RATOG for Helicopters
While re-reading Winkle Brown's Wings On My Sleeve I came across a reference to US helicopters using vertical rocket assisted take off gear during high altitude operations during the Korean conflict. Did other countries use this? Did we? Any comments or experiences to relate? Photos? I'd imagine it would kick up a lot of debris from the ground, given that the rocket nozzles would only be a few feet above the surface.

Just a quick look around Google yielded this item as a reference?
Sounds like it was a recipe for disaster.. Jet Assisted Takeoff for helicopters IG |
Interestingly, the extra thrust was used to assist acceleration to the point where translational lift was generated sooner than in direct lift. Sounds vey dodgy and was proved to be so.

In Korea they used Rocket on Rotor (ROR)

I remember seeing the Napier HTP liquid rocket system on a Saro Skeeter's rotor tips flying out of Luton in the mid 50's. It demonstrated a spectacular vertical climb rate (with associated firework-like noise and vapour streams! ). |
The Fairey Jet Gyrodyne prototype can be seen in the museum at Woodley: https://museumofberkshireaviation.co...s/gyrodyne.htm Apparently it was a bit noisy and didn't make it into production.
