Sounds from airliners are harmful to the environment. Therefore, the standards for noise on the ground of the International Civil Aviation Organization (specialized agency of the United Nations) are regularly tightened, and failure to comply with them threatens air carriers with large fines. Now Russia does not have its own civil aircraft certified according to the new requirements. Perm Polytech scientists have developed a technology that will reduce the noise level of airliners and ensure the competitiveness of the Russian Federation. For the first time in world practice, they modeled processes in multilayer sound-absorbing structures, taking into account the conditions occurring in real aircraft engines.

Before the construction of buildings, engineering and geological surveys are always carried out and the characteristics of the soil are studied. This is necessary  in order to avoid excessive settlement of the soil base of the foundation. Nowdays, expensive and more cost-effective methods are used for calculations, but they are not always accurate. Developers from the Perm Polytech University created a neural network that will make it possible to predict soil settlement without additional research.

The leading engineering university in the region is included in two international rankings: the Times Higher Education World University Rankings 2022 and the Moscow International Ranking “Three University Missions”.

When receiving potash fertilizers, millions of tons of solid salt waste are generated, which cause significant environmental damage. Scientists of the Perm Tech believe that they can become raw materials for the medical, food and household industries, as well as for oil refining and glass production if they will be processed in a proper way. Chemists have developed a technology that allows them to dispose this fertilizers safely, removing insoluble impurities. The method for processing salt waste has no analogues and there is no need in expensive reagents.
