Abstract
A fence 30A is installed on an inner surface 21a of a door 20A on the side which faces a landing gear bay 15, the fence 30A rising inwardly of the airframe from the inner surface 21a. When the door 20A opens outwardly of an airframe due to a pressure difference between the side of an outer surface 21c of the door 20A and the side of an inner surface 21a facing inner part of the landing gear bay 15 during a flight of an aircraft 10, the fence 30A closes a gap between the door 20A and an opening 15a of the landing gear bay 15, and thereby prevents air from flowing into the landing gear bay 15 through the gap.
Claims20
An aircraft door which closes an opening formed in an airframe surface of an aircraft, comprising:
- a door body installed on the opening, the door body being movable between an open position and a closed position;
- and
- a fence installed at least on an outer periphery portion of the door body that faces a forward side of the airframe, the fence rising inwardly of the airframe from the door body,
- wherein when the door body opens outwardly of the airframe due to a differential pressure occurring between an outer side face of the door body facing outward of the airframe and an inner side face of the door body facing inward of the airframe during a flight of the aircraft, the fence closes a gap between an outer periphery of the opening and the outer periphery portion of the door body facing the forward side of the airframe.
An aircraft door which closes an opening formed in an airframe surface of an aircraft, comprising:
- a door body installed on the opening, the door body being movable between an open position and a closed position;
- and
- a fence installed at least on an outer periphery portion of the door body that faces a forward side of the airframe, the fence rising inwardly of the airframe from the door body,
- wherein the fence is a flat plate that extends along the outer periphery portion of the door body facing the forward side of the airframe.
An aircraft door which closes an opening formed in an airframe surface of an aircraft, comprising:
- a door body installed on the opening, the door body being movable between an open position and a closed position;
- and
- a fence installed at least on an outer periphery portion of the door body that faces a forward side of the airframe, the fence rising inwardly of the airframe from the door body,
- wherein the fence includes a curved plate portion curved convexly toward a rear part of the airframe.
