The disclosure pertains to a plant for the production of ammonia. The ammonia is produced from hydrogen obtained by electrolysis of water. The electrolysis is powered by a renewable source of energy, complemented with power obtained from the plant during periods of low or no availability of the renewable energy. To this end, the plant is configured such that it can be operated in a charge configuration (obtaining and storing power) and a discharge configuration (employing said power).

Methods, apparatus, systems, and articles of manufacture are disclosed for a variable bleed valve assembly. An example variable bleed valve assembly a variable bleed valve (VBV) door corresponding to a bleed port and a first unison ring, the VBV door coupled to the first unison ring, the first unison ring to move in a circumferential direction between a first position and a second position causing the VBV door to move between the first position and the second position.

A thermal energy system for use with an aircraft includes a cooling loop and a cooler. The cooling loop includes a fluid conduit and a pump configured to move fluid through the fluid conduit to transfer heat from a heat source to the fluid in the fluid conduit to cool the heat source. The cooler includes an air-stream heat exchanger located in a duct and is in thermal communication with the fluid conduit to transfer heat between the fluid in the cooling loop and the air passing through the duct.

A method of detecting an airflow fault condition in a gas turbine engine, the method including: operating the gas turbine engine with a thermal transport bus having an intermediary heat exchange fluid flowing therethrough; determining a performance characteristic of the intermediary heat exchange fluid in the thermal transport bus is outside of a predetermined range, wherein the performance characteristic includes a temperature, a pressure, a flowrate, or a combination thereof; and indicating an airflow fault condition in response to determining the performance characteristic is outside of the predetermined range.

A spray nozzle assembly includes a nozzle body supporting a plurality of spray nozzles. The plurality of spray nozzles are divided into a plurality of different stages. The nozzle body includes a first fluid distribution passage that communicates with a first spray nozzle stage and a second fluid distribution passage that communicates with a second spray nozzle stage. A nozzle inlet includes a plurality of fluid inlets including a first fluid inlet that communicates with the first fluid distribution passage of the nozzle body and a second fluid inlet that communicates with the second fluid distribution passage of the nozzle body. Control of fluid flow through the first fluid distribution passage to the first spray nozzle stage and through the second fluid distribution passage to the second spray nozzle stage adjusts a total spray volume or a flow rate of the spray nozzle assembly.
