Prt 1 1. Aircraft engine produce thrust backwards and propel the aircraft forward 2. The smoothness of the skin 3. Is a layer of air from the aircraft to the closest layer of air with true air speed 4. Tendency of one layer of air to stick to the skin of the aircraft 5. Laminar - smooth airflow at the aircraft wing Turbulence - air flow ceases to be laminar at a certain point Transition flow - the point where the laminar airflow turns to turbulence 6. When velocity is high dynamic pressure is high and static pressure is low and vice versa Lift - upward force Upwash - the point where the air separated at the leading edge Downwash - the point where the air separated at the trailing edge Airfoils - the shape of the wing that allows the aircraft to produce lift 8. Density,coefficient of lift,velocity and wing area
