Rear pressure bulkhead
From Wikipedia, the free encyclopedia
The rear pressure bulkhead is a component of all large commercial aircraft. It is an airtight bulkhead located between the cabin and the tailfin. Its purpose is to seal the rear of the plane and thus maintain cabin pressure, and as such it is a vital part of the aircraft. The bulkhead is also designed to blow first should the cabin pressure become too high as opposed to the main fuselage of the aircraft.
