A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Blades are blown horizontally away from the hub, giving enough time for the most part to allow for ejection.

Does that only work because they don't have a tail rotor?

By destroying the linkages between the blades and the main rotor shaft, the blades will fly away from the rotor shaft on their own due to the rotational force that they are experiencing. Even with a dead engine the rotors will be in autorotation mode and spinning at a high speed. They will fly away in a random direction. The helo itself may pick up some downward speed, depending on the angle of attack it was at and how much lift the rotors were providing in autorotation mode. As long as there is about a second time differential between blade separation and the auto-ejection activation the pilots should be clear of any risk.

It's obvious that the blades fly away - I was thinking what happens if they hit the tail rotor and random stuff happens? However this machine doesn't have one, and is the only one with an ejection system. Is that a requirement for successful helicopter ejection systems? Does the system even work?

I doubt they would hit the tail due to the force of the rotation flinging them aside.

The Russians have outfitted bulldozers with ejection seats. I'm relatively sure they can make them work with helo's.
