The Hummel Helicopter concept by Daniel Kocyba is a lightweight machine that can carry two passengers and when required it can be folded and stashed away. This may come in handy for operations, like rescue and safety. On the other hand, there’s an added risk of tension and forces acting on those joints that make it foldable.
From The Design Blog:
“The tandem rotor design ensures an efficient aircraft performance as the main-tail rotor design, without wasting fuel. The Hummel has wheels at its forelegs and can be folded flat, so it doesn’t depend on mobile heliports and can be stored easily and safely.”
