I was wondering, the tips of the rotors does that cut down the chopping effect of the boom?

Thank you everyone@Donald the blade tips quite the sound of the rotors. It took 4 months to build the Beast.

I love models that leap off the plinth at you, and this one certainly is striking. 🙂

I was told, don't know if it's true, that the popping sound of the rotors is the blades breaking the sound barrier, is that true? Thanks

Clifford Keesler Author
Yes, s correct. The blade tips go supersonic and the popping is actually mini sonic booms.

Donald, The main rotor blade tips don't reach the speed of sound but the tail rotor blades do. What you are describing is called blade slap. The primary cause of that 'popping' noise is a rotor blade flying through the vortex of the blade before it. It's usually most prominent when the pilot is pulling a lot of power and descending. Basically, the rotor disk is flying in it's own dirty air. 🙂

Thank you all. Kerry you are correct, I had a senior moment. I should be able to remember that stuff since I flew the Damn things.LOL. I remember we used to put our Huey's in a decent and pull power and make the blades pop at night when shooting practice approaches. Let the civillians know we were out there protecting them.

Clifford, I am guilty of copying some information I found on Wikkipedia mate, but I also remember seeing something of the subject on a documentary about how the rotor blades are constructed, so if I sound like a know it all, I apologise mate. :-/

Too bad they didn't know about the rotors tips in Vietnam would of been nice to see!

Clifford, did it really matter if the NVA heard the chop? I hoped they did

Thank you Mats and Ulf. @Donald, no it didn't really matter. The US troops loved hearing it, they knew the calavry was coming. LOL.
