Abstract: A nozzle configured to receive and disperse a high-pressure fluid or a low-pressure fluid is disclosed. The nozzle includes a nozzle body defining an open end, a closed end, and a side wall connecting the open end to the closed end, where the open end of the nozzle body configured to receive either the high-pressure fluid or the low-pressure fluid. The side wall defines a plurality of low-pressure apertures, a plurality of high-pressure apertures, and a compressible member positioned within the nozzle body. The plurality of high-pressure apertures are positioned downstream from the plurality of pressure apertures. The low-pressure apertures are smaller in size by a predefined ratio when compared to the high-pressure apertures. The compressible member is in an expanded position and blocks the plurality of high-pressure apertures when the open end of the nozzle body receives the low-pressure fluid.

Abstract: A fire suppression system for a compartment of an aircraft includes a sensor system, at least one valve, and a controller. The sensor system is located within the compartment and includes, at least, a first sensor and a second sensor. The first sensor is configured to detect atmospheric substances within the compartment and the second sensor is configured to detect combustion products within the compartment. The at least one valve is configured for regulating flow of a fire suppressant to the compartment. The controller is configured to control flow of the fire suppressant, via the at least one valve, in response to input from the sensor system. The controller provides instructions to discharge the fire suppressant if the first sensor detects atmospheric substances and the second sensor detects combustion products.
