Aircraft fuel system reduces flammability exposure of fuel tanks. In one embodiment, aircraft center fuel tank fuel is cooled in flight to reduce flammability exposure to be similar to that of an unheated metal wing tank. Fuel tanks having adjacent heat sources are insulated to minimize heat flow into the fuel. Fuel tanks having lower cooling properties, e.g., composite wing tanks, are cooled during flight so temperatures are reduced to be similar to metal wing tanks. A fuel tank, pressurized relative to outside pressure at altitude, having lower flammability exposure than unpressurized tanks and cooling fuel in the tank reduces flammability exposure of the fuel tank to be similar to that of an unpressurized metal wing tank. Recirculating flow from a tank, passing through heat exchanger, and returning to the tank cools fuel. A controller starts/stops fuel flow to tanks and uses sensors to command flow to reduce flammability.

Cooling oil is fed to a second oil space formed on the inner circumferential side of a hub member, and is also fed through a bypass oil passage to a first oil space formed on the outer circumferential side of a drum member. When the friction plates rotate, with grooves in the friction pads attached to the inner friction plates, the cooling oil flows by inertial force through oil holes in the hub member and through oil holes of the drum member, from the first oil space to the second oil space, and from the second oil space to the first oil space, respectively, through the friction plates. Accordingly, the flow of the cooling oil to the friction plates is improved without notches, etc. in the outer friction plates or in the inner friction plates, resulting in an improvement in cooling of the coupling device.
