Abstract

When addressing the topic of this article, one is struck by a curious disparity between the needs of the designer of vehicles that move through the air or water and the subject matter that has proved most interesting to the theoretical aerodynamicist. Clearly the former is concerned with the flow over, and the pressures, forces, and moments experienced by, generally shaped streamlined bodies and multiple lifting surfaces (wings, tails, con­ trols) in intimate combination. Until recently he has had to place primary reliance for such information on measurements by wind tunnel and other experimental means. Except in particular cases, he has obtained only a rather piecemeal and preliminary sort of guidance from the products of rational theory, whose focus has been single, isolated, planar wings and slender bodies of revolution. Interference was the word chosen to describe situations where flow over one lif ting or body element was significantly affected by the presence of an­ other-as if, somehow, this interaction interfered with the purist's more appealing efforts to analyze each aerodynamic entity standing alone.
