The work solves the problem of the stress-strain state estimation of the heat exchange unit damper of the primary air handling system in modern transport aircraft, which is located in the air preparation system. It’s designed for air sampling from the engine's cruise unit or auxiliary power unit, its further processing and transportation to the life support system. When analyzing the stress-strain state of real aircraft structures, taking into account boundary conditions and load modes, analytical calculation methods are not always effective, therefore, numerical research methods were used in this work.Based on the finite element method, the stress-strain state analysis of the heat exchange unit damper was carried out, taking into account all the design features. Three-dimensional finite elements were used, which most accurately correspond to the calculation scheme. Numerical analysis of the stress-strain state made it possible to determine dangerous areas of stress where fatigue cracks may appear and destruction may be occur.
