Nonlinear Flow Problems for a Lifting System in the Extreme Ground Effect,. Essentially, as discussed at length in section 2, the procedure for the solution uses the assumption that, for . ≪ 1 and ε = O(.), 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.

The Influence of Endplates, Flaps, and Slots,e wing’s tips and are intended to decrease leakage of air from under the lifting system. Consequenly, the mounting of endplates results in the augmentation of lift or in a decrease of the induced drag for a given lift. In practice, the configuration of the endplates can vary. Figure 6.1 illustrates

The Aerodynamics of a Lifting System Near Curved Ground,rough seas. The approach of matched asymptotic expansions furnishes a simplified mathematical model of the unsteady aerodynamics of the wing-in-groundeffect vehicle, based on the idea of domination of the channel flow in the extreme ground effect. This concept seems to be promising for wave perturba

Schematized Flow Models for a Power-Augmented Lifting System, the craft from water. An efficient way to facilitate takeoff consists of blowing air under the main wing of the craft from special engines. This mode of vehicle operation is often called . or, briefly, .. Power augmentation provides additional dynamic head to support the vehicle at small speed and

Integral Formulations for Lifting Surfaces in the Extreme Ground Effect,sentially, in the extreme ground effect, we study the limiting process, when the distance between two double (vortex) layers, representing the wing and its mirror image, becomes vanishingly small. In the limit, the two double layers merge into a . so that the procedure can be characterised as ... Th
