The Trent 800 features a 110 inch diameter wide-chord fan, high flow compressors and Full Authority Digital Engine Control (FADEC). Detailed engineering design began in 1988 to meet the propulsion requirements of the Airbus A330 (Trent 700) and Boeing 777 (Trent 800). The Trent first ran in August 1990, and in January 1994 a Trent 800 demonstrated a world record thrust of 106,087 lb. The engine entered service in March 1995 in the Airbus A330. Introduction This book has been written to provide a simple and self-contained description of the working and underlying principles of the aero gas turbine engine. The use of complex formulae and the language of the specialist have been avoided to allow for a clear and concise presentation of the essential facts. Only such description and formulae, therefore, as are necessary to the understanding of the function and the theory of the engine are included. It will be noted that the emphasis in this book is on the turbo-jet engine and that no special part deals with the propeller-turbine engine. This is because the working principles of both engine types are essentially the same. However where differences in function or application do exist, these are described. The aero gas turbine is being continually developed to provide improved performance for each new generation of aircraft; the fourth edition of this book has been revised and expanded to include the latest aero gas engine technology. Rolls-Royce RB183 Mk 555 On 1 April, 1943, Rolls-Royce assumed responsibility for the Power Jets W2B which, a month earlier, had made its first flight in the Gloster E28/39 at 1200lb thrust. Later known as the B23 Welland it was, during April, put through a 100 hr test at the design rating of 1600 Ib thrust. In June, 1943, it flew in a Gloster Meteor at 1400lb thrust. Production Welland-Meteors were in action against V-1 flying bombs in August 1944. Rolls-Royce B23 Welland 1: Basic mechanics Contents Page Introduction 1 Principles of jet propulsion 2 Methods of jet propulsion 3 INTRODUCTION 1. The development of the gas turbine engine as an aircraft power plant has been so rapid that it is difficult to appreciate that prior to the 1950s very few people had heard of this method of aircraft propulsion. The possibility of using a reaction jet had interested aircraft designers for a long time, but initially the low speeds of early aircraft and the unsuitably of a piston engine for producing the large high velocity airflow necessary for the ‘jet’ presented many obstacles.   www.aero.cn 航空翻译 www.aviation.cn 本文链接地址:Rolls.Royce.The.JET.ENGINE
