Zero-lift drag coefficient

Index Zero-lift drag coefficient

In aerodynamics, the zero-lift drag coefficient C_ is a dimensionless parameter which relates an aircraft's zero-lift drag force to its size, speed, and flying altitude. [1]

Aerodynamics

Aerodynamics (ἀήρ aero (air) + δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing.

See Zero-lift drag coefficient and Aerodynamics

Aspect ratio (aeronautics)

In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord.

See Zero-lift drag coefficient and Aspect ratio (aeronautics)

Cube root

In mathematics, a cube root of a number is a number such that.

Drag (physics)

In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the relative motion of any object, moving with respect to a surrounding fluid. Zero-lift drag coefficient and drag (physics) are aerodynamics.

See Zero-lift drag coefficient and Drag (physics)

Drag coefficient

In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. Zero-lift drag coefficient and drag coefficient are drag (physics).

See Zero-lift drag coefficient and Drag coefficient

Force

A force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces.

See Zero-lift drag coefficient and Force

Horsepower

Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors.

See Zero-lift drag coefficient and Horsepower

Lift coefficient

In fluid dynamics, the lift coefficient is a dimensionless quantity that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area. Zero-lift drag coefficient and lift coefficient are aerodynamics.

See Zero-lift drag coefficient and Lift coefficient

Lift-induced drag

Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. Zero-lift drag coefficient and lift-induced drag are drag (physics).

Lockheed Constellation

The Lockheed Constellation ("Connie") is a propeller-driven, four-engined airliner built by Lockheed Corporation starting in 1943.

North American P-51 Mustang

The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts.

Oswald efficiency number

The Oswald efficiency, similar to the span efficiency, is a correction factor that represents the change in drag with lift of a three-dimensional wing or airplane, as compared with an ideal wing having the same aspect ratio and an elliptical lift distribution.

See Zero-lift drag coefficient and Oswald efficiency number

Parasitic drag

Parasitic drag, also known as profile drag, is a type of aerodynamic drag that acts on any object when the object is moving through a fluid. Zero-lift drag coefficient and Parasitic drag are drag (physics).

See Zero-lift drag coefficient and Parasitic drag

Propulsive efficiency

In aerospace engineering, concerning aircraft, rocket and spacecraft design, overall propulsion system efficiency \eta is the efficiency with which the energy contained in a vehicle's fuel is converted into kinetic energy of the vehicle, to accelerate it, or to replace losses due to aerodynamic drag or gravity. Zero-lift drag coefficient and Propulsive efficiency are aerodynamics.

Slug (unit)

The slug is a derived unit of mass in a weight-based system of measures, most notably within the British Imperial measurement system and the United States customary measures system.

See Zero-lift drag coefficient and Slug (unit)

Sopwith Camel

The Sopwith Camel is a British First World War single-seat biplane fighter aircraft that was introduced on the Western Front in 1917.

See Zero-lift drag coefficient and Sopwith Camel

Wing loading

In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.

See Zero-lift drag coefficient and Wing loading

World War I

World War I (alternatively the First World War or the Great War) (28 July 1914 – 11 November 1918) was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers.

See Zero-lift drag coefficient and World War I

World War II

World War II or the Second World War (1 September 1939 – 2 September 1945) was a global conflict between two alliances: the Allies and the Axis powers.
