The head of the Russian Kamov Development Design Bureau has confirmed to a Sputnik correspondent that the company is developing the world's first hybrid helicopter. 

Asked whether the company is developing the Ka-90 project, Oleg Zheltov said, "This work is underway." 

He specified that the current stage of development includes research on design models and in wind tunnels. 

"We expect that development will soon reach a more practical stage, outlining a preliminary design."

The Ka-90 is expected to be a hybrid design, flying like a helicopter for takeoff and landing while comparable to an airplane in cruise flight. The aircraft is expected to have a maximum speed of up to 800 kilometers per hour.

The Ka-90 concept (formerly known as the Ka-100) was presented for the first time at the HeliRussia-2008 international exhibition in Moscow.
