Aerospace Engineer in 1919: Streamlining, jets and a science of high-speed flight

What does an aerospace engineer actually do day to day? Most aerospace engineers specialize in one discipline — aerodynamics, structures, propulsion, or guidance and control — and spend their days running simulations, analyzing test data, and defending design decisions in review meetings. Very few personally build or fly anything; the job is mostly calculation, modeling and coordinating with dozens of other engineers whose work has to fit together exactly.

Do I need a master's degree to become an aerospace engineer? No — a four-year bachelor's degree in aerospace, mechanical or a related engineering field is the standard entry point at most companies and agencies. A master's or PhD becomes useful, and sometimes expected, for research-heavy roles, propulsion specialization, or work at national labs, but most production engineering jobs hire straight from an undergraduate program.

What's the difference between aeronautical and astronautical engineering? Aeronautical engineering covers vehicles that fly within the atmosphere — airplanes, helicopters, drones — relying on aerodynamic lift. Astronautical engineering covers vehicles that operate in or travel through space — rockets, satellites, spacecraft — where orbital mechanics and propulsion in a vacuum matter more than lift. 'Aerospace engineering' is the umbrella term covering both, and most degree programs teach a shared core of each.
