Short Description
Aerospace Propulsion Systems is a unique book that focuses on propulsion systems commonly used in aerospace vehicles today; e.g., rockets, piston aero engines, gas turbine engines, ramjets, and scramjets. Ward introduces each system, imparting an understanding of basic engineering principles, describing key functionality mechanisms used in past and modern designs, and providing guidelines to assist students design their own projects. The author presents a balance of theory, fundamental performance analysis, and design. The book is specifically targeted to students or professionals new to the field and features an intuitive, systematic format to enhance learning.
Aerospace Propulsion Systems is a unique book focusing on each type of propulsion system commonly used in aerospace vehicles today: rockets, piston aero engines, gas turbine engines, ramjets, and scramjets. Dr. Thomas A. Ward introduces each system in detail, imparting an understanding of basic engineering principles, describing key functionality mechanisms used in past and modern designs, and provides guidelines for student design projects. With a balance of theory, fundamental performance analysis, and design, the book is specifically targeted to students or professionals who are new to the field and is arranged in an intuitive, systematic format to enhance learning.
* Covers all engine types, including piston aero engines
* Design principles presented in historical order for progressive understanding
* Focuses on major elements to avoid overwhelming or confusing readers
