Abstract

An environmental control system assembly for an aircraft is provided. The assembly includes: an environmental control system; a fuel cell assembly in electrical communication with the environmental control system for providing electrical power to the environmental control system; and a controller operably connected to the fuel cell assembly, the controller operable to modulate an amount of power generated by the fuel cell assembly and provided to the environmental control system based on load forecasting data from an ECS load forecasting module of the controller.

Claims (25)

1. An environmental control system assembly for an aircraft, the assembly comprising:

an environmental control system;

a fuel cell assembly in electrical communication with the environmental control system for providing electrical power to the environmental control system; and

a controller operably connected to the fuel cell assembly, the controller operable to modulate an amount of power generated by the fuel cell assembly and provided to the environmental control system based on load forecasting data from an ECS load forecasting module of the controller.

2. The assembly of claim 1 , wherein the ECS load forecasting module determines the load forecasting data based on a passenger number for the aircraft, weather forecast data, historical data, or a combination thereof.

3. The assembly of claim 1 , wherein the ECS load forecasting module determines the load forecasting data based on a passenger number for the aircraft.

4. The assembly of claim 1 , wherein the ECS load forecasting module defines an anticipated forecast timing of at least five minutes ahead and up to one hour ahead.

5. The assembly of claim 1 , wherein the ECS load forecasting module comprises a load forecasting model.

6. The assembly of claim 1 , wherein the environmental control system is in airflow communication with a cabin of the aircraft, and wherein the fuel cell assembly is in airflow communication with the cabin of the aircraft for receiving a cabin exhaust airflow from the cabin.

7. The assembly of claim 1 , wherein the environmental control system comprises a compressor section, and wherein the fuel cell assembly is in airflow communication with the compressor section of the environmental control system for receiving a pressurized airflow from the environmental control system.

8. The assembly of claim 1 , wherein the controller further comprises an objective function module, and wherein the controller is operable to modulate the amount of power generated by the fuel cell assembly and provided to the environmental control system based at least in part on the objective function module.

9. The assembly of claim 8 , wherein the objective function module is operable between one or more objective functions, the one or more objective functions selected from the following objective functions: maximum efficiency, maximum power output, maximum component life, and minimum emissions output.

10. The assembly of claim 1 , wherein the controller is operable to modify an operating condition of the fuel cell assembly to modulate the amount of power generated by the fuel cell assembly and provided to the environmental control system.

11. The assembly of claim 10 , wherein the operating condition comprises a fuel cell temperature, a current output, a fuel utilization, an air utilization, or a combination thereof.

12. The assembly of claim 1 , wherein the controller is operable to modulate the amount of power generated by the fuel cell assembly and provided to the environmental control system based on a feedback control scheme and a feedforward control scheme.

13. A method of operating an environmental control system assembly for an aircraft, the method comprising:

determining ECS load forecasting data for an environmental control system of the environmental control system assembly; and

controlling a fuel cell assembly in electrical communication with the environmental control system to modulate an amount of power generated by the fuel cell assembly and provided to the environmental control system in response to the determined ECS load forecasting data.

14. The method of claim 13 , wherein determining the ECS load forecasting data for the environmental control system comprises receiving data from a source external from the environmental control system assembly.

15. The method of claim 13 , wherein determining the ECS load forecasting data for the environmental control system comprises receiving data indicative of a passenger number for a flight operation of the aircraft.

16. The method of claim 13 , wherein determining the ECS load forecasting data for the environmental control system comprises determining the ECS load forecasting data for the environmental control system with an ECS load forecasting module.

17. The method of claim 16 , wherein determining the ECS load forecasting data for the environmental control system with the ECS load forecasting module comprises determining the ECS load forecasting data for the environmental control system with a load forecasting model of the ECS load forecasting module using load forecasting factors.

18. The method of claim 13 , wherein determining ECS load forecasting data for the environmental control system of the environmental control system assembly comprises determining the ECS load forecasting data based on a passenger number for the aircraft, weather forecast data, historical data, or a combination thereof.

19. The method of claim 13 , wherein determining ECS load forecasting data for the environmental control system of the environmental control system assembly comprises determining the ECS load forecasting data based on a passenger number for the aircraft.

20. The method of claim 13 , wherein the environmental control system is in airflow communication with a cabin of the aircraft, and wherein the fuel cell assembly is in airflow communication with the environmental control system, the cabin of the aircraft, or both.
