This publication is devoted to the reminiscence of a special Russian engineer, Rostislav E. Alexeyev, who used to be the 1st on this planet to enhance the most important flooring impact computer - Ekranoplan. considered one of Alexeyev's layout thoughts with the aerodynamic configuration of a jlying wing should be obvious at the entrance web page. The publication offers an outline of a mathematical version of circulate prior a lifting approach, acting regular and unsteady motions in shut proximity to the underlying reliable floor (ground). this example is fascinating for useful reasons simply because either the aerodynamic and the commercial potency of the method close to the floor are such a lot reported. Use of the strategy of matched asymptotic expansions permits closed shape strategies for the aerodynamic features of the wings-in-ground impression. those can be utilized for layout, id, and processing of experimental facts during constructing floor influence automobiles. The time period severe flooring impression, universal via­ out the publication, is linked to very small relative floor clearances of the order of 10% or much less. the idea of a lifting floor, relocating in quick proximity to the floor, represents one of many few proscribing circumstances that may be taken care of analytically. the writer want to recognize that this paintings has been prompted through the tips of Professor Sheila E. Widnall, who used to be the 1st to use the matched asymptotics options to regard lifting flows with the floor impact. Saint Petersburg, Russia February 2000 Kirill V.
