...19. In a flat plane, the pressure is always perpendicular to the surface and, as already pointed out, the ratio of lift to drift is, therefore, as the cosine to the sine of the angle of incidence. The angle of incidence is the angle at which the plane is inclined to the air current. But in curved... | |
