I’ve always wondered what those lines are on the canopy. The Harrier has them as well. Are they det cord or something in case of a bail out?

For the Harrier, they are indeed explosives in the case of an ejection. However, ejection-seat based helicopters have not yet come into fruition...

Cool, I always wondered what those were for.

I just realized that ejecting upwards would be a bit problematic if the blades are still there...
Need more coffee.

I am no engineer but I would assume that putting ejection seats on a helicopter might be a BAD idea.

“For improved pilot survivability the Ka-50 is fitted with a NPP Zvezda (transl. Star) K-37-800 ejection seat, which is a rare feature for a helicopter.[20] Before the rocket in the ejection seat deploys, the rotor blades are blown away by explosive charges in the rotor disc and the canopy is jettisoned.[21]”
