History of Creation
Development of the helicopter "ANSAT" started in Kazan in 1994. The full-size mock-up of the new helicopter was created in 1997. With all of this it should be noted that the plans for the Kazan Helicopter Plant (KHP) to create a light helicopter, the equipped with 2 turboshaft engines, increasingly facing difficulties than show real progress. Helicopter "ANSAT" appears first independent development kazanskoskgo KB at KHP, it was created when cramped collaboration with Kazan Municipal Technical Institute. Other than that it was the first helicopter, filled-by-wire control system (EDSU). The first model of a helicopter took to the skies in 1999, and the creation of a batch machine was deployed in 2004.
With all of this development project "ANSAT" can not be called easy. On September 2012 was produced 29 helicopters: 6 prototypes, 10 civilian versions of "ANSAT" and "ANSAT-K", also 13 military training helicopter "ANSAT-U." The program of development of helicopters "ANSAT" experienced severe difficulties after one of the helicopters, which was raised in South Korea, in July 2006 was in a plane crash in which the pilot died on the machine. This has resulted in the termination of the helicopter Forest Service and the police in South Korea.
The problem that led to the crash, was assigned to the EDSU Kazan forcing engineers to conduct additional research and testing of the new system. Because of the lack of requirements for the certification of civilian helicopters EDSU Russian aviation authorities initially certified the car on the basis of time requirements. After the disaster in South Korea requirements have been supplemented and improved option the helicopter was to meet them. In March, 2010 machine got a new flight certificate, but again could not be used to transport passengers. With all this, the military, the police and the forest service could operate a helicopter, but the commercial transportation of passengers was prohibited. Reversed option helicopter was referred to as "ANSAT-K '(K — Korean).
Because of the impossibility of obtaining a certificate of compliance for passenger transport, the ready for a civilian helicopter market is not done. In order to overcome this situation LSC began working on a version of "ANSAT-1M", which was hydro-mechanical control system of exchange-by-wire system. By September 2012 in Kazan was made 2 helicopter "ANSAT-1M", which are used for ground and flight testing. By the flight test vehicle started in May 2012 year. A certificate for the model helicopter at the company expected to get to the end of 2012.
Earlier issue of helicopter time is only in the interests of the Defense Ministry. In 2011, the military has acquired 5 helicopters "ANSAT-U", 6 more were scheduled for delivery in 2012. Overall, in 2018 the state program provides for the purchase of arms 40 helicopters "ANSAT-U." Based on data from the Ministry of Defence in 2010 for each "ANSAT-U" department paid 101.4 million rubles.
Features of the design and purpose of the helicopter
In the development of the helicopter used new methods of design, which allowed to achieve an economy of not only the time of design and production tooling, and lower labor costs in other areas of production (documentation, assembly, maintenance). In order to ensure the competitiveness of the car by Performance and cost of the helicopter were balanced applied classical and modern technical solutions, technologies and construction materials. Development of "Ansat" used the concept of mass production of low prices, the greatest adaptability together with the greatest needs of the market.
Multi-purpose helicopter "ANSAT" refers to helicopters and light class has a load capacity of 1-1.3 tonnes Its maximum weight is 3.3 tons and passenger capacity of 9 people. The creation of a helicopter engaged in KB at LSC involving other companies and organizations, specializing in the production of aircraft.
Helicopter "ANSAT" is made by the control single-rotor screw, also with 2 turbine engine and chassis skid type. Helicopter fuselage of semi-monocoque construction, all-metal, but with the widespread use of composite materials. The fuselage smoothly goes into the tail wheel with a horizontal tail end washers. In the nose of the helicopter is a twin crew cabin, cargo-passenger cabin machine has the following dimensions — 1,8 x1, 3×1, 85 m, its volume is 3 cubic meters. meters. Cargo-passenger cabin is armed with a rear cargo hatches and bolshennymi side doors. Ski gear helicopter has a track 2.5 m four-bladed main rotor helicopter, its width — 11.5 m, the control screw — two-bladed, its width — 2.1 m Power plant of 2 engines available in total for the fairing gear rotor. The engines are equipped with side vozduhopoglotiteli ROM. Fuel is a 2-tanks are disposed on the edges fuselage.
Helicopter "ANSAT" regardless of the equipment may be used in the following ways:
-passenger (can carry up to 9 passengers);
-transport, including the transport of cargo on the outside of the suspension (up to 1300 kg);
-administrative (5-6 passengers);
-sanitary helicopter (2 bed-ridden patients and two medical worker);
-rescue (with special equipment);
Helicopter "ANSAT" has quite the highest flying and technical characteristics. At the highest take-off weight of 3,300 kg, it can take on board a transport version up to 1300 kg. cargo and transport it to a distance of 520 km at a cruising speed of 240 km / h Duration and range directly depend on the speed of the helicopter, height, weight and weather criterion transported aboard cargo. Service ceiling machine is 5500-6000 meters regardless of the take-off weight of the helicopter. The radius of the machine acts in emergency and rescue case, where the flight was to take place on the very probable speed of 190-210 km is equal. Ferry range empty "Ansat" is 620 km. At a distance of 100 km. the helicopter can carry a payload of 1650 kg. The introduction of additional fuel tanks can significantly increase the range and endurance of the machine.
