Systems and methods are provided for storage in at least one on-board fuel tank of aircraft fuel under a predetermined pressure and at an internal ambient tank temperature. A passive heat exchanger having an exchanger inlet is fluid-connected to a propulsion engine of the aircraft to receive heated pressurized bleed air therefrom while an exchanger outlet is fluid connected to the fuel tank. The passive heat exchanger is configured to cool the heated pressurized bleed air from the engine by heat transfer to a surrounding environment by radiation and convection so as to supply pressurization air to the fuel tank at the predetermined internal tank pressure and the internal ambient tank temperature. A system controller is provided to provide the fuel tank with pressurized air at a predetermined temperature during various aircraft flight phases.
本文提供了飞行器燃料箱加压系统和方法,具体地用于在预定压力和内部周围箱温度下将飞行器燃料储存在至少一个机载燃料箱内的系统和方法。具有交换器进口的被动热交换器流体连接到飞行器的推进发动机,以在交换器出口流体连接到燃料箱的同时接收受热加压引气。被动热交换器被构造成通过借助于辐射和对流对周边环境的热传递而冷却来自发动机的受热加压引气,以便在预定的内部箱压力和内部周围箱温度下将加压空气供应到燃料箱。提供了一种系统控制器,以在各种飞行器飞行阶段将处于预定温度的加压空气提供给燃料箱。
