The 6th edition of this book is a revision of the leading reference for rocket propulsion courses offered in aerospace engineering departments and in industry. It covers the basic physical principles of rocket propulsion such as nozzle thermodynamics, heat transfer, flight performance and fuel chemistry. It also determines the design rationale of components such as nozzles, fuel chambers, structures and control systems. All rocket types are covered - liquid, solid, hybrid-fuelled and electric propulsion systems. The book contains new chapters on the advantages of liquid and solid propellent rockets, thrust vector control and electric propulsion. New material on plume effects, radiation, noise, electrical interference, smoke and hazards is also included.
