The Ansat multipurpose helicopter equipped with an internal fuel tank and ballonets is presented at the international exhibition HeliRussia-2020. It is planned to submit the prototype of the new generation of the Ansat helicopter for testing by the end of the year, said the press service of Russian Helicopters Holding.
“By the end of the year, we plan to transfer a new-generation Ansat prototype for testing. In addition to a wide range of optional equipment, this helicopter will receive an upgraded fuel system with increased capacity, the latest avionics for instrument flights, as well as a lightweight fuselage with expanded use of composite materials,” said the Director General of Russian Helicopters Andrey Boginsky.
The Ansat emergency splashdown system is designed to keep the helicopter afloat in the event of an emergency landing on water. Ballonets provide buoyancy of the helicopter for 30 minutes. The kit includes inflatable ballonets, two life rafts and an emergency life support kit (including a radio beacon for locating the aircraft by rescuers). Equipping this system will allow Ansat to fly to oil companies' facilities located at a considerable distance from the coast and participate in search and rescue operations over the water surface. The Federal Air Transport Agency certified the installation of an emergency splashdown system on the Ansat helicopter in 2020 reports Zvezda.
An additional fuel tank is designed to increase the ferry range of the helicopter. This option will be in demand when making long-distance flights, for example, when you need to deliver a helicopter to its permanent base. An additional 192-liter fuel tank makes it possible to increase the Ansat's flight range by 140-150 km - up to 650 km.
Moreover, starting 2021, customers will have access to the Ansat modification with enlarged main fuel tanks. The volume of the main fuel system will be increased by 20%, which will increase the flight range by 135 km. Thus, when using an additional fuel tank on the upgraded Ansat, the maximum flight range will exceed 750 km.
In the future, it is also planned to equip Ansat with a winch and an external sling, which this year are being tested at the flight test complex of the Kazan Helicopter Plant. The winch increases the efficiency of the helicopter in search and rescue operations and allows for hovering loading and unloading operations. The device provides lifting and lowering of people and goods with a total weight of up to 272 kg.
The external sling is designed to carry cargo weighing up to 1,000 kg, while the maximum take-off weight of the Ansat with an external sling will be increased to 3,900 kg. The suspension also includes a weighing device and a load release system.
The multi-purpose light helicopter Ansat is built to a classic single-rotor design with a four blade main rotor and a two-blade tail rotor. The Ansat was developed in line with the latest AP-29 (FAR-29) Category A regulations, and meets high safety standards. The Ansat comes in different models, one with the latest fly-by-wire flight control system and the other with the traditional hydro mechanical control system, with the latter certified by the Interstate Aviation Committee’s Aviation Register (AR, IAC).
