Abstract

Systems and methods for starting an engine on an aircraft are provided. One example aspect of the present disclosure is directed to an integrated starter for starting an engine on an aircraft. The integrated starter includes an air turbine starter. The integrated starter includes a starter air valve integrated with the air turbine starter. The integrated starter includes a controller configured to control the starter air valve. The starter air valve can be movable between a first position and at least a second position to regulate the flow of fluid into the air turbine starter. An output torque of the air turbine starter can be dependent at least in part on the flow of fluid into the air turbine starter.

First claim

What is claimed is:

1. An integrated starter for starting an engine on an aircraft comprising:
an air turbine starter comprising one or more starter sensors configured to determine a vibration and/or sound of a rotating portion of the air turbine starter;
a starter air valve integrated with the air turbine starter; and
a controller configured to control the starter air valve based at least in part on a notification from the one or more starter sensors indicative of such a vibration and/or sound,
wherein the starter air valve is movable between a first position and at least a second position to regulate the flow of fluid into the air turbine starter;
wherein an output torque of the air turbine starter is dependent at least in part on the flow of fluid into the air turbine starter.

2. The integrated starter of claim 1 , wherein the starter air valve comprises one or more valve sensors.

3. The integrated starter of claim 2 , where the one or more valve sensors comprise at least one of a pressure gauge, a vacuum gauge, and a manometer.

4. The integrated starter of claim 2 , wherein at least one of the one or more valve sensors is configured to measure a pressure.

5. The integrated starter of claim 2 , wherein at least one of the one or more valve sensors is configured to measure a temperature.

6. The integrated starter of claim 2 , wherein the starter air valve is further configured to adjust the opening of the starter air valve from a first open percentage to a second open percentage based on signals from the one or more valve sensors.

7. The integrated starter of claim 6 , wherein the air turbine starter comprises an air turbine motor.

8. The integrated starter of claim 6 , wherein the air turbine starter comprises a speed reducer.

9. The integrated starter of claim 1 , wherein the air turbine starter comprises an over-running clutch.

10. A method for starting an engine using an integrated starter, the method comprising:
adjusting an opening of a starter air valve integrated with an air turbine starter based at least in part on a signal from a controller, the air turbine starter comprising one or more starter sensors configured to determine a vibration and/or sound associated with a rotating portion of the air turbine starter, and the opening being adjusted based at least in part on a notification from the one or more starter sensors indicative of such a vibration and/or sound, the controller forming a part of the integrated starter;
providing fluid to the air turbine starter through the opening of the starter air valve;
converting the provided fluid with the air turbine starter into a torque output; and
starting the engine using the torque output of the air turbine starter.

11. The method of claim 10 , further comprising:
receiving a signal from one or more valve sensors.

12. The method of claim 11 , where the one or more valve sensors comprise at least one of a pressure gauge, a vacuum gauge, and a manometer.

13. The method of claim 11 , wherein at least one of the one or more valve sensors measures pressure.

14. The method of claim 11 , wherein at least one of the one or more valve sensors measures temperature.

15. The method of claim 11 , further comprising:
adjusting the opening of the starter air valve based on the signals from the one or more valve sensors.

16. The method of claim 15 , wherein the air turbine starter comprises an air turbine motor.

17. The method of claim 15 , wherein the air turbine starter comprises a speed reducer.

18. An aerial vehicle comprising:
an engine; and
an integrated air turbine starter configured to start the engine; the integrated air turbine starter comprising:
an air turbine starter comprising one or more starter sensors configured to determine a vibration and/or sound of a rotating portion of the air turbine starter;
a starter air valve integrated with the air turbine starter; and
a controller configured to control the starter air valve based at least in part on a notification from the one or more starter sensors indicative of such a vibration and/or sound,

wherein the starter air valve is movable between a first position and at least a second position to regulate the flow of fluid into the air turbine starter;
wherein an output torque of the air turbine starter is dependent at least in part on the flow of fluid into the air turbine starter.

19. The aerial vehicle of claim 18 , wherein the starter air valve comprises one or more valve sensors.

20. The aerial vehicle of claim 19 , wherein the starter air valve is further configured to adjust the opening of the starter air valve from a first open percentage to a second open percentage based on signals from the one or more valve sensors.
