The Linear Theory of a Lifting System Moving Close to the Ground,To reduce a nonlinear formulation to the linear theory, one has to assume that the deflections of the surfaces of the wing, its vortex wake, and the ground, respectively, from horizontal planes . = .. and . = 0 are small compared to the ground clearance ., i.e.,

The Aerodynamic Efficiency of a Wing in the Extreme Ground Effect,The theory of a wing in the extreme ground effect, as developed herein, enables us to formulate a number of extremal problems, which are of both theoretical and practical interest.

https://doi.org/10.1007/978-3-8349-9933-7teady subsonic flow is one of the most challenging in lifting surface theory; see Belotserkovsky et al. . The complexity of the problem partly stems from the fact that in a compressible fluid the perturbations propagate with finite speeds.

Book 2000 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 t
