They design, develop, and test aircraft, spacecraft, and missiles and supervise manufacturing of these products. Aerospace engineers who work with aircraft are considered aeronautical engineers, and those working specifically with spacecraft are considered astronautical engineers. Aerospace engineers develop new technologies for use in aviation, defense systems, and space exploration, often specializing in areas like structural design, guidance, navigation and control, instrumentation and communication, or production methods. They also may specialize in a particular type of aerospace product, such as commercial transports, military fighter jets, helicopters, spacecraft, or missiles and rockets. Aerospace engineers may be experts in aerodynamics, thermodynamics, celestial mechanics, propulsion, acoustics, or guidance and control systems.
Most engineers work in office buildings, laboratories, or industrial plants.
Others may spend time outdoors at construction sites, mines, and oil and gas exploration sites, where they monitor or direct operations or solve onsite problems. Some engineers travel extensively to plants or work sites. Many engineers work a standard 40-hour week. At times, deadlines or design standards may bring extra pressure to a job. When this happens, engineers may work longer hours and experience considerable stress.
