Ground effect of helicopter is described in terms of performance effects and hovering flow mechanics; data indicate that helicopter in ground effect requires only minor increase in power during transition to forward flight, and only small losses of ground effect occur when hovering over sloped surface; comparison of lifting efficiencies of helicopter and peripheral jet ground effect machines shows that latter can not compete with helicopter for many missions.
