# Maybe they do.
The UH-60, aka the Black Hawk, is jet-powered. It's possible that it has afterburners.

# Nope.
A helicopter uses a jet engine differently. It doesn't just sit in the back and blow out hot gas...
There would be no point in a helicopter with an afterburner. Though plenty of helicopters are jet engine powered.

gas turbine...

# a jet engine is
a type of gas turbine. all it requires is that hot air resulting from combustion of the propellant be processed by a compressor in producing the motive force.

# Wrong.
The fastest helicopter - the British-built Lynx - utilizes after-burner thrust to increase forward motion. It's part of the design that allows it to top 250mph, if my memory serves.
