Aerospace Engineering

The study of how air and other gases interact with bodies in motion. It involves analyzing forces such as lift ($L$), drag ($D$), thrust ($T$), and weight ($W$) to design efficient airfoils, wings, and vehicle shapes.

The branch of celestial mechanics that studies the motion of artificial satellites and spacecraft under the influence of gravitational fields, used to plan trajectories, orbits, and interplanetary transfers.

The mechanisms that generate thrust to move aerospace vehicles, including turbojets, turbofans, ramjets, scramjets, solid and liquid rocket engines, and emerging electric propulsion systems.

The process of determining the effects of loads and stresses on aerospace structures, ensuring they can withstand aerodynamic forces, thermal loads, vibrations, and fatigue over their operational lifetime.

The integrated systems of sensors, computers, actuators, and control surfaces that manage an aircraft's or spacecraft's attitude, trajectory, and stability during flight.

The application of thermodynamic principles to analyze and optimize energy conversion in propulsion systems, including the Brayton cycle for jet engines and the Tsiolkovsky rocket equation ($\Delta v = v_e \ln\frac{m_0}{m_f}$) for space vehicles.

Engineered materials made from two or more constituent materials with significantly different properties that, when combined, produce a material with superior strength-to-weight ratios ideal for aerospace applications.

The electronic systems used in aircraft and spacecraft, including navigation, communications, flight management, radar, and sensor systems that enable safe and efficient operations.

The engineering challenge of protecting spacecraft from extreme heating during atmospheric re-entry, where temperatures can exceed $1{,}650$ °C due to aerodynamic compression and friction.

The use of numerical methods and algorithms to solve and analyze fluid flow problems, enabling engineers to simulate aerodynamic behavior digitally before building physical prototypes.
