  2. Drag curve - Wikipedia

    en.wikipedia.org/wiki/Drag_curve

    The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.

  3. Trim drag - Wikipedia

    en.wikipedia.org/wiki/Trim_drag

    Trim drag, denoted as Dm in the diagram, is the component of aerodynamic drag on an aircraft created by the flight control surfaces, [1] mainly elevators and trimable horizontal stabilizers, when they are used to offset changes in pitching moment and centre of gravity during flight.

  4. Yaw string - Wikipedia

    en.wikipedia.org/wiki/Yaw_string

    Technically, it measures sideslip angle, not yaw angle, [2] but this indicates how the aircraft must be yawed to return the sideslip angle to zero. It is typically constructed from a short piece or tuft of yarn placed in the free air stream where it is visible to the pilot. [3] In closed-cockpit aircraft, it is usually taped to the aircraft canopy.

  5. 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.

  6. Aerodynamic force - Wikipedia

    en.wikipedia.org/wiki/Aerodynamic_force

    The force created by propellers and jet engines is called thrust, and is also an aerodynamic force (since it acts on the surrounding air). The aerodynamic force on a powered airplane is commonly represented by three vectors: thrust, lift and drag. [3]: 151 [1]: § 14.2

  7. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    An aircraft is streamlined from nose to tail to reduce drag making it advantageous to keep the sideslip angle near zero, though an aircraft may be deliberately "sideslipped" to increase drag and descent rate during landing, to keep aircraft heading same as runway heading during cross-wind landings and during flight with asymmetric power.

  9. Meredith effect - Wikipedia

    en.wikipedia.org/wiki/Meredith_Effect

    The North American P-51 Mustang makes significant use of the Meredith effect in its belly radiator design. [1]The Meredith effect is a phenomenon whereby the aerodynamic drag produced by a cooling radiator may be offset by careful design of the cooling duct such that useful thrust is produced by the expansion of the hot air in the duct.
