Kopter / Leonardo AW09

I had not been paying attention to this new type that's been in development, nice to see progress from a few months ago.

It has an interesting sound signature, sounds like a flying power station transformer.

The rear doors will be good for EMS.

Hope it does well, they seem to be well ahead of the HX50.

Looks a tad small for HEMS?

Do the blades rotate the wrong way?
Maybe to attract sales from Eurocopter owners….

Intriging sound indeed, this is a sound characteristic that I think you would hear from a 500 flight by at medium speed but never that lound.
so i assume it has something to do the 5-blades rotor head, on second thought, because of the high pitch it sound like the tail rotor blades have a nasty resonance...

good looking ship, the Arriel 2K and the new cowling nicely packaged

I think it is the fenestron when in lateral flight

Tickle,

There is a thread on the development of this helicopter from when it was originally being developed by Marenco:

Marenco Swiss Helicopter

My 'non aeronautical' feeling is the fuselage is quite short and bluff at its back end. I wonder how that influences flow past the fenestron when in forward flight? But I guess the same could be said of the Hughes 300, Robinson R22 and they work just fine!

I can’t see why that would attract sales when you lift the pedals do the work you just keep it straight

I’m a little surprised they have gone 5 bladed I would have thought that would increase cost. Should make for good performance though.
For an AW she’s a bit ugly.
Nice to see more in this class been developed.

Sorry - I was being facetious, re the “customers” comment.
But the choice of direction is not immediately obvious to me.
