The theoretical and experimental investigations on ground erosion, carried out in connection with the development of the V/STOL transport aircraft Do 31, are summarized. A mobile test rig with a one stream Orenda 14 jet engine was developed for the experiments. The resistance, which is dependent on jet intensity, was tested of wet and dry grassland at Memmingen and Oberpfaffenhofen, conventional concrete, special concrete, asphalt, synthetic coating, and ground reinforced by water-glass. The movement of particles in the wall jet was also investigated. Reduction of the lift jet intensity and special methods of STOL to avoid ground erosion are considered. (Author)
