摘要： A fuel storage system is disclosed having a fuel tank configured to store a liquid fuel; a controllable pressure source for altering the pressure in an ullage space of the fuel tank; and a controller. The controller is configured to determine a target pressure for the ullage space at a given time based on information relating to a temperature of fuel inside the fuel tank at the given time; and to control the pressure source such as to cause the pressure in the ullage space to be substantially equal to the target pressure.

摘要： The invention aims at pressurising a volume (2) that needs to have a relative air pressure, in comparison with an ambient pressure, where the ambient air pressure can change rapidly and with large amplitude and where the access to pressurised air is limited. This is solved by a half open system comprising two parallel regulators (9) and (17) and two ejectors (15) and (19) working according to a split range control principle. When the relative air pressure difference is above a desired value of the second regulator (17), only the first regulator and the first ejector work. When the relative air pressure difference is below the desired value of the second regulator (17), both regulators (9) and (17) and ejectors (15) and (19) work. In this way the pressure inside the volume (2) can adapt rapidly to the changes in the ambient pressure, without leaking too much air during a static condition.
摘要翻译：本发明旨在将环境空气压力能够快速变化并且具有大幅度的变化以及对加压空气的进入受到限制的情况下，与需要具有相对空气压力的体积（2）加压。这通过包括两个平行调节器（9）和（17）以及两个喷射器（15）和（19）的半开启系统来解决，该喷射器（15）和（19）根据分段控制原理工作。当相对气压差高于第二调节器（17）的期望值时，仅第一调节器和第一排出器工作。当相对气压差低于第二调节器（17）的期望值时，调节器（9）和（17）和喷射器（15）和（19）都工作。以这种方式，体积（2）内的压力可以快速适应环境压力的变化，而不会在静止状态下泄漏太多的空气。

摘要： An aircraft fuel tank ventilation system includes a dehumidifying device disposed in flow communication between a vent open to the atmosphere and a fuel tank. A method of dehumidifying air introduced into an aircraft fuel tank via a ventilation system includes directing atmospheric air through a dehumidifying device disposed in flow communication between a vent of the ventilation system and the fuel tank, which removes water vapour from the air flowing from the vent towards the fuel tank. A method of regenerating a desiccant medium used to dehumidify air introduced into an aircraft fuel tank via a ventilation system includes directing air through the desiccant medium so as to dry the desiccant medium.

摘要： A rollonet designed to provide positive displacement of liquid rocket prolants for missle tankage comprising an inner and outer diaphragm each in the form of a continuous cylinder with a piston head therebetween. Gas pressure acting on the piston head imparts an axial thrust on the prerolled portions of the inner and outer cylinders, causing them to roll through 180.degree. away from the tank wall in a progressive manner.
