The A.M. Lyulka Design Bureau (part of UEC-UMPO of the United Engine Corporation) is recording a trend towards reducing testing with mathematical calculations. This was announced by Georgy Gogaev, the company's leading product designer, at the V Congress of Young Scientists in Sirius.
He noted that this approach is far from innovative and has been around for decades, but there are already good results in this direction.
Here I would also like to note that we are talking about not reducing the number of tests, but replacing them with calculations. For this, of course, we need verified high-level mathematical models that take into account a large number of factors and their mutual influence. That is, models that will reliably describe the real operating conditions of the engine.
Gogaev cited three strategies for establishing the life of an engine. The first strategy involves testing the entire engine, which is long and expensive.
The second strategy is to establish the life of the main parts, the destruction of which can lead to an emergency or catastrophic situation, but still through testing.
The third concept involves establishing the life of the main parts based on the results of calculations.
Naturally, in order to arrive at the third strategy, it is necessary to carry out a large complex of works, which involves the creation of interdisciplinary models, verified mathematical models, and the availability of a database on the structural strength of the material. We are currently on the first strategy, but, as I said, work is underway towards the third strategy.
As a reminder, the A. M. Lyulka Design Bureau is the key developer of the AL-41F family of engines for the Su-57 and Su-35S fighters, and is engaged in the entire range of work on their design, testing and improvement.
