About Aerospace Engineers

Aerospace Engineers design, develop, test, and oversee the production of aircraft, spacecraft, satellites, missiles, and related systems. The discipline divides into aeronautics—aircraft that operate within the Earth's atmosphere—and astronautics, which covers spacecraft and launch vehicles that operate in or travel to space. Aeronautical engineers work on commercial and military aircraft, designing airframes, propulsion systems, avionics, and flight control systems. Astronautical engineers design launch vehicles, spacecraft structures, propulsion, and mission systems for Earth orbit and deep space exploration. Common engineering analyses include aerodynamic analysis using computational fluid dynamics (CFD), structural analysis for fatigue and damage tolerance, propulsion performance modeling, and trajectory design. Aerospace engineers must navigate extensive regulatory frameworks—FAA certification for commercial aviation, NASA and DoD requirements for space and defense systems. System engineering discipline is central to managing the complexity of aerospace systems, which must meet simultaneously demanding requirements for safety, performance, weight, and cost. They often hold clearances for defense work. ABET-accredited aerospace engineering degrees are the standard educational foundation.
