Thermal Evaluation of Multilayer Wall with a Hat-Stringer in Aircraft Design

In the present paper, we investigate heat transfer through multilayer wall of aircraft cabins, as this process influences comfortable conditions created for most passengers and crew members. The numerical modelling results calculation a with hat-stringer in design are presented. thermal characteristics evaluation their relationship parameters were made. effect air layer size on overall resistance wall, taking into account geometrical dimensions properties surfaces, was studied. relative temperature field insulation layer, which crosses elements fuselage frame, is calculated. It shown that insufficient thickness material zone at low temperatures leads to significant deterioration characteristics, can worsen microclimatic inside cabin.
