Introduction To Propulsion Systems For Propeller-driven Small And ...

This book is designed for a one-semester elective course for aerospace engineering and mechanical engineering students focused on propeller-driven propulsion systems for small and micro unmanned aerial vehicles. The material presented is based on basic knowledge in thermodynamics, fluid mechanics, and heat transfer.The book introduces readers to the basic principles of propulsion systems, and their performance at different altitudes. It outlines the variety of possible alternative propulsion systems as reflected in the literature. The book includes 11 chapters devoted to altitude atmospheric conditions, general principles of generating thrust, propellers' performance, four- and two-stroke cycle engines, gas exchange and combustion processes in Internal Combustion Engines (ICEs), engines' testing, critical limitations of scaling down of ICEs, electric motors, batteries, and alternative energy storages.The book is rich in original well-designed diagrams and detailed equations development to ease understanding. Each chapter includes some comprehension questions, homework exercises, and selected major references for further reading.
