Fuel tank for aircraft provided with a fuel heating system, and fuel heating system for aircraft fitted with such a tank

摘要

The fuel tank (10) is made as a flexible multilayer tank, wherein a cavity (16) is provided between two adjacent layers (10a, 10b) of the tank (10) and defines a path that extends along a bottom wall of the tank (10) between an inlet opening (18) and an outlet opening (20) of the tank (10). The path defined by the cavity (16) is intended to be passed through by a hot fluid in order to transfer heat to the fuel contained in the tank (10). Advantageously used as hot fluid is a fluid in vapour phase made available by a two-phase fluid heat exchanger (30), said fluid in vapour phase being cooled through the cavity (16) and leaving the outlet opening (20) of the tank (10) as fluid in liquid phase.
