81/2 x 11 128 pgs 150 color & b&w photos For decades the Soviet Union and now Russia have held leading positions in the development of a special class of vehicles that are neither aircraft nor ships or both at once. Known as wing-in-ground effect (WIGE) craft or by their Russian name of ekranoplan, these vehicles combined the best of both worlds, operating on the borderline between the sky and the sea, offering the speed of an aircraft coupled with better operating economics and the ability to operate pretty much anywhere on the world's waterways. As such they promptly attracted the attention of the military and thus have been veiled in secrecy until recently.The book describes in detail the many series of WIGE vehicles developed by various design bureaus, including the Orlyonok, the only ekranoplan to see squadron service, the missile-armed Loon and the famous and awesome KM, or Caspian Sea Monster, which first attracted the attention of the West to these developments.

One of the most unusual strands in aviation history has been the development of wing-in-ground effect (WIG) vehicles, or as they are more commonly known by their Russian name, Ekranploans. Beginning with a brief outline of the concept from the theory to viable technical solutions, this new, expanded edition of Soviet and Russian Ekranploans gives a historical survey of the development of WIG research and construction in Russia. A large part of the book focuses on a type-by-type description of specific designs of ekranoplans developed in the Soviet Union and Russia in the course of half a century. Special emphasis is given to the activities of Rostislav Alekseyev, who has played an enormous role in the development of this new technology. Ekranoplans developed by several other major design bureaus, notably those led by Sukhoi, Bartini and Beriyev, are also considered. Economic and political transformations following the break-up of the Soviet Union led to the emergence of privately-owned design bureaus and firms that are now pursuing the development of WIG aircraft in Russia, given the lack of interest on the part of the military and the state in this branch of transport technology. This new edition has been fully updated to include unpublished photos and diagrams and examples of similar technology being developed in countries outside of Russian, including the USA, Germany and China. This is a welcome update to a book regarded as the definitive work on these unusual and exciting aircraft.

In the last half-century, high-speed water transportation has developed rapidly. Novel high-performance marine vehicles, such as the air cushion vehicle (ACV), surface effect ship (SES), high-speed monohull craft (MHC), catamaran (CAT), hydrofoil craft (HYC), wave-piercing craft (WPC) and small water area twin hull craft (SWATH) have all developed as concepts, achieving varying degrees of commercial and military success. Prototype ACV and SES have achieved speeds of 100 knots in at calm con- tions; however, the normal cruising speed for commercial operations has remained around 35–50 knots. This is partly due to increased drag in an average coastal s- way where such craft operate services and partly due to limitations of the propulsion systems for such craft. Water jets and water propellers face limitations due to c- itation at high speed, for example. SWATH are designed for reduced motions in a seaway, but the hull form is not a low drag form suitable for high-speed operation. So that seems to lead to a problem – maintain water contact and either water propulsion systems run out of power or craft motions and speed loss are a problem in higher seastates. The only way to higher speed would appear to be to disconnect completely from the water surface. You, the reader, might respond with a question about racing hydroplanes, which manage speeds of above 200 kph. Yes, true, but the power-to-weight ratio is extremely high on such racing machines and not economic if translated into a useful commercial vessel.

This book is dedicated to the memory of a distinguished Russian engineer, Rostislav E. Alexeyev, who was the first in the world to develop the largest 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 to the underlying solid surface (ground). This case is interesting for practical purposes because both the aerodynamic and the economic efficiency of the system near the ground are most pronounced. Use of the method of matched asymptotic expansions enables closed form solutions for the aerodynamic characteristics of the wings-in-ground effect. These can be used for design, identification, and processing of experimental data in the course of developing ground effect vehicles. The term extreme ground effect, widely used through out the book, is associated with very small relative ground clearances of the order of 10% or less. The theory of a lifting surface, moving in immediate proximity to the ground, represents one of the few limiting cases that can be treated analytically. The author would like to acknowledge that this work has been influenced by the ideas of Professor Sheila E. Widnall, who was the first to apply the matched asymptotics techniques to treat lifting flows with the ground effect. Saint Petersburg, Russia February 2000 Kirill V. Rozhdestvensky Contents 1.

This book details the efforts to build a large naval vessel capable of traveling at one hundred knots. It is the first book to summarize this extensive work from historical and technical perspectives. It explores the unique principles and challenges in the design of high-speed marine craft. This volume explores different hull form concepts, requiring an understanding of the four forces affecting the lift and the drag of the craft. The four forces covered are hydrostatic (buoyancy), hydro-dynamic, aerostatic, and aerodynamic. This text will appeal to naval researchers, architects, graduate students and historians, as well as others generally interested in naval architecture and propulsion.

Sweeping away the "red herrings" and spurious details invented in the West between 1950 and 1970, this exhaustive volume can be offered to the public with the knowledge that it documents the true histories of some 1000 aircraft types. Much of what was believed to be fact has been proven wrong in various degrees, and it can confidently be claimed that no book in the history of aviation has ever contained so much new information. The volume is prefixed by sections on aircraft designations, engines, air launched weapons and much more - this really is the definitive work on Russian aircraft.
