TSAMTO, April 19. The use of mathematical modeling in the aircraft industry using supercomputer technologies can already significantly reduce the time of work and financial costs.
Alexander Kornev, Chief Designer of supercomputer technologies at the Sukhoi Experimental Design Bureau (OKB), said this in an interview with the corporate publication of the United Aircraft Corporation (UAC, part of the Rostec State Corporation) – the Horizons magazine.
Sukhoi Design Bureau became one of the pioneers in the application of electronic product layout – the basic technology for the application of high-precision physical and mathematical models. "This step has been prepared for a long time, and now, when designing the Su-35, and then the Su-57, these technologies have become very widely used and give their effect," said Alexander Kornev. According to him, the quintessence of experience in creating an electronic layout was concentrated in the following works of the Design Bureau. So, according to him, when creating a fire extinguishing system for one of the new products, mathematical modeling with the use of supercomputer technologies made it possible to reduce the time of work several times and spend several dozen times less financial resources.
The Sukhoi Design Bureau's Center for Supercomputer Technologies has made many major achievements in the field of various multiphysical tasks, including models of aircraft movement at large angles of attack, unsteady aerodynamics in the event of control deflection and failure, and numerous tasks in the use of aircraft weapons and detachable cargo.
Today, one of the most promising tasks of the center is to create a comprehensive mathematical model that comprehensively and accurately describes all the components and working bodies of the aircraft. "For us, the future is coming now, we are already engaged in it today. We focus on the multi-connectivity of models – - said Alexander Kornev. – The aircraft has a lot of units that work simultaneously in different environments: hydrofluids, fuel, air, all kinds of gases, electricity. It is now possible to combine them and create a complex mathematical model describing all these components and working bodies using simplified models. But it is not possible to describe all the components of the aircraft at the same time because of the lack of computing resources." According to the chief designer of supercomputer technologies of the Sukhoi Design Bureau, when the creation of a complex mathematical model – comprehensive and high-precision-becomes possible, then when creating a new aircraft, one flight prototype will be enough. With its help, it will be possible to confirm the correctness of the mathematical models used in the development, after which the new aircraft can be launched in a series.
