A v1 0=constant O X x1 Figure 2: The CH-53E Super Stallion (left) and simplified diagram (right) Question 2: 25 points The rotor blades of a CH-53E Super Stallion helicopter are 11m long and rotating at a constant angular velocity of of 179 rpm. The helicopter is flying trimmed and level at a speed of 62 m/s, while accelerating at 5 m/s, as sketched in the figure. Determine the velocity and acceleration of point A, which is the outermost tip of one of the blades (with respect to the ground), when 0 = 7/4. The reference frames defined in Figure 2 are as follows: Oryz is fixed to the ground, while Briyiz, is fixed to the center of the rotor system. Note: these values are realistic for this type/model/series of helicopter in cruise
