The study shows the importance of creating cryogenic pipelines for propulsion systems of aircraft from combined materials based on an ultra-thin steel liner and wound carbon fiber reinforced plastic. We analyzed the pipeline’s cooldown to cryogenic temperatures and found out that due to a significant difference in coefficients of linear thermal expansion of the liner and carbon fiber reinforced plastic materials, the axial stability can be lost with the formation of plications in a thin-walled steel shell. We suggest a technique for determining and selecting the angle of winding carbon fiber reinforced plastic, in which the axial deformations of a thin-walled liner and a wound composite will have the same level of deformation.
