- Propulsion Systems: Design and function engines that generate thrust.
- Structural Mechanics: Ensuring the structural integrity of aircraft materials under various conditions.
- Avionics: Electronics systems used for navigation, communication, and control.
What is Aerospace Engineering?
In contrast, aerospace engineering covers the development of aircraft and spacecraft that operate beyond Earth’s atmosphere. With roots in both aeronautical and astronautical engineering, this field has expanded rapidly since the mid-20th century with the advent of space exploration. It involves designing, developing, and testing spacecraft, satellites, rockets, and atmospheric vehicles.
Key Areas of Study:
- Orbital Mechanics: Understanding satellite trajectories and planetary motion.
- Propulsion in Vacuum: Developing engines like ion thrusters and rocket propulsion for space travel.
