  2. Aircraft principal axes - Wikipedia

    en.wikipedia.org/wiki/Aircraft_principal_axes

    The pitch axis (also called transverse or lateral axis), [5] passes through an aircraft from wingtip to wingtip. Rotation about this axis is called pitch . Pitch changes the vertical direction that the aircraft's nose is pointing (a positive pitching motion raises the nose of the aircraft and lowers the tail).

  3. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    The three axes of rotation in an aircraft. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.

  4. Blade pitch - Wikipedia

    en.wikipedia.org/wiki/Blade_pitch

    Blade pitch acts much like the gearing of the final drive of a car. Low pitch yields good low speed acceleration (and climb rate in an aircraft) while high pitch optimizes high speed performance and fuel economy. It is quite common for an aircraft to be designed with a variable-pitch propeller, to give maximum thrust over a larger speed range ...

  5. Rotation (aeronautics) - Wikipedia

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

    An aircraft moves at any given moment in one or more of three axes: roll (the axis that runs the length of the fuselage), pitch (the axis running laterally through the wings), and yaw (the vertical axis around which the front of the aircraft turns to the left or right whilst its rear turns toward the opposite direction).

  6. Pitch - Wikipedia

    en.wikipedia.org/wiki/Pitch

    Pitch (typewriter), the number of characters and spaces in one inch (25.4 mm) of running text; Pitch, the distance between bits in a parallel integrated circuit element such as a register file; Dot pitch in images; Pin pitch, the distance between centers of pins in electronics packaging; Seat pitch, the spacing between seat rows in an aircraft

  7. Longitudinal stability - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_stability

    The longitudinal stability of an aircraft, also called pitch stability, [2] refers to the aircraft's stability in its plane of symmetry [2] about the lateral axis (the axis along the wingspan). [1] It is an important aspect of the handling qualities of the aircraft, and one of the main factors determining the ease with which the pilot is able ...

  8. Variable-pitch propeller (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Variable-pitch_propeller...

    When an aircraft is stationary with the propeller spinning (in calm air), the relative wind vector for each propeller blade is from the side. However, as the aircraft starts to move forward, the relative wind vector comes increasingly from the front. The propeller blade pitch must be increased to maintain optimum angle of attack to the relative ...

  9. Pitching moment - Wikipedia

    en.wikipedia.org/wiki/Pitching_moment

    Pitching moment coefficient is fundamental to the definition of aerodynamic center of an airfoil. The aerodynamic center is defined to be the point on the chord line of the airfoil at which the pitching moment coefficient does not vary with angle of attack, [ 1 ] : Section 5.10 or at least does not vary significantly over the operating range of ...
