Source sentences:
text: It is evident, therefore, that the airplane designer is interested in obtaining an airfoil that will produce high lift and low drag over the airplane's flying range of "angles of attack," (the angle of attack being the acute angle between the chord of an airfoil and the direction of the relative wind).
text: High Lift, High Drag
text: A drawback of the numerical trial and error optimization process is that it can take a long time, and that the optimization programs tend to move into a corner of the requirements: the resulting airfoil might indeed have a low drag and high lift, but maybe only in a very small operating range
