Mi-26 helicopter upgrades for Defense Ministry
Holding “Helicopters of Russia” prepared a project for the modernization of the Mi-26 helicopter for Russian military aircraft. At present, the Rostvertol plant is already working on the creation of a prototype of the new Mi-26T2V with the subsequent implementation of a complex of flight tests.
As the general director of the holding “Russian Helicopters” Andrey Boginsky said, the machine will embody the latest technical solutions taking into account the use in combat operations. “I want to note that we are talking about the modernization of the military version of the Mi-26 rather than the Mi-26T2 helicopter, which is exported,” he said.
The modernized Mi-26T2V is a heavy wide-body transport helicopter with a carrying capacity of 20 tons. The number of crew members of the updated version remained the same – 5 people.
The new machine will be able to provide flights in the conditions of any region, including, with complex physico-geographical and unfavorable climatic conditions. Also, the helicopter will be able to be operated in conditions of unequipped trails and along routes outside the trails, over unoriented terrain, in conditions of fire and information counteraction of the enemy.
The machine is equipped with a modern integrated complex of on-board radio electronic equipment NPK90-2, which provides helicopter piloting day and night with automatic flight along the route, exit to a predetermined point and approach, as well as pre-landing maneuvering and return to the main or alternate aerodrome. The air defense system of the helicopter provides helicopter protection against missile damage with radio and opto-electronic guidance. Source rostec.ru DD 20 OCTOBER 2017
