Activity 2:- Propeller Parameters * Forward speed: - The rate of movement along the path of flight is known as forward speed. * RPM: - RPM means revolutions per minute. It is defined as the number of revolutions rotated by the propeller per minute. * Mtip: - Mtip is defined as the Mach number at the tip of propeller blade. * Diameter: - Length of the propeller blade from blade root to blade tip is the radius of the propeller blade. Twice to the radius is known as diameter. * Pitch:- The angle between the axis of rotation and the chord of a propeller is known as pitch * Chord distribution along the radius: - the
