bulkhead
Other forms: bulkheads
The divider or wall between sections of a plane or large ship is called a bulkhead. When you're seated in first class on a jet, there's a bulkhead between you and the pilot's cabin.
The bulkhead you're most likely to see is in a commercial airliner, dividing the flight crew from the passengers and sometimes the first class flyers from those in coach. Other vehicles have them too, including submarines and ships — these bulkheads help strengthen the vessels and keep different areas watertight. The Old Norse root of bulkhead is bálkr, "partition."
