Aircraft engineering is studied in the engineering field of aeronautical engineering. It studies the design, manufacture and operation of aircrafts. The science of aerodynamics is central to the development of this field. Three broad areas of incompressible flow, compressible flow and transonic flow are widely studied in the branch of aircraft engineering. This book is a compilation of a range of topics that aim to explain the key concepts and principles related to aircraft engineering while also illustrating the modern technological advancements. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included in this book. It aims to serve as a reference to a broad spectrum of readers.
