In summary, the conversation is about designing a rotorcraft with a tilting rotor. The force needed to tilt the rotor depends on its moment of inertia and angular velocity. The purpose of building a gyroplane is the reason for requiring a tilting rotor. The conversation also suggests doing further research on gyrocopter cyclic, teeter hinge rotor, fully articulated rotor, and consulting an expert on the topic. Various links are provided for more information on the subject.

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 :)

FAQ: Gyroscopic effect on tilting rotor?

What is the gyroscopic effect on tilting rotor?

The gyroscopic effect on tilting rotor is the phenomenon where a spinning rotor on an aircraft causes a force that resists any attempt to change the orientation of the rotor. This effect is due to the conservation of angular momentum.

How does the gyroscopic effect affect the stability of a tilting rotor aircraft?

The gyroscopic effect can greatly impact the stability of a tilting rotor aircraft. When the rotor is spinning, it creates a strong gyroscopic force that can resist any changes in the aircraft's orientation. This can make it more difficult to control and maneuver the aircraft.

Can the gyroscopic effect be counteracted on a tilting rotor aircraft?

Yes, the gyroscopic effect can be counteracted on a tilting rotor aircraft. One way to do this is by using a fly-by-wire system, where computers and control systems are used to compensate for the gyroscopic forces and maintain stability.

Are there any advantages to using the gyroscopic effect on a tilting rotor aircraft?

Yes, there are some advantages to using the gyroscopic effect on a tilting rotor aircraft. The gyroscopic forces can help to stabilize the aircraft and make it more resistant to turbulence. It can also help with maneuverability and precision control in certain situations.

How does the gyroscopic effect differ on a tilting rotor aircraft compared to a fixed-wing aircraft?

The gyroscopic effect on a tilting rotor aircraft is similar to that of a fixed-wing aircraft in terms of resisting changes in orientation. However, the gyroscopic forces are much stronger on a tilting rotor aircraft due to the high speed and large mass of the spinning rotor. This can make it more challenging to control the aircraft.
