The invention relates to a double-walled tube for an aircraft fuel system, an aircraft fuel system and an aircraft. The double-walled tube includes an inner wall defining a first open end, a second open end, and an interior region connecting the first open end to the second open end and via which fuel can flow through the double-walled tube in use. The double-walled tube also includes an outer wall disposed at least partially around the inner wall to define a void between the inner wall and the outer wall, the void being fluidly isolated from the interior region. The double-walled tube also includes at least one barrier that is openable to create a passage that fluidly connects the void to the interior region. The at least one barrier is configured to open when a pressure in the void is higher than a pressure in the interior region.
本发明涉及用于飞行器燃料系统的双壁管、飞行器燃料系统和飞行器。双壁管包括内壁,该内壁限定第一敞开端部、第二敞开端部和内部区域,该内部区域将第一敞开端部连接至第二敞开端部并且在使用中燃料能够经由内部区域流动通过双壁管。双壁管还包括外壁,该外壁至少部分地围绕内壁设置,以在内壁与外壁之间限定空隙,空隙与内部区域流体隔离。双壁管还包括至少一个屏障,该屏障能够打开以产生将空隙流体连接至内部区域的通路。至少一个屏障构造成在空隙中的压力高于内部区域中的压力时打开。
