The „Hummel“ („bumble bee“) is a light helicopter-concept 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.
To be moved easily at the ground the „Hummel“ has wheels at its forelegs and can be folded flat.
Because of that it doesen‘t depend on mobile heliports and can safetily be stored. These advantages are shown especially when there is minimal space, like for example on research ships.
