Animating helicopter rotor.

Hi all,

I am trying to animate the helicopter rotor. Not able to set the parameter out of range types, as all the settings seems to be disabled.

Hope it help.
Thanks

Thanks again.

You have to Apply the Ease Curve before those options become available. As snowjade mentioned you are probably looking for Out of Range Types.

EDIT: I would recommend placing the rotation inside a list controller. The second controller can be animated in local space and will properly rotate around one axis.

Hi Pixel Monkey,

Actually I didn't get what you said which I have quoted here. Could you please have a look at the max file attached here. The setup is perfectly working for the main rotor, but the same setup on the rear rotor shows some weird animation.

Sorry can't attach the file here , it says the file size is large.

Thanks again.

To fix your file do the following:

  • Select the Tail Rotor
  • Delete the animation
  • Assign a List Controller To Rotation
  • Assign a Euler XYZ to the Available of the List Controller
  • Double Click the Second Euler XYZ in the Rotation List Layers (this makes it active)
  • Animate in Local Coordinate Space along the Y Axis.
Do the same for the Main Rotor.

To do proper rotor animation you would want to convert the maximum rotor rpm (259) to degrees/second, and take into account the gear ration from the tail to main rotor (4.6:1). Those answers were found here.

So your main rotor should rotate -1554 over 30 frames. Your tail rotor should rotate -7140 over 30 frames.

Hope that helps,
-Eric

Thanks Eric for the detailed explanation and also for finding out the exact numbers on the rotation.
I had uploaded the file again which was done as per your instructions, but I feel the rotor rotation is a bit slow compared to the speed of the helicopter. Actually its a flying helicopter and I am not planning to show to the take off and landing.The helicopter comes into the scene from the side.

Here is the link again:
