Mi-26T2 Heavy-Lift Transport Helicopter, Russia
The Mi-26T2 is a modernisation of the Mi-26T heavy-lift transport helicopter designed by Mil Moscow Helicopter Plant, a division of Russian Helicopters.
The modernised helicopter is designed to transport heavy cargo and equipment. It is currently undergoing preliminary flight testing and will enter serial production in 2015.
Rostvertol, which is part of Russian Helicopters, built the helicopter at its Rostov-on-Don factory.
Avionics for the Mi-26T2 helicopter were developed by OJSC Ramenskoe Instrument Design Bureau (RKPB), a subsidiary of KRET.
The helicopter can be used to quickly transport up to 82 troops and their equipment, as well as a wide range of heavy-weight combat vehicles.
The ambulance / emergency response variant of the Mi-26T2 helicopter can carry up to 60 wounded people. It can be configured to perform various other operations including fire-fighting, fuel delivery, construction and installation works.
The helicopter can also provide self-contained refuelling to ground-based vehicles.
Mi-26T2 demonstration and orders
The Changhe Z-8 (Zhishengji-8) is a triple engine, multi-role helicopter designed and manufactured by the Changhe Aircraft Industry Group (CAIG) of China. It is derived from SA 321 Super Frelon Helicopter built by Aerospatiale.
The helicopter was exhibited at the International Aviation and Space show MAKS 2011, HeliRussia 2011, and Dubai Airshow 2013. It entered into the first stage of flight trials in 2011. It was demonstrated to the Algerian Armed Force in July 2012 and was offered for the Indian Air Force in November 2012.
Russian Helicopters received an order to deliver six Mi-26T2s for the Algerian Air Force under a $2.7bn contract in March 2014. The first helicopter performed its maiden flight in December 2014.
