Helicopter Three-eight to replace the Eight

Helicopter "Three-eight" to replace the "Eight"

The development of helicopters, observed in recent years, to the middle of this decade should bring this branch on the second-largest in the world arms exports, according to the Center for Analysis of World Trade instrument. With all of this in the middle of more helicopters bought and sold, as well as at the moment, will not be fighting, but multi-purpose machine. But such industries will rise only to the 2014-15 year. And it is already preparing vertoletostroiteli around the world. The reason is clear: you can not give the market a machine that meets its requirements — will lose their share in it.

That's the Russian holding company "Helicopters of Russia" does not want to, at least, to lose ground. So, at last in the month of August the MAKS-2011 was presented at once a few helicopters. This E-26T2 refreshed with electronic equipment, the Mi-34S1, recently committed its own first flight and promising project of Mi-171A2.

Apart from these helicopters was once again presented and ace Mi-38 standard. This helicopter yet pass the tests, but it is expected that in 2014 it will go to the series. It will be performed in Kazan. By the end of this year, maybe, will be signed the first contracts for the supply of the latest machines.
Today's test is limited to 2-machines — OP-1 (first flight in 2003) and OP-2 (first flight in 2010). At first, they were equipped with 2 turboshaft engines Pratt & Whitney PW 127/5 the highest power up to 2500 hp At the beginning, when the development of the helicopter had just started (late 80-ies of the last century), it was planned to put him on the engines of "Klimov" TV7-117V (power up to 2350 hp). But the situation is languid 90 foiled those plans. Klimovskikh engines were brought to the state of the applicable flight test, relatively recently. To this day, MVZ. Mile received a total of 6 Russian engines. So, most likely, a series of helicopter go to the "Pratt-and-Whitney."
All the same, the beginning of the supply TV7-117V will allow obkatat and Russian engines — will set them on the first ace instance.

Both experienced and all serial helicopter engines are installed behind the main gearbox. It was made to reduce the noise in the cabin, and to increase the safety of the crew and passengers in the event of an emergency landing. Another "nuance" to reduce the negative effects of emergency landings — energy absorbing landing gear. Like the Mi-8, it is made non-retractable.

Where are the huge differences in helicopters are the most experienced in the equipment. OP-2, in accordance with the current trends in the development of aircraft, avionics received IBKO-38 (developed in "Transas"). This complex is created in accordance with the concept of "glass cockpit." Representatives of the "Transas" and MVZ. Mile say IBKO-38 allows you to not only remove the crew of a flight engineer, and even seriously reduce the duties of the second pilot. In the case of the passenger version of the helicopter, the second pilot can even be not so much a pilot as a steward. Also, the designers have not forgotten to equip the Mi-38 control system serviceability of on-board equipment. This system, together with a number of other "small" innovation, according to the developer, reduces labor-intensive maintenance of the helicopter. Compared with E-8, Mi-38 asks almost half the effort for the work.

The design of the Mi-38 as the most experienced and future production, mixed: power elements of iron, and are widely used in the casing of composites. Propeller blades, as well as on some previous Mil helicopters, fiberglass, made by continuous winding technology. Rotor with 6 blades, managing — four. With all of this last is the X-shaped structure as a combat helicopter Mi-28. All blades are equipped with electronic anti-icing system and sensor damage.

Mi-38 helicopter multi-purpose. For this reason, initially developed various options for assembling the cargo compartment. Perhaps equipment of the helicopter as a cargo or passenger. If you choose the second option, the cabin can accommodate up to 32 passengers with luggage. In the case of equipment of the helicopter in VIP-version, of course, seats will be less. In the ambulance version E-38 can carry up to 16 the wounded on stretchers, accompanied by 2-3 doctors. Cargo version of the helicopter, with the highest take-off weight (15,600 kg) can carry in the cargo up to 6 tons of cargo. On the outer suspension Mi-38 picks up on a ton more.

Flight data for helicopter engines with PW 127/5 of the following: the maximum speed — 320 km / h, cruising — 285. Range of up to 1300 km, and a service ceiling of a little more than 5 km. With all of this in nedavneshnem (early October) test flight of the Mi-38 headed for the height of 8000 meters, which is a huge achievement for helicopters in general. Senior test pilot MVZ. Mile Klimov claims that the helicopter at an appropriate dynamic load can reach the ceiling, and 9 km.

Currently under way to improve the work already achieved traits. Namely, planned to see the greatest weight in almost a ton due to the payload. Also, a number of possible customers lust build on the new helicopter wider side door. This is also the wish will soon be taken into account. Most likely, all of the innovations will be combined on a fourth of the prototype, which will be built in the coming year. And at this point finish construction of the third helicopter. The clear structure of the equipment OP-3 and OP-4 has not been disclosed, but one can imagine that at least a fourth car will be Russian engines.

It is expected that the new helicopter will buy those countries that already have experience in the use of the Mi-8, also Mi-38 has with him a number of general aspects of the use and maintenance. This "continuity" can provide the Mi-38 has excellent prospects — "Eight" is currently flying more than fifty countries of the world.
