    摘要: An aircraft fuel system comprises a fuselage tank and wing fuel tanks each connected to the fuselage fuel tank by a respective fuel line. A first fuel line connects the fuselage fuel tank to a collector fuel tank, which is connected by second fuel lines to aircraft engines in use of the system. Unspent fuel output from the aircraft engines is returned to the collector fuel tank via third fuel lines. A fuel line arrangement is arranged to draw fuel from, and return that fuel to, the wing fuel tanks. Fuel within the third fuel lines is thermally coupled to fuel within the fuel line arrangement by a heat exchanger. Heat energy within unspent fuel output from the aircraft engines is transferred to the wing fuel tanks, reducing the likelihood of fuel freezing within these tanks during extended flying in cold environments.

    摘要: A cooling system for an interior space of a vehicle comprises a main cooling system coupled with an air inlet for receiving air and coupled with the interior space for providing cooled air to the interior space, at least one air duct arranged between the air inlet and the interior space, a reservoir for liquid nitrogen having a nitrogen outlet and a valve arranged between the outlet and an injection port of the at least one air duct. The reservoir is couplable with the injection port of the at least one air duct via the valve on demand for evaporating nitrogen in the at least one air duct. With the injection of liquid nitrogen the main cooling system is supported in case it is not able to provide a sufficient cooling power.
