Description: In an earlier work Krynytzky (1971) investigated the performance of a helicopter landing in the steady-state mean flow-field behind a tall building in a wind tunnel. The present paper extends his method to the case of an unsteady flow field. A model is first developed for the gusty wind over a block two-dimensional geometry building. A set of simplified dynamic equations governing the motion of a helicopter is then derived. Finally the performance of the helicopter in an unsteady wind field about the building is computed for the helicopter landing or taking off on a 6 deg glide slope over the building.
