The present invention provides a pipe structure including: a pipe through which a gaseous body having a higher temperature than a temperature of a surrounding atmosphere flows; a cover that covers an outer peripheral portion of the pipe, and defines a plurality of vents from which the gaseous body leaking from the pipe flows out; and a line-shaped sensor that passes a position corresponding to each of the plurality of vents, and is sensitive to a temperature or a concentration of the gaseous body outside the cover, wherein the sensor includes a range in which the sensor rises upward from the position corresponding to the vent.

Pipe structure and aircraft

The present invention provides a pipe structure including: a pipe through which a gaseous body having a higher temperature than a temperature of a surrounding atmosphere flows; a cover that covers an outer peripheral portion of the pipe, and defines a plurality of vents from which the gaseous body leaking from the pipe flows out; and a guide member that guides the gaseous body flowing out from the vent toward a line-shaped sensor that passes a position corresponding to each of the plurality of vents, and is sensitive to a temperature or a concentration of a gaseous body outside the cover.

The present invention provides a pipe structure including a pipe that is disposed along an approximately horizontal direction, and has a plurality of ducts through which a gaseous body having a higher temperature than a temperature of a surrounding atmosphere continuously flows, and a plurality of couplings each connecting the ducts together; and a cover covering an outer periphery of the pipe. The cover defines a plurality of vents from which the gaseous body leaking from the pipe flows out of the cover at an interval in a length direction of the pipe. As the plurality of vents, the cover includes at least first vents located corresponding to the couplings. Respective positions of the first vents are substantially set within a range from a two o'clock position to a ten o'clock position through a six o'clock position in a cross sectional surface of the cover.

Pipe structure, aircraft, and method for giving robustness to leak detection

A fenceA is installed on an inner surfaceof a doorA on the side which faces a landing gear bay, the fenceA rising inwardly of the airframe from the inner surface. When the doorA opens outwardly of an airframe due to a pressure difference between the side of an outer surfaceof the doorA and the side of an inner surfacefacing inner part of the landing gear bayduring a flight of an aircraft, the fenceA closes a gap between the doorA and an openingof the landing gear bay, and thereby prevents air from flowing into the landing gear baythrough the gap.

Door of aircraft and aircraft having the same

An aircraft doorwhich closes an opening of a storage spacefor storing a RATas an accessory and which is opened in association with deployment of the RATfrom the storage space, the door including: a door bodythat opens and closes the opening, and whose front surface faces an outside and whose rear surface faces the storage spacein a closed state; and a fencethat rises from the rear surface of the door body. In a traveling direction of the aircraft, the fenceis located anterior to a position where the RATis stored. The fenceprevents an airflow Air from passing through between the RATand the door bodyin an initial stage where the doorstarts to be opened, thereby suppressing the aerodynamic force in the closing direction acting on the door body
