Pardon me for the reincarnation of rather old discussion.
My question is regarding the design of tail rotors in helicopters.Some of the newer designs incorporate the tail rotor in a disc shaped space instead of the rotor being operating in the open.Also the enclosed disc shaped design usually has increased number of blades.
Also the Apache's are a state of the art,well advanced attack helicopter.If this configuration is much more effective than the previous designs.Then why the manufacturers are still opting to continue with the open configuration design on it?
I'll like to attach couple of images of the enclosed and the open configuration respectively for reference.

Thank you.

- What's the advantage of such a configuration?
- Does the arrangement is aimed at lowering the helicopter's acoustic signature and, so, making it stealthier?
- Or is it to save it from being damaged when under attack?
