Aerospace engineering is a domain of engineering that focuses on the development of aircraft and spacecrafts. It deals with the interaction between technological disciplines like aerodynamics, propulsion, avionics, materials science, structural analysis and manufacturing. It has two sub divisions namely aeronautical engineering and astronautical engineering. It deals with the integration of various components that make up aerospace vehicle's subsystems and its lifecycle. The subsystems comprise of aerospace bearings, thermal control, life support, power, communications, etc. It focuses on designing, assembling, developing and testing aircraft and aerospace products. The aim of this field is to assess the cost and feasibility, determine quality standards, and examine malfunction and damage. This book discusses the fundamentals as well as modern approaches of aerospace engineering. Also included herein is a detailed explanation of the various concepts and applied principles of aerospace engineering. It is a vital tool for all researching and studying in this field.
