The unique Russian demonstrator of high-speed helicopter continues flight trials, reported by Magazine “Helicopter Industry“.

The technology demonstrator of new high-speed helicopter was spotted during the flight test on Mil Moscow Helicopter Plant, Defence-blog.com reported.

The technology demonstrator is based on the Mil Mi-24K military helicopter. Several fuselage parts have been redesigned to decrease aerodynamic resistance and improve the helicopter’s high-speed performance.

The demonstrator will be used to research technologies for increasing the rotorcraft’s flight speed to 400 km/h and, later on, to over 450 km/h.

The results of the demonstrator testing and the technology developed within its framework may be used for other helicopter programs, particularly, the new Mil Mi-38 heavy and some combat aircraft.
