Aerospace engineering designs vehicles and systems that move through atmospheres and space. The dominant physics changes with flight regime, but every mission still has to close forces, energy, structure, control, environment, reliability, operations, and verification into one workable system.
Start with one deliberately narrow flight model. Once speed, angle, lift demand, drag demand, and flow regime are linked, the rest of aerospace engineering can be layered around what that toy model omits.
Adjust a generic wing's relative airspeed and angle of attack. The model compares normalized lift tendency with a fixed weight demand. It is intentionally not an airfoil-performance calculator.
The toy wing is in its attached-flow region.
Can you reach near-trim at a lower angle by increasing speed? What happens if you keep increasing angle after the model's separation threshold?

Aerospace is not cleanly split into “airplane physics” and “space physics.” Launch, high-speed flight, entry, rotorcraft, atmospheric vehicles, spacecraft, and mixed missions move through overlapping regimes with different dominant constraints.
A lighter structure can change control response; a new trajectory can change thermal load; extra redundancy can change mass and power; a propulsion decision can reshape the entire mission. Aerospace design lives in those couplings.
Pressure, shear, compressibility, boundary layers, geometry, motion, and atmospheric conditions interact across very different speed and altitude regimes.
Air-breathing engines, rockets, electric propulsion, propellers, rotors, and other systems solve different mission and environment problems with different constraints.
Aerospace structures trade mass, stiffness, strength, fatigue, buckling, vibration, thermal expansion, protection, inspectability, and damage tolerance.
Sensors, estimation, actuators, feedback, flight software, navigation references, redundancy, and failure handling connect desired motion to actual motion.
Orbits, transfers, gravity assists, rendezvous, attitude dynamics, propulsion events, and reference frames determine trajectories once the space environment dominates.
Mass, power, thermal control, communication, reliability, operations, manufacturing, human factors, environment, cost, and margins interact across the full lifecycle.
