PROBLEM TO BE SOLVED: To reliably detect leakage even at a small flow rate, which corresponds to a defect of a pipe at the initial stage, by using a linear sensor without requiring an expensive device.SOLUTION: A piping structure 10 included by an aircraft includes: a pipe 11 through which bleed air at higher temperature than the temperature of a surrounding atmosphere flows; a cover 13 which covers an outer peripheral part of the pipe 11 and which defines a plurality of vent holes 14 allowing the bleed air leaking from the pipe 11 to flow out; and guide members 17 for guiding the air flowing out from the vent holes 14 toward a linear sensor 31 which passes through a position corresponding to each of the plurality of vent holes 14 and which responds to the temperature or concentration of air outside the cover 13.SELECTED DRAWING: Figure 2

    【課題】高価な装置を必要とせず、線状のセンサを用いていながら、配管の初期段階の欠陥に対応する小流量のリークをも確実に検知すること。【解決手段】航空機が備える配管構造10は、周囲の雰囲気の温度よりも高い温度の抽気が流れる配管11と、配管11の外周部を覆い、配管11からリークした抽気を流出させる複数の通気孔14を規定するカバー13と、複数の通気孔14の各々に対応する位置を通り、カバー13の外側の気体の温度または濃度に感応する線状のセンサ31に向けて、通気孔14から流出した気体をガイドするガイド部材17とを備えている。【選択図】図2
