The diameters of the main rotor and tail rotor of a single-engine helicopter are 7.67 m and 1.05 m, respectively. The respective rotational speeds are 456 rev/min and 4,130 rev/min. Calculate the speeds of the tips of both rotors. main rotor tail rotor Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s Compare these speeds with the speed of sound, 343 m/s. vmain rotor / vsound = vtail rotor / vsound =
