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.
Another odd entry is the Kellett-Hughes XH-17, which was said to be used as a flying crane for its time period. Designed in 1952, the Hughes Aircraft Company produced this first version, which was the largest helicopter in the entire world at the time.
The Sikorsky X2 was designed to combat the only problem a helicopter currently faces: speed. Helicopters tend to be rather slow, but not the X2. Sikorsky tried to experiment with multiple prototypes before coming onto this one, which used composite airframe materials for a lightweight machine.
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.
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.
Russian engineers and designed worked together to design the Kamov Ka-22, the largest and heaviest of all helicopters in the entire world. This was basically an airplane, but with rotors attached to each wing for vertical lift-off.
