Study Notes
Understanding Aircraft Flight and Control
Fixed-Wing Aircraft
- Lift: a force that opposes gravity, necessary to rise from the earth's surface and maintain a constant height
- Gravity: a force that attracts all material objects to the earth, proportional to the object's mass
- Wing design: specific plan forms and aerofoil-shaped cross-sections chosen based on size, weight, and performance requirements of the aircraft
- Wing geometry: typical plan forms, aerofoil cross-sections, and associated terminology (as shown in fig. 1.1)
- Lifting force generation: requires relative movement between the wing and surrounding air
- Practical implementation: the wing is moved through the air due to propulsive thrust from a propeller or turbine
