Gyroscopic effect on tilting rotor?

  1. Nov 22, 2008 #1
    Hello folks
    I've been a little confused - I'm currently designing a rotorcraft but I need to be able to predict the force (or torque) I'd need to tilt the rotor.

    What I've done is model the rotor as a simple rigid disc. I've attached the diagram below. what sort of behavior would I get during trying to tilt it in any direction? Please note that the pivot is a ball-socket joint and so it's able to tilt in any direction.

    Thank you

    Have a look at the moment of gyration; http://en.wikipedia.org/wiki/Radius_of_gyration

    The amount of force required to tilt the rotor will be based on its moment of inertia and angular velocity.

    But why would you build a rotor craft with a titling rotor? Whats the point?

    That link simply tells me how to calculate the radius of gyration. Nothing about moments.
    What I'm working on is a gyroplane - hence the requirement for tilting.

    Thanks :)
