Structural Analysis of Rear Pressure Bulkhead of Typical Transport Aircraft

In this study, many researchers studied flat bulkhead, but Dome-shaped bulkhead is more preferable as it withstands pressure loads. We modeled a rear pressure bulkhead of a typical transport aircraft using CATIA V5 modeling software. Finite element analyses were carried out by the rear pressure bulkhead subjected to the boundary conditions (Fuselage is fixed and attached to the aircraft honeycomb structure and 0.1Mpa pressure is applied to the bulkhead). From the FEA of the rear pressure bulkhead, we obtained Von-Misses stresses and the deformations were obtained. The maximum displacement of 5.46mm was observed on the dome. The maximum normal stress at the circumferential direction was about 306Mpa.
