加力14.5吨和117C一样,不过静推力多少没说,3000小时的寿命比117C短?莫非117C有4000了

目前生产的117S达不到,可能也就2kh,几年后方有可能,分阶段逐步实现嘛

有这种可能,新机制造117会有统一的可能。

如果升级的话萨留特还有机会。毕竟修改量最小。

美国的F119、F135的涡轮前温度也没有超过2000K,俄罗斯以前的发动机就更低了,这一下子就跨到2100K,我认为 ...

同意你的看法,毛子的在基础预研方面比老美差多了,我很怀疑2100K是否真实。

At the Twelfth International Exhibition "Engines-2012" held a press conference the President of the Board of Directors of JSC Zaporozhye "Motor Sich" Vyacheslav Boguslayev. "AviaPort" gives basic information on voiced at a press conference.



About



At the very outset V.Boguslaev focused on general issues relating to the exhibition and the situation in the aircraft engine in Russia and Ukraine.



Concerning the evaluation of the exhibition, V.Boguslaev said he expected more from her. The main interest in the exhibition were new Russian materials and manufacturing technology of these components of aircraft engines and aircraft.



JSC "Motor Sich" in 2011-2012.



The head of JSC "Motor Sich" stopped briefly on the outcome of last year and some plans to work in the current year. "Motor Sich" continues to work on the airplane, helicopter and ground-based gas turbine engines and industrial installations. In 2012, the company plans to reach the level of turnover in the $ 800-820 million net profit for 2011 the company divided, its volume is allowed up to five times to increase dividends, despite the fact that large sums of money being spent on modernization. Today, the company "Motor Sich" when it comes to big, completed modernization. In the next two to three years, efforts will focus on re-procurement framework, metallurgy, instrumentation and machinery production. In this machine tool industry in our country is completely destroyed, and you need to buy a license, or combined to make five-coordinate and seven-coordinate machines. And for the machines immediately raises the question of tool production - always in the Soviet Union, Russia and Ukraine, the company made an instrument for themselves. But not today. For the manufacture of tungsten carbide tools are needed powders and coatings, but their production is discontinued.



At present JSC "Motor Sich" pays great attention to the niche of the aircraft and helicopters, which are not produced in Russia. This is a small 4-6-seaters. The company now operates in conjunction with the Austrians in this direction in order to put them in Kiev developed the engine. Helicopters with a takeoff weight of 5.7 tons are also very popular in the aviation market. The general trend in Europe - medium helicopter for the armed forces and the civilian sector.



The activities of the KLA



V.Boguslaev believes that there is a need to turn to the general public with the fact that "further in the direction in which we move, we can not move - despite upbeat reports on the civil aircraft actually falls." In 2011 in the civil sector in Russia have been purchased only 10 Russian-made helicopters. In the manufacture of airplanes and helicopters, the military component is prevalent and it creates the illusion of a positive development in the country air.



The chapter "Motor Sich" gave disparaging assessment of the management of JSC "United Aircraft Corporation" (UAC). In this evaluation was to determine the most polite KLA policy as "illiterate."



KLA "burying" plans to release the An-148



In confirmation of the characteristics of the KLA, V.Boguslaev brought the situation related with production in the Russian AN-148, which is charged with production of JSC "Voronezh Aircraft Manufacturing Company" (VASO) and which, according to the recent decision, as defined by the head of production and medium military transport aircraft An-70.



Today, VASO is responsible for aircraft production series Il-96-300/-400T and An-148 aircraft, and today VASO can not cope with the production of AN-148. Placed on the VASO production of An-70 - means the program known to bury the An-148, believes V.Boguslaev.



According to him, the VACO has been reduced headcount by about 1,000 people, and all the company left about 7,000 people. In order to comply with all program production aircraft An-148, IL-96 and AN-70, an estimated head of JSC "Motor Sich", one must gain an additional 6,000-7,000 workers.



In the former KLA leadership was the view of making the An-70 at the Ulyanovsk "Aviastar-SP" having idle capacity, the reserve production capacity. It was also the opinion of the advisability of placing production at JSC "Kazan Aviation Production Association. Gorbunova" (CAPO), this solution would also be useful as specialized CAPO earlier and now specializes in the production of large military aircraft, which created a huge industrial buildings , set the appropriate required crane girders, etc. Moreover, it has been handling the leadership of Tatarstan in the Russian leadership to the An-70 is completely done by CAPO. "However, the springs that exist today, direct solution of this problem in a completely different direction," - with great regret V.Boguslaev.



According to him, "eventually we will witness a transformation in the leadership of the KLA", but again we lose time, which is already lost a lot - for 20 years, An-70 is not done. During this time in Europe, "up to one centimeter," the plane made a similar purpose A400M, except for the engine for it, so the A400M does not have the same characteristics as the An-70, for example, raises at least 10 tons of cargo.



Next stop on the program V.Boguslaev Tu-334. "And in Russia, Ukraine and weakened discipline. There are two Resolutions of the Government on the formulation of the production of regional and short-range, certified aircraft Tu-334. However, UAC decides not to make this plane. Government says to do, and officials at some level decide not to do , "- he said. Answer the questions: "The production of this aircraft is not provided with a" product line "," ruler "and so the KLA." This is a response to the government's decision. Why not ask for inaction?



Program issue of AN-148



V.Boguslaev in speech and in answers to the questions described the current situation with the production and release of AN-148 in Russia and Ukraine. AN-148, the most in demand in the operating conditions in the countries of the CIS countries "third world" was mastered the production of two aircraft plants - an aircraft factory in the Ukraine "Aviant" (now a pilot plant, "Antonov") and the Russian VACO. Both the plant are involved in cooperative supply program production of AN-148.



Aircraft factory "Antonov" recent well-equipped, conducted a technical re-equipment by purchasing the most modern equipment, do not tear the delivery schedule in Voronezh.



For such an aircraft factory, as VACO, is quite capable of production would have been 20-25 An-148 aircraft a year, it's not a problem for VACO. However, to date production plans VACO provides delivery of only seven An-148 aircraft in 2012, in 2013, too, 7, and in 2014 - only six, and then this year's edition is now viewed poorly. Moreover, currently in Kiev are two ready-made 100-seat aircraft An-158, but this car is not allowed either to produce in Russia, or to sell in Russia.



"I also told the Director of airlines that have a desire to take the An-158, and then come to certain people and say that in this case is not a bank loan, there will be preferences, etc.," - said V.Boguslaev.



It is known that before the fault of the pilots crashed AN-148, intended for delivery to Myanmar (Burma), was an order for two aircraft. The Russian authorities have proposed to put the customer instead of the An-148 - two Superjet-100. "We arrived in Myanmar on the Russians, about the nasty things uttered by the An-148 and proposed Superjet-100" - commented V.Boguslaev.



Meanwhile, the first results of the exploited, however, still a few An-148 aircraft are very positive. For the class of aircraft An-148 flying 330 hours a month - a record duration is about 4000 hours per year, and the rate of annual flying aircraft on the original Terms of Reference for the establishment of An-148, taking into account the price of jet fuel at the time, was estimated at 2500 hours a year. Now sometimes there is talk about the road system maintenance, etc., but it improved during the operation and the wider operation, the faster will be done away with the inevitable "teething problems" of the aircraft. Zaporozhye experts have created two "kits" in Moscow to Voronezh operator in St. Petersburg. This provides a high level of monthly deposit. The very design of the engine allows, thanks to modular design, engine repair "on the wing."

Modernization and repair of engines D-18



V.Boguslaev said that now the new text has been prepared intergovernmental agreement (MEA) between Russia and Ukraine to resume production of the modernized An-124. And earlier MEAs were, but they are allowed to maintain the airworthiness of the An-124. Today, at the "top" of Russia and Ukraine have agreed to restore the production of AN-124 in Ulyanovsk.



The four companies: Group of companies "Volga-Dnepr", JSC "Motor Sich" SOE "Zaporozhye Machine-Building Design Bureau" Progress "to them. Academician AG Ivchenko," state enterprise "Antonov", signed a joint program, the implementation of which should be put $ 62 million to make a new profile of the D-18T. He will be improved for noise, emission of harmful substances into the atmosphere. Thanks to the upgraded engine, the aircraft AN-124 resumed production at 150 tons carrying capacity will increase with the load range of 4,600 km to 6,500 km. But the question that the plane was flying at 6500 km is not, and at 10000-11000 km. Therefore, meetings are held on the issue of finding and opening a research and development on a much more powerful D-18 ser.5, which will increase the range.



Sam modernized aircraft completely redesigned "the number". Crew - two or three people. The D-18 will have an electronic control system, as the engine itself redeveloped "by number". Digital autopilot does Ufa FSUE "UNPP" Lightning, "and in the late summer of this year, it should be shipped in Kiev equipment.



For a long time did not address the question of repair of aircraft engines D-18 not only on aircraft operated by airlines, but also and above all for military transport aircraft An-124 Russian air force. First of all, the military demanded Russia to repair a D-18 was produced in Russia. JSC "Motor Sich" eagerly responded to the proposal. Currently, aircraft repair factory № 121 in Moscow Region Kubinka acts of the Russian-Ukrainian joint venture (JV) to repair D-18. In 2011, the Kubinka were repaired first four engines D-18, this year will be repaired 6 or 7, D-18. A contract was signed. It will be small and medium repairs. Overhaul D-18 in Kubinka to do is impossible, since there are no test facilities. To make the test facility must sign a Terms of Reference - otherwise the Moscow "Giproaviaprom" does not accept an order for the design. Today, the price is determined, and such TK 2012 must be released. This test stand in Kubinka have to do with the prospect of a D-18 engine thrust ser.5 30 tons and have almost double the capacity of the test box. The Minister of Defence signed everything there is to be built a test stand in Kubinka.



Prepares production of engines D-27



The head of JSC "Motor Sich" recalled that the Russian Air Force decided to buy the medium military transport aircraft An-70 four-engine D-27 passing phase of flight testing. He further elaborated on some points of organization of production of D-27.



Today, we are talking about a possible joint venture to organize the production of D-27 with the participation of Russian companies, but no one bothers to work within the intergovernmental agreement signed earlier.



V.Boguslaev said that he was personally opposed to any kind of "add-ins" - the joint venture would talk about intellectual property, who are more invested. Cossacks on the engine D-436 "butt" for 15 years, and the engine is already flying, and did not realize who the property belongs. Producers - it is not necessary, and on top of raising these questions. Everything was done in the USSR. We work with the Moscow plant "Salut" voluntarily, the quality of work on the "Salute" has been brought to a high level. All we have so far obtained. Already, the engine D-27 is produced in conjunction with the "Salute", which performs about 35-40%% of the work.



The D-27 will also be equipped with electronic control development of the Russian Federal State Unitary Enterprise "UNPP" Lightning "." This is an extremely complex system, many functions lay the military, the motor with double rotor, it is very difficult work, "- said V.Boguslaev.



One AN-70 Russian bought, signed a contract in the first quarter of 2013 the aircraft should be placed Defence Ministry. In the An-70 is already being trained Russian pilots in the company - developer of the aircraft.



As reported, for the period until 2020 is planned to build about 320 engines D-27.



AN-178 will be equipped with traction motors 8,2-8,3 tons



Developed in Kiev at the State Enterprise "Antonov" medium military transport aircraft An-178 carrying capacity of 18-20 tons of engines will be equipped with high take-off thrust. Currently under construction, the first prototype An-178, and in 2013 he will be demonstrated. This year, the stacks under the plane to "Antonov" ready. The wing remains the same as in the aircraft An-148 engines will be more powerful. Who are the next in a series of engine thrust 8,2-8,3 m, taking into account peculiarities of operation of transport aircraft. This aircraft is not only interested in the military in Russia and Ukraine, but show interest in India and China. There is an attempt to join forces with Embraer, they are also trying to build such an airplane, but do not have the experience and appealed to the State Enterprise "Antonov".

Samara aircraft factory ready to produce the An-140



The head of JSC "Motor Sich" separately focused on the production of AN-140 with TV3-117VMA-SBM1. Samara aircraft factory "Aviakor" very seriously prepared for the production of AN-140, the plant technically and technologically equipped, typed workers and professionals, has a good staff and is ready to test now produce up to 20 aircraft An-140 in a year. In terms of the 2012 delivery of six aircraft, the plant said that in any case guaranteed to assemble four planes.



The Russian Air Force ordered 10 aircraft An-140 and received today has two cars, they are already in Zhukovsky, and to maintain the airworthiness of the Cossacks created for them "first-aid kit." On the possible repair of the engine can be said that the repair will do the repair plant in Gatchina, and gear - factory in Aramil. Cossacks have agreed on the points of repair, which will be done in Russia.



According to, V.Boguslaeva in Yakutia 4 AN-140, two of which are leased and two owned by the airline. Their aircraft operator support, parts are removed from the lease, and fly their own planes in full. Plaque about 300 hours a month on a small plane, flying in the winter. Fly on the routes Yakutia - Khabarovsk, Vladivostok, China.



Leasing in Russia, China and Brazil



Chairman of the Board of Directors of JSC "Motor Sich" believes that the leasing scheme in Russia is dying. In Russia, two leasing companies, one of them, unfortunately, is "a prosecutor", the second - IFC - switched to the transfer of leased aircraft company Bombardier, and instead of the An-148 in Russia, including state money, will sell foreign aircraft.



The most advanced leasing schemes, and they are all over the world is very different, are China and Brazil. In China, interest rates dampens the Export-Import Bank of China, and the main "body" of the credit given for 12 years. In Brazil, the two state banks. One of these funds that are exported, and other loans to those countries that buy Brazilian products, with little or no interest. In Russia and Ukraine a loan offer for 10 years, and in Ukraine, plus 18 percent of bank credit, plus 20 percent for the leasing company, for a total need to pay a premium of almost 40%.



Helicopter engine TV3-117VMA-SBM1V



V.Boguslaev also spoke on the work program to promote helicopter engine TV3-117VMA-SBM1V. The engine has successfully passed state tests in Ukrainian helicopter MI-8, showing the phenomenal rate of climb, to operate at high temperatures and in emergency situations. The engine also successfully passed the state test bench in Russia-based aircraft repair plant in Gatchina. To conduct public flight testing in the Russian Defense Ministry has allocated one helicopter Mi-8MTV. Zaporozhye has put two engines to be installed on the helicopter, but it is a serious slowdown. While all the graphics engine to replace the helicopter and began to break down state tests.



JSC "Motor Sich" is also set two TV3-117VMA-SBM1V in America, two in China, is preparing to send to Belarus.



All interested in this engine along military lines. In the civilian sector for this engine, almost a fifth-generation, there is no interest for unknown reasons.



To the engine develops. For example, set up TV3-117VMA SBM1V-4E with electric, and the developer proposes to change the old engines TV2-117 helicopters Mi-8. In Russia such helicopters flying around 1000, and around the world - up to 10,000 Mi-8/17. At present JSC "Motor Sich" is already entered into contracts for the supply of helicopters to remotorizatsii Mi-8/17 abroad. One can only hope that in Russia, the operators of the Far North, Far East, will knock the existing bureaucratic barriers.



The peculiarity of the TV3-117VMA-SBM1V are increased up to 2500-2800 hp (TV3-117VMA - 2200 hp) power, ability to operate in mountainous areas and in hot and humid climate.



In the year 2012 must be made 64 AI-222-25



According V.Boguslaeva in the current year is planned to produce 64 engine AI-222-25 Russian combat trainer aircraft Yak-130. In 2011 it produced 40 engines such as AI-222. Moscow Plant "Salut" is a "finisher" in the release of AI-222-25 in Russia, he assembles engines of the sets coming from the JSC "Motor Sich", produced independently of the details, is the final assembly and test engines before shipping.



V.Boguslaev signed an additional schedule for delivery of modules (sets of parts and components) as "Salute." Now the Russians want to make a new version of the Yak-130 and require a more powerful engine.



Repair of AI-222 engines to Russia for the Yak-130 will carry Eisk.



MS-500B engines and AI-450



V.Boguslaev regretted that nothing has been done in terms of performance recorded in the Russian program to create a helicopter weighing 5-6 tons, while in the program and the type of helicopter. JSC "Motor Sich" under this program will drive the MC-500V, just a great engine. This year, we must try to certify it. But the movement to establish a civilian version of the helicopter does not. At the present time in Russia built two plants - to build helicopters, AgustaWestland and Eurocopter. This is done in an environment where there is a project in Russia Mi-54, is the engine for him.



JSC "Motor Sich" is also working with "Rostvertol" the modernization of the Mi-2 Mi-2M with the installation of its two engines of AI-450. May 17 will raise the Mi-2M in Rostov. Engines have a couple of them were racing, flying was not. In this class, 3.5 tons of helicopters do not. Every year in Russia repaired 25-30 Mi-2 at three plants, but in the old profile, but it has weak engine (GTD-350). We are under orders of MVZ. Mile made the AI-450 for the modernization of the Mi-2M.



Engine modifications - AI-AI-450M and 450M1 c power at takeoff 400 or 465 hp (Depending on the setting of ACS) is designed for remotorizatsii previously issued by the Mi-2, where they replace the engine GTD-350.



The D-136-2 Mi-26T2



The head of JSC "Motor Sich" is a bit touched, and the upgraded engines for heavy transport helicopter Mi-26T2. It is expected that the new version of the helicopter will be equipped with more powerful and more refined engine D-136-2. To date, D-136-2 was developed, tested on ground stands, but lags behind the system of electronic engine management.



It should be borne in mind the economic component of the project - the need for the Mi-26T2 and engines D-136-2 is relatively low. You can submit a release in the order of 8-10 year engines. Produce D-136-2 is planned for the JSC "Motor Sich", and will be repaired in Russia - Aramilev.



The new theater will find the MS-14 demand for air travel market



V.Boguslaev stressed that the idea of ​​excellence remotorizatsii biplane An-2 for many years. Create a second such aircraft while no one has for a long time and will not succeed.



In Russia, Omsk by "Flight" has produced 26 under the designation modernized biplane An-3T with the TVD-20 engines, which are also produced in Omsk. Limited edition (remotorizatsii) An-3T is due to a very high price remotorizatsii - about $ 2 million in aircraft An-3T only the cost of equipment, cables, connectors and sensors costs $ 850 thousand, excluding the cost of the work and the engine, so the price of $ 2 million - the "right" price for the An-3 in Omsk.



Designed by JSC "Motor Sich" theater MC-14 is designed to remotorizatsii An-2 aircraft. By creating a MS-14, provides an opportunity remotorizatsii An-2 with this engine for more than half the price - the price reduced to $ 850-870 thousand This aircraft will be cheap and affordable.



At present the work to create the MS-14. It can be put on the An-2 aircraft repair any enterprise in any country - to buy a license and install the MS-14 Antonov An-2. At present, the two aircraft repair companies in Russia have already received concrete proposals. JSC "Motor Sich" to supply the whole package - the engine and frame.



At the present time in the world fly thousands of aircraft An-2, and the demand for their remotorizatsiyu huge, especially in countries such as China, Azerbaijan, Kazakhstan.



Joint venture of four ARZ



V.Boguslaev really appreciated the ongoing work to create a joint venture for the repair of engines, manufactured by JSC "Motor Sich". This year all the plants around 2000 Russia will repair engines, about half - the engines of JSC "Motor Sich". The newly created joint venture "Aviaremont-MS," which provides a good half of the repair of engines due to the fact that the four aircraft repair plant was transferred to Repair Technology, JSC "Motor Sich" has helped to repair industrial equipment, has helped and continues to build on the two test plants boxes, and supplies spare parts, without intermediaries - this is part of JSC "Motor Sich" in the works with the Russian Defense Ministry, which is extremely competent work in terms of repair. Previously, all orders for the annual repairs were - the engine did in June, and late in the year it was necessary to close all the work, and repairers in a hurry, could be wrong. At JSC "Motor Sich" today signed a rolling contract for three years, with possibility to prolong it for another three years. And the price increases transparency - by 3.5% per year. We work with four aircraft repair plant - Eisk, Aramil, Cuban, and Gatchina. Now we are preparing a government decree on the assembly work on the aircraft AN-74 aircraft repair plant in Ivanovo, where repair is now the An-72 and AN-74.
