Abstract

An aircraft component assembly has an aircraft component for an aircraft. A sensor is configured to monitor the aircraft component. A local wireless transmitter is provided for communication with a remote receiver. In addition, a local wireless receiver is provided for communication with the remote transmitter. A processor is in communication with the sensor. The processor is configured to control the sensor, the local wireless transmitter and the local wireless receiver. A power source is configured to generate energy proximate the installed aircraft component.

Claims

1. An aircraft component assembly, comprising:

an aircraft component for an aircraft;

a sensor module having;

a sensor configured to monitor said aircraft component;

a local wireless transmitter for communicating with a remote receiver while said aircraft is in flight, wherein said remote receiver is remote from said component, and wherein said remote receiver is a component of a computer at a ground facility;

a local wireless receiver for communicating with a remote transmitter, wherein said remote transmitter is remote from said component;

a processor in communication with said sensor, said processor configured to control said sensor, said local wireless transmitter, and said local wireless receiver; and

a power source powering one of said sensor, said local wireless transmitter, said local wireless receiver and said processor, said power source generating energy from an environment surrounding the aircraft or the aircraft component when said aircraft component is installed on the aircraft and using the generated energy to power at least one of the sensor, the local wireless transmitter, the local wireless sensor, and the processor.

2. The aircraft component assembly of claim 1 including a memory unit in communication with said processor.

3. The aircraft component assembly of claim 1 wherein said power source obtains energy from vibration proximate said aircraft component.

4. The aircraft component assembly of claim 1 wherein said power source obtains energy from a temperature differential proximate said aircraft component.

5. The aircraft component assembly of claim 1 wherein said power source obtains energy from static electricity proximate said aircraft component.

6. The aircraft component assembly of claim 1 wherein said power source obtains energy from mechanical movement proximate said aircraft component.

7. The aircraft component assembly of claim 1 wherein said aircraft component is one of an engine component, an environmental control component, an auxiliary power component, or a slat component.

8. The aircraft component assembly of claim 1 wherein said processor has programming for authentication with a remote computer.

9. An aircraft sensor assembly for monitoring an aircraft component, comprising;

a sensor configured to monitor an aircraft component;

a local wireless transmitter for communicating with a remote receiver while an aircraft containing said aircraft component is in flight, wherein said remote receiver is remote from said component, and wherein said remote receiver is a component of a computer at a ground facility;

a local wireless receiver for communicating with a remote transmitter, wherein said remote transmitter is remote from said component;

a memory unit;

a processor in communication with said sensor, said processor configured to control said sensor, said local wireless transmitter, said local wireless receiver and said memory unit; and

an energy generator that generates energy from an environment surrounding the aircraft or the aircraft component when said aircraft component is installed on the aircraft and that powers at least one of said sensor, said local wireless transmitter, said local wireless receiver, said processor and said memory unit.

10. The aircraft sensor assembly of claim 9 wherein said energy generator source obtains energy from vibration proximate the aircraft component.

11. The aircraft sensor assembly of claim 9 wherein said energy generator source obtains energy from a temperature differential proximate the aircraft component.
