A significant problem in the aircraft industry remains the production of reliable hydro-gas systems, such as flight control, landing gear retraction and release, wheel turn control of the front landing gear, control of air brakes and spoilers, engine thrust reversal control, et al., providing a high degree of performance and reliability. The article discusses the technological processes of manufacturing parts for hydro-gas systems of aircraft. Research has been carried out on the expansion of the middle part of thin-walled tubular billets by cold plastic deformation, which showed that the most dangerous is the middle part of the considered part of the billet, where there are significant tensile stresses. The reduction in tensile stresses that occurs when creating an ice retainer allows to increase in the expansion ratio. The application of new types of working bodies is proposed for transferring pressure to the deformation zone.
