How to minimize torque when using rotators as engines

8,272 Sockdragger  one month ago

So here's my problem: I am using a rotator to drive a disk, may be later a wing assembly and as soon as I add something to the rotator hub, even if I flip the rotator and let the body rotate while thr hub stands still, I immediately have to deal with torque so massive it basically turns my test bed almost as fast as it turns my rotator.[

Take a look at my build so far to see what I am talking about

Is there any way to get the torque down to a manageable level, other than build two rotor assemblies and let their torques counteract each other?

May be some secret XML variable to get the assembly's momentum down?

    @Thad23 so my best option so far is not to use just one rotator engine but make a two-engined plane with both rotators counteracting each other. It's a dirty fix and it somehow feels like running away from a good fight, but what the xxxc, if it works, it works

    Building on @OverlordPrime, I've found that the object on the counter-rotator should weigh rough the same as the thing it's countering.

    @Sockdragger counter rotators are the easiest way, if you have stuff with zero mass then one complementary rotator with one zero mass part will do the trick
    On control bases, set slerpMaximumForce, slerpSpring, slerpDamper. Names after slerp are self-explanatory. I used this for a special use case where I also needed a 3D spring. It is a headache

    @hpgbproductions how do you do 'control bases'? I already used XML to set the rotator assembly's mass and drag out 0 that doesn't seem to help.

    Counter rotator. Basically a rotator with same input spinning the other way. Do attach something on it.
    This is the easy way. There are other ways too

    Unfortunately no
    If you want to reduce torque, you can try messing with control bases
