Abstract

A method for obtaining the profile-form which has the given surface pressure distribution is stated. The method is based on a theorem about the velocity along a profile and enables us to obtain separately the thickness distribution as well as the mean camber line of the required profile by simple calculations. Therefore, we can easily understand the relation between the pressure distribution and the profile form. Calculation has been made for a Joukowski profile which has the thickness of 11 percent and the camber of 2.5 percent of chord and Munk 6 profile. It showed that the deviation of the calculated form from the exact one was very small, which proves that the present method is very satisfactory for practical use in respect to the facility of calculation and to the accuracy of result.
