Tutor in Book's Design of Liquid-Fueled Rocket Engines (Volume 3) - In the various types of rocket missiles, the basic element is the engine. The type of engine is determined basically by the design, over- all dimensions, and flight characteristics of these missiles. The missile's range depends on the type or engine selected, the type of fuel components used in it, and on its design, operational, and other characteristics. It is the object of the present volume to provide students in the higher technical educational institutions and engineering-technical workers with a brief outline of the theory and basic design principles of liquid-fueled rocket engines.
