Whop Whop Whop!

Love the (yeehaw) rope analogy. :up: As for the shock wave, I always thought those came from something on a much larger scale, like coming from an explosion or supersonic motion of a body (like Mach speed); not sure if that would apply to heli rotors. But hey! You might just have something there!

 

Anyhoo, welcome to verticalmag.com, marc. :bye: Congrats on winding down training and best of luck to ya on the job front.

The original Whop Whop Whop was made by three Italian Nuns falling down the stairs in the convent years prior to the invention of 4/5/212 helicopters.

 

I always had a taxi waiting for me at the local airport when flying a 2 by 4 on the Ivory Coast, he could hear me coming ten minutes before I got there.

I see you're at the top of your politically-correct game today, Don. Despite the fact it's a blessed sound , it did not start with three Italian nuns (pinch fer you!).

 

It started with the chop-chop-chop sound made by the two-bladed rotor of the Bell 47/H-13 (used extensively in the Korean War), which led to the heli nickname of "chopper."

 

Personally, I think the whop, whop, whop is quieter than the chop, chop, chop.

The best I have yet heard is a 214 pulling back strapped to an 8 pounder.

Goes form a whop to a chop to a wap to a very serious crack crack.

Impressive heard from inside or out.
