By Kirill V. Rozhdestvensky

This ebook is devoted to the reminiscence of a special Russian engineer, Rostislav E. Alexeyev, who used to be the 1st on the planet to enhance the most important flooring influence computing device - Ekranoplan. considered one of Alexeyev's layout thoughts with the aerodynamic configuration of a jlying wing may be noticeable at the entrance web page. The ebook offers an outline of a mathematical version of move prior a lifting process, acting regular and unsteady motions in shut proximity to the underlying strong floor (ground). this situation is fascinating for functional reasons simply because either the aerodynamic and the commercial potency of the method close to the floor are so much reported. Use of the strategy of matched asymptotic expansions allows closed shape recommendations for the aerodynamic features of the wings-in-ground impact. those can be utilized for layout, identity, and processing of experimental facts during constructing floor impact cars. The time period severe flooring impression, wide-spread via­ out the publication, is linked to very small relative flooring clearances of the order of 10% or much less. the idea of a lifting floor, relocating in speedy proximity to the floor, represents one of many few restricting instances that may be handled analytically. the writer want to recognize that this paintings has been inspired through the guidelines of Professor Sheila E. Widnall, who was once the 1st to use the matched asymptotics thoughts to regard lifting flows with the floor impression. Saint Petersburg, Russia February 2000 Kirill V.
