I have seen radomes atop the rotors--any tiny cockpit designs to go there instead?

U.S. NAVY HELICOPTER ESCAPE CAPSULE

Shuttle SRBs were released using explosive bolts. Perhaps those could blast the blades clear for normal ejection seats.

@moin1900 : thank you for sharing. Great footage.

The explosive blast assisted chute opening is something I have never seen before. Sounds interesting.

For the rest of the system, I am pretty sure no Marines or Naval aviator were consulted prior to the study (/joke). Imagine their disarray having to fly such system in combat where one single lucky bullet can activate the system, Also the ground crew having to tightly park a dozen of prone to blast helicopters in a ship hangar and seemingly crawl daily around for their maintenance.

Isn't that the system used on the Ka-50/52?

 

[publiusr]

Perhaps…I wonder if it might corrode

 

[Scott Kenny]

Isn't that the system used on the Ka-50/52?

It is. IIRC they pop the upper rotor first, then the lower rotor as soon as the upper blade roots are past the tips of the lower blades.

I'd hate trying to sync everything up through a rotating connection like a rotor mast. either electronically or mechanically (well, detonation-train, with probably two rings of detcord touching each other)

 

[publiusr]

No side ejection systems?

 

[Scott Kenny]

No side ejection systems?

Human bodies don't like sudden g-loads in that direction. Straight up or straight down is much safer, and people still break their backs on ejection.

 

[Nik]

Wasn't there a system which launched a cable up through blades to cut them close to hub, so they flew clear moments before crew ejected ??

 

[Arjen]

Yep.
