Presented work has an overview character and is focused on perspectives of sustainable aviation fuels application in civil aviation sector. The mean role of SAF application is to ensure reduction of greenhouse gas emissions and aviation footprint on environment. Paper describe the combustion proces of hydrocarbon fuels and problem related to the emission of carbon dioxide to the atmosphere. Fuel consumption, CO2 emission and SAF production data was presented on the graphs. The sustainalbe aviation fuel has been characterized. Certified conversion technologies with potential feedstock used for SAF production was described. Literature studies indicate that sustainable aviation fuel is successfully used in air transport.

The paper presents results of research on thin-walled load-bearing structure model representing a fragment of plane wing torsion box. The basis for obtaining data on deformation character and stability loss process was a model experiment conducted using a dedicated experimental stand. On the basis of experiment results, adequate numerical simulations were conducted using software based on finite elements method. Results of non-linear numerical analyses allowed to determine the character of stress distribution and formulate conclusions regarding behaviour of the post-critical deformations of the examined wing part.

This paper presents the results of experimental and numerical analysis in terms of the finite element method of plating components of aircraft load bearing structures. The subject matter of the study was composite panels with stiffeners in the form of a regular grid of oriented longitudinal elements in accordance with the directions of the principal stresses in the covering. The analysis was conducted in the buckling states of structural deformation which showed that structures with stiffeners exhibit much more favorable behavior in buckling deformation states than in laminar structures. This translates into stress distributions and their gradients, which are milder in forms of stiffened structures.
