A method is developed for calculating the flow and the lift force on a slender pointed wing in a parallel stream whose velocity varies in the vertical direction. The Euler equations of flow are linearized for small disturbances to the nonuniform stream, and an integral equation for lift distribution on the wing is deduced, using the simplifying assumption of small aspect ratio. The integral equation is solved by an analytic expansion. Solutions calculated for several stream velocity profiles show how the lift varies with the velocity ratio of the stream and with the ratio of the wing span to the vertical extent of the nonuniform region.
