This publication is devoted to the reminiscence of a unusual Russian engineer, Rostislav E. Alexeyev, who used to be the 1st on the planet to boost the biggest flooring impression computer - Ekranoplan. one in every of Alexeyev's layout recommendations with the aerodynamic configuration of a jlying wing may be obvious at the entrance web page. The e-book provides an outline of a mathematical version of stream earlier a lifting method, appearing regular and unsteady motions in shut proximity to the underlying reliable floor (ground). this situation is fascinating for sensible reasons simply because either the aerodynamic and the commercial potency of the approach close to the floor are so much said. Use of the tactic of matched asymptotic expansions permits closed shape suggestions 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 floor impression, standard via­ out the ebook, 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 restricting instances that may be taken care of analytically. the writer wish to recognize that this paintings has been prompted by means of the information of Professor Sheila E. Widnall, who used to be the 1st to use the matched asymptotics recommendations to regard lifting flows with the floor impact. Saint Petersburg, Russia February 2000 Kirill V.
