Hummel - helicopter -

The “Hummel” (”bumble bee”) is a light helicopter for maximum two passengers. It can be used for passenger transport (air taxi), as well as for e.g. emergency transports like organs or units of stored blood and of course for conventional tasks of a helicopter like monitoring (e.g. coast guard, police, army, scientists) and to be mobile. The tandem rotor design guarantees a more efficient aircraft performance as the main-tail rotor design, without wasting fuel.

Wonderful design. I’ve also downloaded your portfolio. Beautiful, inspiring designs all around.
I hope to see a Hummel fly one day.
A similar design to V-22 Osprey with blades in wing tips .. cool
and it loks so cool! would it be quieter? i’d assume so
Appropriate as an emergency aircraft. Would require less space to land and take off and reach difficult to access regions.
I’m afraid it will not work ‘without wasting fuel’ .
The efficiency of a rotorcraft depends critically on its ‘disc loading’ that is the amount of weight carried per unit area swept by the rotors. For a given weight lifted, making the rotors half the diameter means forcing the air downward at four times the speed, which in turn means using sixteen times as much power. That’s why helicopters have huge rotors, instead of small counter-rotating fans: they’re inefficient enough as it is, without geometrically increasing the fuel used per tonne-km transported. Sorry: won’t work, at all, and for fundamental reasons, not incidental ones.
It IS very similar to the V-22 Osprey….which was a big bag of fail…cool idea…it’s just a lot of pressure where the center pivot stems out
There’s designing…and then there’s engineering.
Learn the difference. Choose one.
Yes. There’s fantasy and there’s….reality.
I think they tried something similar on Myth Busters and it was busted? But if it did really work I would love to test one out. I know I could never own one, they would be far to expensive for my budget.
Whoaaaaaa!!!! What a nice heli… This looks like a helicopter in the future!
