Helicopter Downdraft over ocean modifier

I’m experimenting with the ocean modifier and I would like to be able to have the effect of downdraft from the helicopter’s rotors.

I will probably raise the chopper’s height to make more space for the downdraft effect.

Also, I’m reasonably new to blender, so pictures, if you can, would make my life easier :stuck_out_tongue:

Don’t laugh at my shocking attempt at an AH64, I made it ages ago, when I thought I had to create objects from a single shape…

Thanks for the help
