Aerospace refers to the human endeavor to fly in space or the earth's atmosphere using science and engineering. Aerospace technology covers the design and operation of aircraft and spacecrafts. Aerospace can be further divided into the two main categories- aeronautics and astronautics. The study of aerospace technology falls under the domain of aerospace engineering. Functional safety is a crucial aspect of aerospace. Some of the crucial areas of study in this field are radar cross-section, fluid mechanics, astrodynamics, propulsion, aeroacoustics, etc. The ever-growing need of advanced technology is the reason that has fueled the research in the field of aerospace technology in recent times. This book is a compilation of topics that discuss the most vital concepts and emerging trends in this field. It attempts to understand the multiple branches that fall under this discipline and how such concepts have practical applications. It will serve as a reference to a broad spectrum of readers.
