Flight vehicles are subjected to demanding conditions such as those produced by extreme changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components.
Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, propulsion, avionics, materials science, structural analysis and manufacturing.
The interaction between these technologies is known as aerospace engineering. Because of the number of disciplines involved, aerospace engineering is carried out by teams of engineers, each having their own specialised area of expertise.
The development and manufacturing of a modern flight vehicle is an extremely complex process and demands careful balance and compromise between abilities, design, available technology and costs.
Aerospace engineers design, test, and supervise the manufacture of aircraft, spacecraft, and missiles. Aerospace engineers develop new technologies for use in aviation, defense systems, and space.
