Nonlinear Flow Problems for a Lifting System in the Extreme Ground Effect

  • Kirill V. Rozhdestvensky

Abstract

First, we consider an example of a flow problem for a moderately curved thin foil in the ground effect,1 and then present some results for thick foils. Essentially, as discussed at length in section 2, the procedure for the solution uses the assumption that, for h ≪ 1 and ε = O(h), nonlinear effects exhibit themselves mainly in the narrow channel under the foil. The foil and the corresponding coordinate system are shown in Fig. 4.1.
