The flybar has a weight or paddle (or both for added stability on smaller helicopters) at each end to maintain a constant plane of rotation. Through mechanical linkages, the stable rotation of the bar mixes with the swashplate movement to damp internal (steering) as well as external (wind) forces on the rotor.
The Flybar is a modification of the traditional pogo stick design which allows riders to propel themselves up to a world record 8 feet 6 inches into the air ...
In operation, propellers and rotors are generally spinning, but could be immersed in a stationary fluid. Thus the tip speed is placed in the denominator so the advance ratio increases from zero to a positive non-infinite value as the velocity increases. Wind turbines use the reciprocal to prevent infinite values since they start stationary in a ...
This quick response can make the model unnecessarily difficult to fly. For this reason, most model helicopters either have a flybar or electronic stabilizing equipment. To reduce mechanical complexity and increase precision of the control of the swashplate some model helicopters use cyclic/collective pitch mixing.
Heading angle σ: angle between north and the horizontal component of the velocity vector, which describes which direction the aircraft is moving relative to cardinal directions. Flight path angle γ: is the angle between horizontal and the velocity vector, which describes whether the aircraft is climbing or descending.
In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.
Flybar's Bumper Car certainly seem like action-packed fun in a box, but not everyone's on-board with this latest find. For starters, it's worth noting that the 175-pound capacity is limiting.
Figure 1: Velocity v and acceleration a in uniform circular motion at angular rate ω; the speed is constant, but the velocity is always tangential to the orbit; the acceleration has constant magnitude, but always points toward the center of rotation.
