I wonder if adding spinning wheels arranged in multiple axis might be simpler ways to counteract the forces. Might be too hard to do it in a safe/lightweight way and spin the wheels fast enough to counteract the forces at play.
To get a strong enough reaction wouldn’t you need very heavy wheels that the airlines would be unlikely to be interested in carrying due to extra fuel use?
I don't think a reaction wheel can do a ton in 100 ms.
I was thinking more of a constantly spinning wheel and conservation of angular momentum but maybe that doesn’t help if most of the motion of turbulence is translational? I’m sure it’s an impractical idea.
You're describing a Control Moment Gyroscope (CMG), famously used on the ISS. They have very high torque output per unit power and mass/volume. They and reaction wheels (fixed axis of rotation) are convenient for spacecraft applications because they don't require an external medium to push against. Aircraft are surrounded by air, so they can use control surfaces instead.
This is used in cruiser missiles for stabilisation
