Aerospace Engineering is an interdisciplinary branch that deals with aircraft and spacecraft design, development, and manufacture. The major topics are aerodynamics, which examines the flow of air around vehicles, and propulsion, which deals with motors employed in air and space travel. Structural analysis and materials science deal with the design of efficient and robust structures for aircraft and spacecraft, making them able to perform in extreme environments.
Other key topics are flight mechanics, which involves the forces and motions on an aircraft or a spacecraft, and avionics, which involves the electronic devices utilized for control and navigation. Control systems are necessary in flight stability and performance. Space technology study also involves rocket science and satellite design. Aerospace engineers design both civilian and military use, and the discipline is fundamental to the further development of space and air travel, and many times are also working together on leading-edge research.
