Abstract

An air data system with a digital interface includes least one air data component, a receiving system and at least one digital connection. The at least one digital connection is between the receiving system and the air data component. A method for transmitting data in an air data system with a digital interface includes measuring at least one air data parameter with at least one air data component. The method includes generating a digital signal representative of the at least one air data parameter with the at least one air data component, sending the digital signal to a receiving system, and processing the at least one air data parameter with the receiving system.

First claim

What is claimed is:

1. An air data system with a digital interface, the system comprising:
a plurality of sets of air data components, wherein each set of the plurality of sets of air data components includes an angle-of-sideslip (AOS) sensor, an angle-of-attack (AOA) sensor, a total-air-temperature (TAT) probe, an integrated Pitot probe, an integrated left-hand static port and an integrated right-hand static port, wherein said each set of the plurality of sets of air data components includes an integrated receiving portion and transducer;
a plurality of receiving systems external of the plurality of sets of air data components; and
respective digital connections between each receiving system of the plurality of receiving systems and said each set of the plurality of sets of air data components, wherein said each receiving system is configured and adapted to process at least one air data parameter from said each set of the plurality of sets of air data components to generate at least one air data characteristic.

2. The air data system as recited in claim 1 , wherein at least one of the respective digital connections is at least one of a wired digital connection between at least one of the plurality of receiving systems and at least one set of the plurality of sets of air data components or a wireless digital connection between said at least one of the plurality of receiving systems and said at least one set of the plurality of sets of air data components.

3. The air data system as recited in claim 1 , wherein said each set of the plurality of the sets of air data components is digitally connected to a respective one of the plurality of receiving systems.

4. The air data system as recited in claim 1 , wherein said each set of the plurality of sets of air data components includes a respective heating element, wherein the respective heating element is operatively connected to at least one of the transducer or one of the plurality of receiving systems for at least one of status monitoring or control inputs.

5. A method for transmitting data in an air data system with a digital interface, the method comprising:
measuring at least one air data parameter with a plurality of sets of air data components, wherein each set of the plurality of sets of air data components includes an angle-of-sideslip (AOS) sensor, an angle-of-attack (AOA) sensor, a total-air-temperature (TAT) probe, an integrated Pitot probe, an integrated left-hand static port and an integrated right-hand static port, wherein said each set of the plurality of sets of air data components includes an integrated receiving portion and transducer;
generating a digital signal representative of the at least one air data parameter from said each set of the plurality of sets of air data components;
sending the digital signal to at least one of a plurality of receiving systems external to the plurality of sets of air data components; and
processing the at least one air data parameter with the at least one of the plurality of receiving systems.

6. The method of claim 5 , wherein processing the at least one air data parameter includes generating at least one air data characteristic.

7. The method of claim 5 , wherein sending the digital signal to the at least one of the plurality of receiving systems includes sending the digital signal over at least one digital connection between the at least one of the plurality of receiving systems and at least one set of the plurality sets of air data components.

8. The method of claim 7 , wherein the at least one digital connection is at least one of a wired digital connection between the at least one of the plurality of receiving systems and the at least one set of the plurality of sets of air data components or a wireless digital connection between the at least one of the plurality of receiving systems and the at least one set of the plurality of sets of air data components.

9. The method of claim 5 , wherein measuring the at least one air data parameter includes measuring the at least one air data parameter with the integrated receiving portion of at least one set of the plurality of sets of air data components.

10. The method of claim 5 , further comprising at least one of monitoring or controlling a respective heating element of at least one set of the plurality of sets of air data components with at least one of the transducer or the at least one of the plurality of receiving systems.

11. The method of claim 5 , wherein measuring the at least one air data parameter includes measuring the at least one air data parameter linked to prognostics for at least one set of the plurality of sets of air data components.

12. The method of claim 11 , wherein processing the at least one air data parameter includes processing the at least one air data parameter linked to prognostics to determine a health status for the at least one set of the plurality of sets of air data components.

13. The method of claim 5 , wherein generating the digital signal includes generating the digital signal with the transducer of at least one set of the plurality of sets of air data components.

14. The method of claim 5 , wherein said each set of the plurality of sets of air data components is digitally connected to the at least one of the plurality of receiving systems with a respective digital connection.

15. The method of claim 5 , wherein said each set of the plurality of sets of air data components is digitally connected to the at least one of the plurality of receiving systems.
