摘要： An outer surface of a part of an airframe includes a mixed region in which a first color similar to a color applied to an adjacent region and a second color having a lower absorption rate of sunlight than the first color are mixed in a predetermined color distribution pattern. A reflective material that contributes to an increase in a reflection rate of sunlight is added to a part to which at least the first color is applied in the mixed region.

摘要： To prevent overheating of a structural member such as a pivot bulkhead facing a rear side of a fire wall to maintain the temperature of the structural member at allowable temperature or lower. An aircraft of the present invention includes: a fire wall resistant to flame; a structural member facing a rear side of the fire wall; and a skin surrounding the fire wall and the structural member. The structural member includes a guide member and a heat shielding member. The structural member guides, upward, air existing on the rear side of the fire wall, and the heat shielding member shields the guide member from heat radiated by the fire wall.

摘要： Under constraints on the space and the weight of an aircraft, the present invention aims to protect structural members from a heat generation part. An aircraft includes: a fuselage; an air conditioning pack installed on the outside of a lower part of the fuselage; a fairing covering the air conditioning pack; an outer heat insulation material disposed in a region of the fuselage, which corresponds to the air conditioning pack, from the outside of the fuselage; and an inner heat insulation material disposed around the region on the inside of the fuselage.

摘要： A structure for anti-adhesion of high-temperature air according to the present invention includes: a high-temperature air duct that is provided in an accessory of an aircraft and allows high-temperature air likely to be higher than a specified temperature to flow through the high-temperature air duct; an exhaust port that discharges a flow of the high-temperature air led through the high-temperature air duct, to an outside of the airframe; and a low-temperature air supplying part that supplies a flow of low-temperature air lower in temperature than the high-temperature air discharged to the outside of the airframe, to an airframe surface. The low-temperature air supplying part is configured to form an air layer made of a flow of low-temperature air between the high-temperature air that is bent toward the airframe surface in flight of the aircraft, and the an airframe surface.

摘要： To provide a fuel pipe of an aircraft that makes it possible to maintain temperature of fuel in the fuel pipe at appropriate temperature while giving consideration to reliability that is constantly required for the aircraft. A fuel pipe provided in an airframe of the aircraft includes: an inner pipe defining a flow path through which fuel flows; and an outer pipe surrounding an outer periphery of the inner pipe. A gap is provided between the outer periphery of the inner pipe and an inner periphery of the outer pipe. The inner pipe is made of a rubber material, and the outer pipe is made of a metal material.

摘要： An aircraft includes: a fairing which covers a lower part of a fuselage having a main landing gear bay (MLG bay), and defines a ventilation cavity communicating with the MLG bay between the fairing and the fuselage; and a heat removal system which removes heat generated from the MLG inside the MLG bay to the outside of the MLG bay by suctioning/discharging air through an inlet port and an outlet port leading from the ventilation cavity or the MLG bay to external air. The fairing defines a wheel opening through which a wheel of the MLG enters and exits, and defines a ventilation port, which functions as one of the inlet and outlet ports, between the fairing and an outer peripheral part of the wheel exposed from the wheel opening to the lower side of the MLG bay when the MLG is retracted.

摘要： Temperature of a structural member is maintained at allowable temperature or less by suppressing heat transfer from a high-temperature duct to the structural member. An insertion sheet according to the present invention is inserted between a flange and a partition panel. The flange is provided on a bleed duct and is fastened to the partition panel. The bleed duct penetrates through a partition wall of an aircraft. The insertion sheet includes first parts and a second part. The first parts are disposed near respective shafts of rivets provided at a plurality of positions of the insertion sheet. The second part extends among the first parts. The first parts bear a load of fastening, and the second part has thermal conductivity lower than thermal conductivity of the first parts.
