Aerospace engineering is a discipline of engineering that is related to the design, construction and development of aircraft and spacecrafts. It is classified into two main branches termed as aeronautical engineering and astronautical engineering. It uses tools from several other disciplines including aerodynamics, avionics, propulsion, materials science and structural analysis. Astronautical engineering deals with designing, developing and manufacturing of spacecrafts. Aeronautical engineering is concerned with the study, design, testing and manufacturing of flight capable machines and other aircraft. Few of the major elements of aerospace engineering are radar cross-section, fluid mechanics, electro-technology and solid mechanics. This book unfolds the innovative aspects of aerospace engineering which will be crucial for the progress of this field in the future. The topics included herein are significant and bound to provide incredible insights to readers. This book will serve as a resource guide to the readers in keeping pace with the rapid changes in this field.
