Aerospace Engineering Principles
Why things fly, and what changes when the air thins out
Flight is an equilibrium problem with a fluid involved. This track builds from how a wing makes lift, through the atmosphere it works in, to the propulsion and control that make a vehicle go where you point it.
Flight
Lift, atmosphere, propulsion and stability
- Lift, Drag & AerofoilsFreeHow a wing makes lift, why it stops working past a certain angle, and the two kinds of drag that fight each other.14 min
- The Atmosphere & AltitudeFreeAir gets thinner with height, and almost every aerospace consequence follows from that one fact.13 min
- Propulsion & ThrustFreeThrust is momentum thrown backwards. Why big slow propellers beat small fast ones, and what a rocket does differently.14 min
- Stability & ControlFreeThe difference between an aircraft that returns to level by itself and one that needs a computer to stay pointing forwards.14 min
