Internal Combustion Processes of Liquid Rocket Engines


Book Description

This book concentrates on modeling and numerical simulations of combustion in liquid rocket engines, covering liquid propellant atomization, evaporation of liquid droplets, turbulent flows, turbulent combustion, heat transfer, and combustion instability. It presents some state of the art models and numerical methodologies in this area. The book can be categorized into two parts. Part 1 describes the modeling for each subtopic of the combustion process in the liquid rocket engines. Part 2 presents detailed numerical methodology and several representative applications in simulations of rocket engine combustion.

Combustion Instabilities in Liquid Rocket Engines


Book Description

This is the first book in the literature to cover the development and testing practices for liquid rocket engines in Russia and the former Soviet Union.Combustion instability represents one of the most challenging probelms in the development of propulsion engines. A famous example is the F-1 engines for the first stage of the Saturn V launch vehicles in the Apollo project. More than 2000 full engine tests and a vast number of design modifications were conducted to cure the instability problem.This book contains first-hand information about the testing and development practices for treating liquid rocket combustion-instability problems in Russia and the former Soviet Union. It covers more than 50 years of research, with an emphasis placed on the advances made since 1970.The book was prepared by a former R&D director of the Research Institute of Chemical Engineering, NIICHIMMASH, the largest liquid rocket testing center in the world, and has been carefully edited by three well-known experts in the field.

Liquid Rocket Engine Combustion Instability


Book Description

Annotation Since the invention of the V-2 rocket during World War II, combustion instabilities have been recognized as one of the most difficult problems in the development of liquid propellant rocket engines. This book is the first published in the United States on the subject since NASA's Liquid Rocket Combustion Instability (NASA SP-194) in 1972. In this book, experts cover four major subject areas: engine phenomenology and case studies, fundamental mechanisms of combustion instability, combustion instability analysis, and engine and component testing. Especially noteworthy is the inclusion of technical information from Russia and China--a first.




Advanced Engine Development at Pratt & Whitney


Book Description

FROM THE PREFACE: This book celebrates the wonderful projects on which we worked at Pratt & Whitney during the almost magical quarter century bounded by World War II and the competition to develop the Space Shuttle engine. Some of the work has never been described until this book because of stringent security classifications that are now lifted. This book is about the almost unbelievable engines and the dedicated group of people who made the engines real. Most of these unique projects were not the daily 'bread and butter' for Pratt & Whitney and thus were free from much of the survival pressure that typically surrounds that work. Instead, they were driven by the challenge of attempting things that had never been done. Two lasting discoveries that came from the work of the group were the RL10 hydrogen rocket engine, which has been used to launch most large satellites over the past half-century, and the development of the technology for the high-pressure staged combustion rocket engine used in the Space Shuttle.CONTENTS INCLUDE: Ramjets - The Early Days at the Research Laboratory; T57 - The Largest Turboprop; Liquid Hydrogen and the 304 Engine - Suntan; RL10 - My Only Moneymaker; High-Pressure Rockets - A Decade and One-Half Billion Dollars; Boost Glide and the XLR129-Mach 20 at 200,000 Feet; XLD-1 Gas Dynamic Laser; The Space Shuttle Engine; A Cry for Help.




Stable Combustion Processes in Liquid Propellant Rocket Engines


Book Description

Information is presented on the combustion processes necessary for successful analytical modeling of liquid-propellant rocket engine combustion during stable operation. Theoretical and experimental results of single-propellant droplet combustion and their application in spray-combustion analyses are reviewed. Propellant-spray formation and droplet-size distributions from particular rocket injector types are considered. Several assumptions concerning the propellant combustion processes are examined and the experimental evidence necessary for confirming the model predictions is discussed. Recent experimental data, found sufficient for approximate model verification, are shown to be useful for guiding the development of an analytical bipropellant combustion model without the necessity of making simplifying and restrictive assumptions. A description of a new combustion model is given, which is based on detailed spatial accounting of the combustion field for each particular injector-chamber configuration and propellant combination.
