the lifting force generated.( ) C LC D• Increments in flap angle increases the value <strong>of</strong> morerapidly which tends to reduce more drastically theacceleration <strong>of</strong> the aircraft on the runway thus increasingthe runway length necessary to reach the lift <strong>of</strong>f speedVirginia Tech - <strong>Air</strong> <strong>Transportation</strong> <strong>Systems</strong> Laboratory 35
