The Kazan Helicopter Plant of the Russian Helicopters holding (part of the Rostec State Corporation) has completed the next stage of certification work to increase the resources of the main units of the Ansat helicopter. The achieved indicators increase the commercial attractiveness and competitiveness of the helicopter in the domestic and world markets.

Certification work included a complex of fatigue and equivalent cyclic tests of Ansat helicopter assemblies, both in the dynamic testing laboratory of the enterprise and in the industrial laboratory of KNRTU-KAI,
with the preparation of the necessary evidentiary documentation.

“The increase in the resources of the Ansat helicopter assemblies significantly affects the decrease in the cost of its flight hour. Work in this direction has been carried out systematically and in stages for several years, which undoubtedly increases the competitiveness of the Ansat helicopter,” said Nikolay Kolesov, General Director of the Russian Helicopters holding .

In accordance with the updated certificate, the assigned resource of the tail boom of the helicopter has been increased from 3000 to 4000 hours, the assigned resource of the main rotor hub assemblies is from 4000 to 5000 hours, the service life of the first overhaul of the VR-23A main gearbox and SV-23 connecting shafts is from 1750 up to 2000 hours, and their assigned resource – from 3500 to 4000 hours.

In total, 10 approvals for major changes in the standard design of the Ansat helicopter were received in 2021. The plans of the Design Bureau of the Kazan Helicopter Plant include a further gradual increase in the resources and service life of the helicopter and its assemblies, both of its own production and of purchased components. In particular, in 2022, work is planned to increase the resource of vibration dampers, skid landing gear, tail boom and a number of other units and components of the helicopter.

Ansat is a light twin-engine multipurpose helicopter, the serial production of which has been launched at the Kazan Helicopter Plant. According to the certificate, the design of the helicopter allows it to be quickly transformed into both cargo and passenger versions with the ability to carry up to 7 people. In May 2015, an addendum to the type certificate was received for the modification of a helicopter with a medical module. Ansat is certified for use in the temperature range from -45 to +50 degrees Celsius, as well as for operation in high mountains. In August 2018, based on the results of certification work, Rosaviatsia issued KHZ approval of the main change to increase the resources of a number of Ansat units and systems. In 2019, the Federal Air Transport Agency certified an increase in the fuselage resource of the Ansat light helicopter to 16,000 hp. In February 2020, the Russian aviation authorities certified the installation of an emergency splashdown system at Ansat. Also, approval was issued for a major change to increase the airworthiness limitations of a number of main helicopter assemblies, which makes the Ansat helicopter even more attractive to potential customers and increases its competitiveness in comparison with foreign helicopter technology. At the end of December 2020, the upgraded Ansat-M helicopter made its maiden flight. which makes the Ansat helicopter even more attractive to potential customers and increases its competitiveness in comparison with foreign helicopter technology. At the end of December 2020, the upgraded Ansat-M helicopter made its maiden flight. which makes the Ansat helicopter even more attractive to potential customers and increases its competitiveness in comparison with foreign helicopter technology. At the end of December 2020, the upgraded Ansat-M helicopter made its maiden flight.
