Experimental aircraft. Could take off like a copter, then during travel the blade would be stopped and used as a wing.

Another experimental.

Anyone want to be the test pilot on this?

It had a small problem with the blades crashing into each other.

Saw this one in a movie, I think a Korean War movie.

Hughes first attempt
XH 17
Rotors had fuel/air pumped THROUGH the rotor, igniting at the tips. So, little rockets pushing the rotors around.
The sound was described as 1,000 artillery shells exploding.
This was post WWII, so they used parts from various aircraft to make the body, to keep the cost down.

10 Incredible Stories Involving Helicopters - Listverse

Here's some good helicopter stories.
I especially liked the #1 story.

Just finished up a week at Ft Drum...Apaches, Chinooks, and Blackhawks abound.

HH 43 Huskie

Rescue chopper

That reminds me of the Soviet KA-27 Helix. They probably copied the Husky.

That reminds me of the Soviet KA-27 Helix. They probably copied the Husky.

While they look a bit similar, kind of like cousins, I'm thinking that's more along the lines of form follows function.
They were both trying to keep the main rotor from spinning the copter around.
Most do it with a tail rotor, controlled through foot petals, and sync'd to the main rotor.
But some tried counter rotating rotors.
The similarities are the counter rotating rotors, and the tail assembly. The cabin looks pretty different, and the Russian one has dual engines.
Course, they were always big on redundancy.
Which is funny, because we eventually "accepted" redundancy, but for different reasons.

Our Huskie was back in the heyday of experimentation. First flight 1953.

Their Kamov had quite a few predecessors. First flight 1973.

I kinda doubt they copied a 20 year old design, that we already abandoned.

Maybe in the abstract way, with the two rotors.

The Soviets fielded the Ka-25 (Hormone) 10 years before the 27.
Granted, maybe the Ka-25 was copied from the Huskie.

Thanks for the info. They have some similarities but not a direct copy. I stand corrected. Perhaps they examined the US design before coming up with their own design based (very loosely) on our design. Likely the KA-25 and not the KA-27 as you said.

That is one big bird. Should be very useful.

Thought I would start this thread to see if there might be any other heli heads on INGO. I never saw these at Ft. Rucker.

Whole lot different paint job on that Hind than the ones I saw in Germany. Always an interesting day when they showed up.

Saw this one in a movie, I think a Korean War movie.

You remember right. Bridge at Toko Ri was the movie.

Thanks. It was on the tip of my tongue.
