• Linear theory was constructed on a thin, jet-flapped airfoil with fully developed wake which was operated between free surfaces of a free jet stream. This theory was based upon the Tulin's linear theory and the thin jet theory of D. A. Spence (Ref. 1). The basic relation was expressed as a integro-differential equation for the slope of the jet. The solution was expressed as the sum of a Fourier series together with the function possessing the form of logarithmic behavior. Important results are : (1) when the airfoil exists in the jet stream, the lift coefficient decreases as te width of the jet stream becomes narrow ; (2) when an airfoil exists beneath the free surface, the lift coefficient increases as the distance from the free surface becomes small.
