ANISOPTERA - Multipurpose Light Helicopter

_ Anisoptera is a light helicopter concept, as a modern interpretation of pioneering "soap bubble canopy" helicopters like Bell-47 or Hughes TH-55. The airframe is based on a monoblock chasis; consist of triangular lattice structure with variable profile thickness, thanks to the form flexibility of additive-manufacturing techniques. Powered by a hybrid engine set, Anisoptera is optimised for medium speed - long flight duration missions. It is also designed to offer a superior cockpit view by its bubble canopy.
_ Anisoptera is a combined Greek word (ἄνισος Anisos, "unequal" + πτερόν Pteron, "wing") which is the name of taxonomic infraorder consist of Dragonflies. 350 million years ago in Devonian peroid, dragonflies' ancestors were the first animals ever accomplish the powered flight. Despite flight dynamics are not identical, there is a strong morphological correlation why helicopters' design ends up significantly like a dragonfly.
