Aerospace engineering is a discipline which is concerned with the manufacturing of aircraft and spacecraft. It is categorised into two main branches, aeronautical and astronautical engineering. It focuses on the designing of the aircraft structure with respect to atmospheric temperature and pressure. It encompasses several distinct fields such as astrodynamics, aeroacaustics, aeroelasticity, propulsion and others. Modern aerospace engineering also implements computer software for aerospace applications such as flight software, ground control software, test and evaluation software, etc. This book discusses the fundamentals as well as modern approaches of aerospace engineering
