There is not that much clear difference between them but yes there are some differences here you may find some clarifications.
Aerospace Engineering:
- Aerospace engineering is a broad field that encompasses both aeronautical engineering and astronautical engineering.
- Aerospace engineering includes the design, development, testing, and production of vehicles that operate both within and beyond Earth's atmosphere.
- Aerospace engineers work on projects such as the design and development of airplanes, helicopters, unmanned aerial vehicles (drones), spacecraft, satellites, space launch vehicles, and space exploration systems.
Aeronautical Engineering:
- Aeronautical engineering focuses specifically on the design, development, testing, and production of vehicles that operate within Earth's atmosphere.
- Aeronautical engineers work on projects such as the design and development of airplanes, helicopters, and unmanned aerial vehicles (drones).
Astronautical Engineering:
- Astronautical engineering, also known as space engineering, focuses specifically on the design, development, testing, and production of vehicles that operate beyond Earth's atmosphere.
- Astronautical engineers work on projects such as the design and development of spacecraft, satellites, space launch vehicles, and space exploration systems.
In summary:
- Aerospace engineering includes both aeronautical engineering (vehicles within Earth's atmosphere) and astronautical engineering (vehicles beyond Earth's atmosphere).
- Aeronautical engineering focuses on vehicles within Earth's atmosphere.
- Astronautical engineering focuses on vehicles beyond Earth's atmosphere.
