  2. Swing equation - Wikipedia

    en.wikipedia.org/wiki/Swing_equation

    The equation describing the relative motion is known as the swing equation, which is a non-linear second order differential equation that describes the swing of the rotor of synchronous machine. The power exchange between the mechanical rotor and the electrical grid due to the rotor swing (acceleration and deceleration) is called Inertial response.

  3. Rotordynamics - Wikipedia

    en.wikipedia.org/wiki/Rotordynamics

    Rotordynamics (or rotor dynamics) is a specialized branch of applied mechanics concerned with the behavior and diagnosis of rotating structures. It is commonly used to analyze the behavior of structures ranging from jet engines and steam turbines to auto engines and computer disk storage .

  4. Angular displacement - Wikipedia

    en.wikipedia.org/wiki/Angular_displacement

    The angular displacement (symbol θ, ϑ, or φ) – also called angle of rotation, rotational displacement, or rotary displacement – of a physical body is the angle (in units of radians, degrees, turns, etc.) through which the body rotates (revolves or spins) around a centre or axis of rotation.

  5. Dynamic rollover - Wikipedia

    en.wikipedia.org/wiki/Dynamic_rollover

    The critical rollover angle is 5°-8°. Once exceeded, main rotor thrust continues the roll, and recovery via cyclic control is impossible. [1] A helicopter is susceptible to a rolling tendency, called dynamic rollover, when close to the ground, especially when taking off or landing. For dynamic rollover to occur, some factor has to first cause ...

  6. Gyroscope - Wikipedia

    en.wikipedia.org/wiki/Gyroscope

    For example, the spinning rotor may be suspended in a fluid, instead of being mounted in gimbals. A control moment gyroscope (CMG) is an example of a fixed-output-gimbal device that is used on spacecraft to hold or maintain a desired attitude angle or pointing direction using the gyroscopic resistance force.

  7. Six degrees of freedom - Wikipedia

    en.wikipedia.org/wiki/Six_degrees_of_freedom

    Measurement of the six degrees of freedom is accomplished today through both AC and DC magnetic or electromagnetic fields in sensors that transmit positional and angular data to a processing unit. The data is made relevant through software that integrates the data based on the needs and programming of the users. Mnemonics to remember angle names

  9. Rotor (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Rotor_(mathematics)

    A rotor is an object in the geometric algebra (also called Clifford algebra) of a vector space that represents a rotation about the origin. [1] The term originated with William Kingdon Clifford, [2] in showing that the quaternion algebra is just a special case of Hermann Grassmann's "theory of extension" (Ausdehnungslehre). [3]
