Aircraft door structure with an air flow system

摘要

A door and its frame especially in an aircraft are constructed for circulating air through the structure for preventing cold air from forming near the door in an aircraft cabin. For this purpose at least one air flow channel is provided in the door construction. The air flow channel communicates with at least one inlet port with at least one outlet port so positioned that air circulation is maintained through the door structure. The outlet port passes preferably through a cabin floor for discharging cold air into a space below the cabin floor.
