Description
Kazan Helicopters established its own design bureau in 1993, officially certified in January 1997, under designer Valery Dvoeglazov, to create a new helicopter named Ansat. This initiative arose from the recognized need for light helicopters in Russia following the aging of the Mi-2 fleet. Efforts to collaborate with Eurocopter on a helicopter based on the AS 350 Ecureuil were not successful. The first prototype for ground static tests was completed in 1998. The second prototype performed its first flight on August 17, 1999, powered by two Pratt & Whitney Canada PW206 engines. A subsequent prototype, featuring a longer, slimmer fuselage and PW207K engines, flew on December 27, 2001, and underwent certification from 2002. In September 2001, the Ansat-U was selected to become the new trainer for the Russian Air Force.
Design
The Kazan Ansat features a classic helicopter layout designed to accommodate a pilot and up to 10 passengers. The fuselage is equipped with a pair of doors in the pilot's cab and a pair of side doors in the transport compartment that open upwards and downwards. The design allows for the interior to be reconfigured for cargo transport, accommodating up to 1,000 kg of internal cargo or 1,300 kg on an external hook. It is powered by two PW207K turboshaft engines, each producing 630 shp, and incorporates a four-blade main rotor and a two-blade tail rotor. The VIP version includes a ventilation and air conditioning system and energy-absorbing passenger seats.
Armament
The Kazan Ansat in its baseline configuration is unarmed and carries 1,000 kg of cargo internally or 1,300 kg on an external hook. A derivative, designated the Kazan Ansat-2RC, can be equipped with a 12.7mm machine gun above the front skid support, along with four hardpoints distributed across two stub wings. This armed variant can carry a mixture of rocket launcher tubes, bombs, and anti-aircraft missiles.
Operational History
The Ansat has been deployed in various roles. The Russian Air Force adopted the Ansat-U as a trainer, with the Syzran Military Pilot Flying Training School being the primary operator. Civilian variants are used for passenger transport, emergency medical services, and cargo operations within Russia and internationally. Operators include the Ministry of Emergency Situations, Ministry of Internal Affairs, other state structures within Russia, as well as commercial operators such as Tulpar Helicopters and Russian Helicopter Systems. Orders have been placed by Eritrea for two Ansat-U helicopters and the Interior Ministry of the Serbian Republic for three for police duties. The Ansat-SK medical version has been used in EMS operations. Its operational capabilities include certification for extreme temperature conditions and high-altitude operations.
