Class
    Foam::fv::rigidBodyPropellerDisk

Description
    Disk momentum source derived from Foam::fv::propellerDisk with support
    for motion of the body the propeller is attached to.

Usage
    Example usage:
    \verbatim
    diskSource
    {
        type            rigidBodyPropellerDisk;

        normal          (1 0 0);    // Normal direction of the propeller

        n               26.03;      // Rotation speed [1/s]

        dPropeller      0.203;      // Propeller diameter
