Abstract : The structure of the singularity in the pressure distribution at parabolic wing tips is investigated on the circular wing model; it is determined on the basis of the remark that the given downwash is always regular at the tip. The solution is characterized by the occurrence of logarithmic sets. The major part of the solving set describes the singularity which is common to all solutions; the minor part which describes the special solution can be separated out. The leading components of the singularity can be generalized to apply to more general wing planforms. (Author)
