Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 2013-03-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Avionic Systems, Second Edition explains the principles and theory of modern avionic systems and how they are implemented with current technology for both civil and military aircraft. The systems are analysed mathematically, where appropriate, so that the design and performance can be understood. The book covers displays and man-machine interaction, aerodynamics and aircraft control, fly-by-wire flight control, inertial sensors and attitude derivation, navigation systems, air data and air data systems, autopilots and flight management systems, avionic systems integration and unmanned air vehicles. About the Author. Dick Collinson has had "hands-on" experience of most of the systems covered in this book and, as Manager of the Flight Automation Research Laboratory of GEC-Marconi Avionics Ltd. (now part of BAE Systems Ltd.), led the avionics research activities for the company at Rochester, Kent for many years. He was awarded the Silver Medal of the Royal Aeronautical Society in 1989 for his contribution to avionic systems research and development.
