Available in PDF, EPUB and Kindle. Book excerpt: The favorable aerodynamic characteristics of the jet flap are appreciably affected by the presence of a ground plane. A theory for the two dimensional jet-flapped airfoil in ground effect is presented in the paper. The basic flow equations are derived and it is shown that while the field equation is linear, the boundary conditions are not. By a conformal mapping, the original problem is con verted to one of an extremely simple geometry, and applying the appropriate kinematic and dynamic boundary conditions, the basic equation is derived. The singularities of the equation are identified and discussed; in the transform plane they consist of logarithmic terms at the trailing edge and simple polar terms, O(1/x), at the leading edge. In the case of no ground plane, the integro-differential equation derived by Spence follows directly from the equation developed here. The singularities are 'removed' by the addition of functions exactly satisfying the integrodifferential equation at the singular points. The remaining terms can be approximated and evaluated by a collocation process involving two Fourier Series. A matrix, whose inverse defines these Series, is developed, its elements being generated in a form suitable to digital computer techniques. (Author).

This book was released on 2013-03-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the memory of a distinguished Russian engineer, Rostislav E. Alexeyev, who was the first in the world to develop the largest ground effect machine - Ekranoplan. One of Alexeyev's design concepts with the aerodynamic configuration of a jlying wing can be seen on the front page. The book presents a description of a mathematical model of flow past a lifting system, performing steady and unsteady motions in close proximity to the underlying solid surface (ground). This case is interesting for practical purposes because both the aerodynamic and the economic efficiency of the system near the ground are most pronounced. Use of the method of matched asymptotic expansions enables closed form solutions for the aerodynamic characteristics of the wings-in-ground effect. These can be used for design, identification, and processing of experimental data in the course of developing ground effect vehicles. The term extreme ground effect, widely used through out the book, is associated with very small relative ground clearances of the order of 10% or less. The theory of a lifting surface, moving in immediate proximity to the ground, represents one of the few limiting cases that can be treated analytically. The author would like to acknowledge that this work has been influenced by the ideas of Professor Sheila E. Widnall, who was the first to apply the matched asymptotics techniques to treat lifting flows with the ground effect. Saint Petersburg, Russia February 2000 Kirill V. Rozhdestvensky Contents 1.
