mass if m = 0.5 kg at a distance of e = 0.15m from the axis of rotation, as shown in Fig.3.55.
The tail section has a length of 4 m, a mass of 240 kg, a flexural stiffness (EI) of 2.5 MN-m2, and a damping ratio of 0.15. The mass of the tail rotor blade, including their drive system, is 20 kg.
Determine the forced response of the tail section then the blades rotate at 1500 rpm.
