Abstract
A fire suppression system for a gas turbine engine includes a fire suppressant delivery circuit, a first nozzle and a multi-directional nozzle. The fire suppressant delivery circuit includes and extends between an upstream inlet and a downstream distal end. The first nozzle is fluidly coupled with the fire suppressant delivery circuit and is disposed at the downstream distal end. The multi-directional nozzle is fluidly coupled with the fire suppressant delivery circuit and is configured serially inline between the upstream inlet and the first nozzle.

A fire suppression system for a gas turbine engine, comprising:
- a fire suppressant delivery circuit including and extending between an upstream inlet and a downstream distal end;
- a first nozzle fluidly coupled with the fire suppressant delivery circuit and disposed at the downstream distal end;
- and
- a multi-directional nozzle fluidly coupled with the fire suppressant delivery circuit and configured serially inline between the upstream inlet and the first nozzle, the multi-directional nozzle including:
- a tubular upstream fitting including an upstream fitting inlet and an upstream fitting outlet, wherein the upstream fitting inlet is fluidly coupled with the upstream inlet of the fire suppressant delivery circuit;
- a tubular downstream fitting including a downstream fitting inlet and a downstream fitting outlet that is fluidly coupled with the first nozzle;
- a coupling nut configured to attach the downstream fitting to the upstream fitting, wherein the downstream fitting inlet is fluidly coupled with the upstream fitting outlet;
- and
- a plurality of nozzles orifices extending through the coupling nut, wherein each of the nozzle orifices is fluidly coupled with an inner bore of the multi-directional nozzle.
An assembly of a fire suppression system for a gas turbine engine, the fire suppression system comprising a first fluid line and a second fluid line, the assembly comprising:
- a multi-directional pass-through nozzle including a tubular upstream fitting, a tubular downstream fitting, a coupling nut and a plurality of nozzle orifices;
- the upstream fitting including an upstream fitting inlet and an upstream fitting outlet, wherein the upstream fitting inlet is configured to be fluidly coupled with and receive fire suppressant from the first fluid line;
- the downstream fitting including a downstream fitting inlet and a downstream fitting outlet, wherein the downstream fitting outlet is configured to be fluidly coupled with and provide a portion of the fire suppressant to the second fluid line;
- the coupling nut attaching the downstream fitting to the upstream fitting, wherein the downstream fitting inlet is fluidly coupled with the upstream fitting outlet;
- and
- the nozzle orifices extending through the coupling nut, wherein each of the nozzle orifices is fluidly coupled with an inner bore of the multi-directional nozzle.
An assembly comprising:
- a gas turbine engine;
- and
- a fire suppression system including a fire suppressant delivery circuit, a first nozzle and a multi-directional nozzle, wherein the first nozzle and the multi-directional nozzle are configured to direct fire suppressant towards components of the gas turbine engine;
- the fire suppressant delivery circuit including and extending between an upstream inlet and a downstream distal end;
- the first nozzle fluidly coupled with the fire suppressant delivery circuit and disposed at the downstream distal end;
- and
- the multi-directional nozzle fluidly coupled with the fire suppressant delivery circuit and configured between the upstream inlet and the first nozzle.
