10、ui, C. 2. Integrated Aircraft Thermal Management examples include the JP-8+100 additives, detailed in 5, and fuel deoxygenation. The prevailing approach to increasing the fuel heat sink capacity is to inject additives into jet fuel to give it anti-coking properties. The viability of on-board, real-t

11、ime fuel deoxygenation is still very much in an exploratory phase in the industry. Three technologies which appear to have promise are described below. These technologies, while showing promise, are very preliminary. None of the systems mentioned here have yet to address the sizing of equipment or h

12、ow the technology can be installed into an aircraft Advanced Deoxygenation System Concept The deoxgenation concept is centered on removing the oxygen molecules dissolved in the fuel, thereby raising the coking limit. One such system is conceptually shown in Figure 8. The system is a modification of

13、the traditional sparging method. This advanced deoxygenation system leads fuel into a reactor called the Contactor, so named because it brings fuel into contact with an inert gas (initially nitrogen). The breakthrough is the Contactors porous medium that acts as a fixed bed. This porous medium allow

14、s a continuously “changing and renewing” gas-liquid interface - which is intended to enhance the transfer kinetics between the inert gas and the fuel. The gas-fuel mixture that comes out of the Contactor is referred to as “froth.” Froth enters a gas-liquid Separator, so named because it breaks down froth into deoxygenated fuel and an oxygen-laden off-gas and then separates them.
