Justification of sealing profiles application on transport aviation aircraft

Abstract

The diploma work considers a sealing profiles used for an aircraft pressurization. Subject of study is determination of fuselage sealing profiles characteristics for rapture, tension, compression ratio and friction. Aim of the master thesis is to solve the problem of choosing necessary type of sealing profiles and their fastening method to provide safety and needed operational conditions. Research was carried out using special equipment for a hydraulic press, a dynamometer and various measuring devices to ensure accurate indicators and research results. Novelty of the results demonstrate the strength and mechanical characteristics of the new sealing profiles developed for this aircraft model. Practical value is obtaining the necessary data that demonstrates the performance of sealing profiles and directly affects the safety of the flight and ensuring optimal operating conditions. The results of the work can be implemented in the selection of sealing profiles required for the mechanization of the fuselage to ensure optimal performance of pressurization.
