This booklet is devoted to the reminiscence of a unusual Russian engineer, Rostislav E. Alexeyev, who was once the 1st on the earth to enhance the most important floor impact laptop - Ekranoplan. certainly one of Alexeyev's layout options with the aerodynamic configuration of a jlying wing should be obvious at the entrance web page. The ebook offers an outline of a mathematical version of movement prior a lifting procedure, acting regular and unsteady motions in shut proximity to the underlying stable floor (ground). this situation is attention-grabbing for functional reasons simply because either the aerodynamic and the commercial potency of the approach close to the floor are so much reported. Use of the strategy of matched asymptotic expansions allows closed shape options for the aerodynamic features of the wings-in-ground influence. those can be utilized for layout, identity, and processing of experimental info during constructing flooring influence autos. The time period severe floor influence, known via­ out the ebook, is linked to very small relative floor clearances of the order of 10% or much less. the speculation of a lifting floor, relocating in speedy proximity to the floor, represents one of many few proscribing circumstances that may be taken care of analytically. the writer wish to recognize that this paintings has been motivated through the information of Professor Sheila E. Widnall, who was once the 1st to use the matched asymptotics recommendations to regard lifting flows with the floor impact. Saint Petersburg, Russia February 2000 Kirill V.
