Russian Helicopters presented a draft proposal to develop a unmanned tiltrotor aircraft during MAKS-2015 airshow in Moscow. The aim of the project is to create a family of high-speed multi-purpose rotary-wing aircraft.
The main objective of the project at this stage is to identify the critical technologies and systems necessary to further the creation of a whole family of manned and unmanned konvertoplanov (tiltrotor) aircraft with different maximum take-off weight.
Tiltrotor provide the ability to perform vertical takeoff and landing from small strips and carry more passengers or goods at a higher speed and to greater distance than conventional helicopters.
Tiltrotor aircraft can take off and land vertically like a helicopter, and cruise like a turboprop aircraft by rotating its engines 90 degree to horizontal position.
Current tiltrotor designs in the world include the AgustaWestland AW609 commercial tiltrotor and the Bell Boeing V-22 Osprey military aircraft operated by U.S. military.
