The Russian Helicopters holding (part of the Rostec State Corporation), within the framework of the MAKS-2021 International Aviation and Space Salon, for the first time presented a sample of the latest modification of the Ka-226T light helicopter manufactured at the Ulan-Ude Aviation Plant.
A prototype of the helicopter was presented at the airshow, which will begin a series of test flights in the fall. One of the key features of the upgraded Ka-226T helicopter is its ideal adaptability for high altitude flights; the modernization project received the working title “Alpinist”. The machine has a coaxial rotor design, which provides good controllability at the most extreme altitudes in low air conditions, resistance to strong crosswinds, high climb rate, the ability to take off and land on sites located at high altitudes. Also, the Ka-226T helicopter is highly effective when flying over water surfaces. It can take off and land on the deck of even small sea vessels.
The machine is distinguished by a low vibration level, ease and simplicity of control, the ability to take off and land on sites of minimal dimensions (including in urban infrastructure), high hovering accuracy even when working with a load on an external sling, safety of passengers landing when the propellers are working.
The upgraded Ka-226T differs significantly from the previous models of the Ka-226 family. The helicopter has a new airframe design with significantly improved aerodynamics. The fuselage is made using modern lightweight materials, the control system and the electric system of the helicopter have been modernized, a shock-resistant accident-resistant fuel system has been installed that meets increased safety requirements. At the same time, the volume of fuel tanks was increased with the provision of centralized refueling. The helicopter is also equipped with a new complex of flight-navigation and radio communication equipment.
Compared to previous models, the updated Ka-226T will have improved flight performance. In particular, the flight speed will be increased, the weight of the empty helicopter will be reduced, the range of use will be increased, the machine will be able to be used at altitudes up to 6500 meters. The helicopter can optionally be equipped with oxygen equipment, ballonets, air conditioning and heating systems, certification for passenger transportation is planned.
Serial production of the Ka-226T “Climber” helicopter is planned to begin in 2022 at the Ulan-Ude Aviation Plant in close cooperation with the Kumertau Aviation Production Enterprise.
