This book focuses on fundamental concepts in propulsion—particularly gas dynamics, turbomachinery and combustion—and theoretical and practical design aspects of aircraft engines and thermodynamic aspects and analysis. Its pedagogical format enables readers to learn concepts and problem solving and analysis techniques and then use worked examples to understand their application to practical situations in propulsion. Some exercises use thrust calculations based exclusively on military and commercial aircraft engines. The book also introduces advanced concepts on ramjets and scramjets to facilitate advanced studies in propulsion. Written for undergraduate and first-year postgraduate students in mechanical and aerospace engineering, this book is also useful for scientists and engineers working in aerospace propulsion and gas dynamics.
