How to drill/cut rills in a part

So I'm fairly new to solidworks and I run into many problems.
So far I managed it to create my own propeller - but I now need to cut rills into the surface of the propeller, like shown in the picture below. I want it over the whole wing and if possible some way of automated.

Any ideas or help would be greatly appreciated. Thank you.

Two options I can think of off the top of my head: You can use a 3d sketch to define a spline for the rills to follow, and then do a swept cut down the length of it. This might take some trial and error to find the right shape to sweep. Alternatively you could define a complex equation driven surface to create the rills.

you try to use insert>fastening feature> vent...
