Estimate the speeds of the tips of both rotors

Reference no: EM13496401

The diameters of the main rotor and tail rotor of a single-engine helicopter are 7.55 m and 1.04 m, respectively. The respective rotational speeds are 441 rev/min and 4,149 rev/min. Calculate the speeds of the tips of both rotors.

main rotor _____ m/s

tail rotor _____ m/s

Compare these speeds with the speed of sound, 343 m/s.

vmain rotor / vsound =

vtail rotor / vsound =
