2. Aerodynamic center - Wikipedia

   en.wikipedia.org/wiki/Aerodynamic_center

   The distribution of forces on a wing in flight are both complex and varying. This image shows the forces for two typical airfoils, a symmetrical design on the left, and an asymmetrical design more typical of low-speed designs on the right. This diagram shows only the lift components; the similar drag considerations are not illustrated.

3. Cathy Osgood - Wikipedia

   en.wikipedia.org/wiki/Cathy_Osgood

   Just before moving to Houston in July of 1962, Osgood's job changed to that of aerospace engineer. [2]: 37 Osgood joined the Johnson Space center, NASA, in Houston, [3] and with the help of a live-in nanny and grandparents who were able to help with the care of her three children Osgood determined how to coordinate rendezvous in space. [2]: 37

4. Lift coefficient - Wikipedia

   en.wikipedia.org/wiki/Lift_coefficient

   The section lift coefficient is based on two-dimensional flow over a wing of infinite span and non-varying cross-section so the lift is independent of spanwise effects and is defined in terms of ′, the lift force per unit span of the wing. The definition becomes

5. Lifting-line theory - Wikipedia

   en.wikipedia.org/wiki/Lifting-line_theory

   Lifting line theory supposes wings that are long and thin with negligible fuselage, akin to a thin bar (the eponymous "lifting line") of span 2s driven through the fluid. . From the Kutta–Joukowski theorem, the lift L(y) on a 2-dimensional segment of the wing at distance y from the fuselage is proportional to the circulation Γ(y) about the bar a

6. Load factor (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Load_factor_(aeronautics)

   In both cases the lift vector is the same (as seen by an observer on the ground), but in the latter the vertical axis of the aircraft points downwards, making the lift vector's sign negative. In turning flight the load factor is normally greater than +1. For example, in a turn with a 60° angle of bank the load factor is +2. Again, if the same ...

7. Lift-to-drag ratio - Wikipedia

   en.wikipedia.org/wiki/Lift-to-drag_ratio

   Lift and drag are the two components of the total aerodynamic force acting on an aerofoil or aircraft.. In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air.
