Abstract
Methods and systems for distributing an inert gas to an aircraft fuel tank are provided herein. The method includes channeling the inert gas in a first direction via a first distribution line and channeling the inert gas in an opposite second direction via a second distribution line. The second distribution line is concentrically aligned with and circumscribes the first distribution line. The second distribution line includes a termination point within the aircraft fuel tank. The second distribution line defines a plurality of distribution orifices that release of the inert gas into an ullage space of the fuel tank.

A gas distribution system comprising:
- a first distribution line configured to channel a gas in a first direction;
- and
- a second distribution line configured to channel the gas in an opposite second direction, said second distribution line concentrically aligned with and circumscribing said first distribution line, wherein said second distribution line includes a termination point within a fuel tank, wherein said second distribution line defines a plurality of distribution orifices that release the gas into an ullage space of the fuel tank.
A method of distributing an inert gas to an aircraft fuel tank, said method comprising:
- channeling the inert gas in a first direction via a first distribution line;
- and
- channeling the inert gas in an opposite second direction via a second distribution line, the second distribution line concentrically aligned with and circumscribing the first distribution line, wherein the second distribution line includes a termination point within the aircraft fuel tank, wherein the second distribution line defines a plurality of distribution orifices that release the inert gas into an ullage space of the fuel tank.
An aircraft inert gas system comprising:
- an inert gas generation system positioned within a fuselage of the aircraft;
- and
- an inert gas distribution system comprising:
- a first distribution line configured to channel inert gas in a first direction;
- and
- a second distribution line configured to channel the inert gas in an opposite second direction, said second distribution line concentrically aligned with and circumscribing said first distribution line, wherein said second distribution line includes a termination point within a fuel tank, wherein said second distribution line defines a plurality of distribution orifices that release the inert gas into an ullage space of the fuel tank.
