An aircraft door 18 which closes an opening of a storage space 16 for storing a RAT 13 as an accessory and which is opened in association with deployment of the RAT 13 from the storage space 16, the door including: a door body 20 that opens and closes the opening, and whose front surface faces an ou
An aircraft door 18 which closes an opening of a storage space 16 for storing a RAT 13 as an accessory and which is opened in association with deployment of the RAT 13 from the storage space 16, the door including: a door body 20 that opens and closes the opening, and whose front surface faces an outside and whose rear surface faces the storage space 16 in a closed state; and a fence 24 that rises from the rear surface of the door body 20. In a traveling direction of the aircraft, the fence 24 is located anterior to a position where the RAT 13 is stored. The fence 24 prevents an airflow Air from passing through between the RAT 13 and the door body 20 in an initial stage where the door 18 starts to be opened, thereby suppressing the aerodynamic force in the closing direction acting on the door body 20.

1. An aircraft door which closes an opening of a storage bay of an aircraft for storing an accessory and which is opened in association with deployment of the accessory from the storage bay, the door comprising: a door body that opens and closes the opening and establishes a gap between the door body and the accessory when an opening degree of the door is within a predetermined range, and whose front surface faces an outside and whose rear surface faces the storage bay in a closed state;a fence that rises from the rear surface of the door body and extends longitudinally in a transverse direction across a traveling direction of the aircraft, the fence having a height relative to a length of the gap suitable to prevent at least a portion of an airflow from passing through the gap when the door is opened within the predetermined range, and allow at least a portion of an airflow to pass through the gap when the door is opened beyond the predetermined range to a fully-open state,wherein in a traveling direction of the aircraft, the fence is located anterior to a position where the accessory exists; anda connector that cooperates with a portion of the aircraft to allow the door body to open and form the gap having a variable distance between the door body and the accessory as the opening degree of the door is adjusted under control of an actuator within the predetermined range. 2. The aircraft door according to claim 1, wherein in the traveling direction, the fence is located anterior to a position which substantially corresponds to a rear end portion of the accessory. 3. The aircraft door according to claim 1, wherein in the traveling direction, the fence is located anterior to a position which substantially corresponds to a front end portion of the accessory. 4. The aircraft door according to claim 1, wherein the accessory is arranged within a range of a region occupied by the fence in a direction perpendicular to the traveling direction as viewed along the traveling direction. 5. The aircraft door according to claim 1, wherein the accessory is a ram air turbine. 6. The aircraft door according to claim 1, wherein the fence is oriented in a direction substantially perpendicular to the rear surface of the door body. 7. The aircraft door according to claim 1, wherein the fence is provided at a position not interfering with the accessory, when the accessory is in contact with the door body with no gap between the accessory and the door body in a stored state. 8. The aircraft door according to claim 1, wherein the door is driven by an actuator. 9. An aircraft comprising the aircraft door according to claim 1. 10. The aircraft door according to claim 1, wherein the fence is configured so as to prevent the airflow from passing between the accessory and the door body in an initial stage where the closed door starts to be opened in association with the deployment of the accessory from the storage bay. 11. The aircraft door according to claim 10, wherein the fence is configured so as to allow the airflow to pass between the accessory and the door body after the door body has been opened beyond the initial stage where the closed door starts to be opened. 12. An aircraft door which closes an opening of a storage bay of an aircraft for storing an accessory and which is opened in association with deployment of the accessory from the storage bay, the door comprising: a door body that opens and closes the opening and establishes a gap (G) between the door body and the accessory when an opening degree of the door is within a predetermined range, and whose front surface faces an outside and whose rear surface faces the storage bay in a closed state; anda fence that rises from the rear surface of the door body and extends longitudinally in a transverse direction across a traveling direction of the aircraft, the fence having a height (H) that is greater than or equal to a length (h) of the gap (G) when the opening degree of the door is within the predetermined range to prevent at least a portion of an airflow from passing through the gap when the door is opened within the predetermined range, the fence further comprising a width (W) that is greater than or equal to a width (w) of the accessory, and the fence allows at least a portion of an airflow to pass through the gap when the door is opened beyond the predetermined range to a fully-open state, wherein in a traveling direction of the aircraft, the fence is located anterior to a position where the accessory exists. 13. The aircraft door according to claim 12, wherein the accessory is a ram air turbine. 14. The aircraft door according to claim 12, wherein the fence is oriented in a direction substantially perpendicular to the rear surface of the door body. 15. An aircraft comprising the aircraft door according to claim 12. 16. The aircraft door according to claim 12, wherein the fence is configured so as to prevent the airflow from passing between the accessory and the door body in an initial stage where the closed door starts to be opened in association with the deployment of the accessory from the storage bay. 17. The aircraft door according to claim 16, wherein the fence is configured so as to allow the airflow to pass between the accessory and the door body after the door body has been opened beyond the initial stage where the closed door starts to be opened.
