  2. Aircraft principal axes - Wikipedia

    en.wikipedia.org/wiki/Aircraft_principal_axes

    The position of all three axes, with the right-hand rule for describing the angle of its rotations. An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail.

  3. Rotation (aeronautics) - Wikipedia

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

    Rotation is begun at the speed known as V R. Rotation at the correct speed and to the correct angle is important for safety reasons and to minimise takeoff distance. [1] After rotation, the aircraft continues to accelerate until it reaches its liftoff speed V LO, at which point it leaves the runway.

  4. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    y b axis - perpendicular to the x b,z b-plane, positive determined by the right-hand rule (generally, positive out the right wing) Wind frame Origin - airplane center of gravity; x w axis - positive in the direction of the velocity vector of the aircraft relative to the air; z w axis - perpendicular to the x w axis, in the plane of symmetry of ...

  5. Flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Flight_dynamics

    Flight dynamics is the science of air-vehicle orientation and control in three dimensions. The critical flight dynamics parameters are the angles of rotation with respect to the three aircraft's principal axes about its center of gravity, known as roll, pitch and yaw.

  6. Axes conventions - Wikipedia

    en.wikipedia.org/wiki/Axes_conventions

    For positive y- and z-axis, we have to face two different conventions: In case of land vehicles like cars, tanks etc., which use the ENU-system (East-North-Up) as external reference (World frame), the vehicle's (body's) positive y- or pitch axis always points to its left, and the positive z- or yaw axis always points up. World frame's origin is ...

  7. Euler angles - Wikipedia

    en.wikipedia.org/wiki/Euler_angles

    ] In four dimensions and above, the concept of "rotation about an axis" loses meaning and instead becomes "rotation in a plane." The number of Euler angles needed to represent the group SO( n ) is n ( n − 1)/2 , equal to the number of planes containing two distinct coordinate axes in n -dimensional Euclidean space.

  8. Yaw (rotation) - Wikipedia

    en.wikipedia.org/wiki/Yaw_(rotation)

    A yaw rotation is a movement around the yaw axis of a rigid body that changes the direction it is pointing, to the left or right of its direction of motion. The yaw rate or yaw velocity of a car, aircraft, projectile or other rigid body is the angular velocity of this rotation, or rate of change of the heading angle when the aircraft is ...

  9. Spin (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Spin_(aerodynamics)

    Spin — an aggravated stall and autorotation. In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. [1]
