Phoenix with the brand "Il"
At the Army-2016 forum, a permanent member of the Security Council of Russia, Sergei Ivanov, when examining the exposition of the United Aircraft Building Corporation (UAC), paid particular attention to the Il-112В aircraft. Oleg Demchenko assured Sergey Borisovich that the schedule of works on the car is fully implemented.TO REPLACE AN-26
As a result of the transformation of the Russian Armed Forces, the need for a light military transport aircraft is growing. Modernization of the An-26, armed with the Military Transport aviation in the Russian Air Force VKS, recognized as inappropriate. Therefore, another attempt is being made to implement the project of the Il-112V aircraft, which would fully comply with the requirements of the Ministry of Defense. Its production was determined by the Russian government as priority projects for the development of the domestic aviation industry.
The creation of the IL-112B began in the middle of the 1990-ies, but soon ceased due to the economic crisis. Returned to the project in 2005 year, rolling out the first sample was planned for the 2007. The project was carried out in the interests of the Ministry of Defense and was financed from the state budget. The production of flight samples, transferred to the 2010 year, did not take place. The project was stopped. As the experts explained, the aircraft had design flaws and did not meet the tactical and technical requirements for a number of basic technical characteristics. The Defense Ministry turned its attention to the Antonov An-140 company.
A few years later, the Ministry of Defense returned to the IL-112В project. At the end of December 2013, it was announced that the sum of 2014 billion rubles was planned for the state defense order for 7,9 year. to conduct development work (OCD). After their implementation, it is planned to sign a contract for the serial supply of aircraft.
In 2015, the aircraft’s technical design was defended in front of the customer, who was presented with a full-size cockpit mockup to evaluate the ergonomics of workplaces, the convenience of the location of controls and liquid-crystal displays.
The protection of the technical project has allowed to proceed to the development of working design documentation for the aircraft, as well as technological documentation and in the future to proceed with the manufacture of equipment and production of prototypes of the aircraft.
At the beginning of 2016, during the planned working visit, the Deputy Minister of Defense of Russia, Yuri Borisov, visited Voronezh Aircraft Building Company PJSC (VASO).
“United Aircraft Corporation has chosen VASO as the main manufacturer of these aircraft. We renewed the contract for their development. According to the plan from the middle of 2017, the first flight should be realized. According to the reports of the military missions, while the situation is under control, everything is going according to schedule, ”the deputy minister noted.
Six months later, a meeting was held at VASO with the participation of Yuri Borisov, during which the preparation for the production of the Il-112В light military transport aircraft was also discussed.
“We agreed that every month within the framework of our interdepartmental working group, which exists together with the Ministry of Industry and Trade, we will control this project,” said Yuri Ivanovich. He also noted that the work on the development of design and technological documentation on the Il-112В for the Ministry of Defense is being completed at Il, and the plant is already assembling the fuselage sections and manufacturing the wing.
HAVE QUESTIONS
However, there are newsthat alarm the experts. In September last year, an application was posted on the state procurement site for the implementation of a component of the design and development work on the subject “Development of a turboprop engine with a free TV7-117Т turbine and an ACS for Il-112В aircraft”, the cipher is “LVTS-TV7-117CT-Klimov”. Contract price 99,8 million rubles. In such cases, as they say, the winner is a foregone conclusion. However, two months later, the procurement commission decided to cancel the tender and not enter into an agreement with the sole executor of Klimov, explaining this by changing the terms of the procurement.
And not so long ago, the United Engine Corporation (UEC) reported that the JSC “Moscow Machine-Building Enterprise them. V.V. Chernysheva ”in a short time restored production of the TV7-117 motor-sets and the beginning of their delivery to Klimov. The plant already has experience in the production of engines of this type - it was there that prior to the start of the 2000-s, the production of the previous version of the TV7-117CM engine - TV7-117С was organized. The basic part, which produces JSC "MMP them. V.V. Chernysheva ”, is identical for all types of engines of the TV7-117 family. Similar units, for example, on 80% are applicable in the production of the TV7-117CT engine for IL-112В.
Against this background, messages on informational tapes that “Omsk Motor-Building Association named after them. P.I. Baranova "(branch of JSC" Salyut "Gas Turbine Construction Center) will produce engines for IL-112В. As reported by the. Deputy General Director - Managing Director of Salyut Sergey Lyashenko, “the motor itself will be manufactured in broad cooperation, the Omsk branch will be assigned a definite nomenclature of parts and components of this product. But Omsk will be the ultimate collector and tester. The test site will be in the Krutogorsky branch, work is being actively carried out there, and we have to finish the first stand in March next year. ” The first motor is planned to produce in August.
It would seem that there are no reasons for excitement, as the Salyut Gas Turbine Engineering and Production Center JSC and the V.V. Moscow Machine-Building Enterprise JSC. Chernysheva ”have a well-deserved authority in the field of engine-building, both in our country and abroad. In addition, it should be noted that Salyut has already invested billion rubles in the development of the Omsk production site 5.
However, the fact is that earlier the UEC positioned Klimov as an industrial site where work will be carried out from design to the leading engine manufacturer of this brand, including TV7-117СМ for Il-114, TV7-117CT for Il-112В , as well as TV7-117В for the Mi-38 helicopter. Therefore, the events that have occurred look like a change in the course of the corporation in the development of enterprises and their participation in Klimov’s engine-building programs.
Experts believe that the revision of authority may be due to the fact that Klimov OJSC has de facto failed the implementation plan of the Mi-38 project, and at present it is slowing down the stage of its implementation to civilian consumers. Potential buyers are not interested in an aircraft with engine life in 100 hours. In particular, air carriers at HeliRussia 2016 said that for a year of operation helicopters spend at least (!) A resource in the amount of 300 – 500 hours.
A similar “gift” in the IL-112В project will certainly not only adversely affect the image of Klimov OJSC, the UEC and their leadership, but may also be the last straw in the government's long-term tolerance for so-called managers. It has been a time of beautiful promises and talk that additional financing is required for the successful completion of the task. It's time to take responsibility for your words and deeds.
AND NOT ONLY ENGINE
Of course, not only engine builders have a black mark. For example, Technodinamika JSC, which is very far from the position of a reliable partner of the Ministry of Defense, participates in the aircraft creation program for a number of systems.
“Tekhnodinamika” Joint-Stock Company has not supplied three multi-position launchers for the Tu-160 aircraft. The delivery of six units of the 2015 program of the year is in jeopardy, ”said Russian Deputy Minister of Defense Yury Borisov in his report on the summer of military production in the summer of 2015.
Currently, the company seeks to create a positive image and strengthen its market position. In this regard, Tekhnodinamika cheerfully reports on any of its successful steps, including the design of IL-112B.
The holding has undertaken to provide the aircraft with an unstable frequency alternating current generation system, an unstable frequency converter with a stable transformer rectifier device. The press service of the company reported that “on the power supply system for IL-112B, the stage of technical acceptance of design documentation (working design documentation - Y.A.) was completed, work began on the technological preparation of production, designing and manufacturing of equipment and manufacturing parts and assembly units Ufa enterprises holding.
According to the chassis system for IL-112В, the stage of the RCD was successfully completed. Work is also underway on the technological preparation of production and the production of assembly units, the design and manufacture of stands for preliminary and endurance tests. By the year 2021 holding must deliver for IL-112В 34 set of bearings and cylinder chassis.
The company also participates in the development of the latest flap movement system. “The Il-112В flap transfer system is based on an electric drive,” the press service said, citing Maxim Kuzyuk, the director of Tekhnodinamika holding. - The efficiency of replacing the hydraulic drive with the electric drive is manifested in reducing the mass of the system, increasing reliability and simplifying maintenance. As part of the work on the topic, the development stage of the design documentation was carried out, technological documentation was developed, laboratory equipment was designed, the process of manufacturing the units that make up the system is underway. ”
Judging by the assurances of specialists holding, with the documentation a complete success. What will be the final result of practical manufacturing of high-quality products, we will find out next year.
Nevertheless, according to experts, in general, the IL-112В project is progressing quite successfully. In July, at the Central Aerohydrodynamic Institute. Professor N.E. Zhukovsky (TsAGI) commissioned by JSC "Il" completed the first stage of testing for a flutter of a dynamically similar model of the IL-112В aircraft. The experiment took place in a subsonic wind tunnel.
When conducting tests on a flutter, a model in scale 1 was used: 5, wing span - 5,3 m, weight - 300 kg. The data obtained indicate a sufficient speed margin to ensure the safety of the aircraft from flutter. At the same time, other parameters affecting fuel consumption, payload, structural rigidity and possible changes in the aircraft’s dynamic characteristics during flight were investigated.
Experts of TsAGI, before giving a final conclusion on the safety of the aircraft from the flutter, still have to carry out a number of studies, including the second stage of testing the model for flutter and frequency testing of the first flight model.
