REINFORCEMENT AND ANALYSIS OF CABIN DOOR AREAR STRUCTURE OF A CERTAIN TYPE OF LARGE AIRCRAFT WITH COMPOSITE FUSELAGE

The application of composite materials in commercial aircraft is increasing, and the wide body aircrafts with all-composite fuselage have appeared, in which the reinforcement of cabin door area structure of the composite fuselage is an important issue. With this regard, the paper performed finite element analysis and structure optimization of a certain typer of large aircraft with all-composite fuselage, and the results meet the requirement.
