Helicopters, when compared to the likes of airplanes, are relatively new to the aircraft world. They only came into production and daily use following World War 2, and by then numerous engineers and designers had already begun to design their own versions to outperform and outproduce the competition. Everyone the military and elite businessmen of the world wanted to get their hands on a brand new helicopter. Some models were incredibly unique, and some were simply wild. Here are ten of the coolest experimental helicopter designs ever created.

Sikorsky X-Wing

The Sikorsky X-Wing was created by the famous manufacturer Sikorsky, who offered the closest thing to an X-Wing Fighter from Star Wars we’ve ever seen. Designed sometime in the 70s, the X-Wing helicopter combines leading airframe design with aerodynamics.

Percival P.74

The Percival P.74 is rather ugly, but German engineers came up with the design for this odd appearing helicopter not long after World War 2. The propulsion technique of tip-jet rotors was implemented to the ends of each helicopter rotor.
