The company "Sukhoi" started flight testing of a fundamentally new computing systems of the aircraft T-50. The new system is significantly more reliable and more powerful than the previous, and for the first time all design and development in the modern history of Russian military aviation did it airplane firm.The first fighter T-50 with new on-Board electronics and the microprocessor were up in the air this winter. According to Dmitry Gribov, chief designer of the company "Sukhoi" and the Director of the Directorate integration of the BWC, the latest platform replaces designed in 2004 by the computing system on the basis of OBC "Baguette". Work on the creation of a new system of "Integrated modular avionics weapons systems" (IMA BK) was conducted during the last four years. One of our customers — the Ministry of industry and trade of the Russian Federation. Computer system created on the basis of domestic multi-core microprocessors and new, domestic operating system real-time.4 million lines of code

In the integrated structure of the onboard equipment of the aircraft T-50 to the Central computer shall perform the functions of control systems of the aircraft, use of weapons, defense and a multi-mode smart support of the pilot. Central computer which simultaneously plays the role of pilot and electronic and electronic electronic Navigator and a flight engineer, in real time solves the problem of automatic detection and identification of the most dangerous purposes, to build the most optimal route, the optimal solution of problems of the use of weapons and defense aircraft, as well as reconfiguration of the system in case of failure. The new control system takes control of almost all key devices of the aircraft radar, navigation and communication in the previous version of the aircraft to calculate functions of each system used its calculator.The amount of its onboard software has already exceeded 4 million lines of code, and still further to implement a number of complex functional control modes LA and complex information processing."The new system is indeed innovative and has no analogues in the world, — says Dmitry Mushrooms. — We first went along the path of reproduction is already implemented by other decision makers, and provided a promising architecture, which will continue to develop in the direction of "network side", consistently upgrading onboard systems and complexes. Multi-core gives us almost unlimited possibilities for designing fault-tolerant hardware configurations, while saving on weight, power consumption and cost of equipment."The data is exchanged via fibre-optic channels. The transition from copper to fiber optics has allowed us to increase the speed and volume of data transmission, in order to reduce the weight of the cable network and to improve its noise immunity. If data transmission over traditional copper cable gives the speed of the order of 10-100 Mbps, then the fiber is almost 1,000 times more — 8 Gbit/sec Network structure of the complex increases the reliability of all devices when failure of any computer there is an automatic switching system at the other unit, and the use of a centralized processor has allowed almost twice to reduce the weight of the device. The performance of OBC increased by more than ten times, accutanecost increased more than four times. For the first time in Russian history the head role in the implementation of the common platform design and development played an aircraft firm.For the first time in Russian history the head role in the implementation of the common platform design and development was assigned to aircraft company — OKB Sukhoi. When you create a new system sukhivtsi worked together with the leading domestic enterprises of concern "radio-Electronic technology" (KRET): Ryazan State instrument-making enterprise (rsie) and Ramensky instrument design Bureau (RPKB). In turn, the State research Institute of aviation systems" (GosNIIAS) performed modeling of functional applications of the T-50 new computing platform. Conclusion GosNIIAS was positive: IMA BC gave a significant increase in computing resources and speed of information processing.Taganrog IQ
One of the problems that faced the leadership of the Sukhoi design Bureau, training and retention of highly qualified software testers. Worldwide the major aircraft manufacturers and instrument engineers often turn to outsourcing is to attract programmers from India and Eastern Europe. To prepare a good specialist takes about two years. In Moscow because of the higher salaries of experienced testers take IT commercial structure. But because of the defense of the specifics to attract outsourcers from other countries was, of course, impossible.Sukhivtsi found an original solution by opening a branch in the city of Taganrog, where there are good professionals and Universities. In Taganrog have created a few dozen new jobs, and in recent years sukhivtsi from his native city of Anton Chekhov remains one of the most successful and loyal employees.The unlimited possibilities of multi-core
New computing platform has already attracted significant interest not only from the related airline and helicopter companies in Russia, but also the developers of computing systems for space and Navy. Indian experts have chosen the operating system of the development of the company "Sukhoi" for the joint project of a fifth generation fighter, rejecting the use of the famous American RV OS VxWorks and Integrity.Little-known fact that for the first time the popular concept of integrated modular avionics was implemented for French fighter Dassault Rafale, and after that was adapted for a wide range of civil and military transport aircraft — A380, A400, A350, SSJ100, and others. Military aircraft are not so strictly regulate the dealings with the regulatory documents and the certified requirements, as a civilian, where every change is possible only after a thorough verification and validation process. That's why the system on multi-core microprocessors began flight tests on military aircraft."Our objective is to maintain leadership in this field, speaking on the ideological locomotive of the solution of questions of integration of avionics equipment into the network architecture of the future", — says Dmitry Mushrooms.
