Abstract

System for maintaining a turbine engine comprising said turbine engine of an aircraft comprising: an oil reservoir, a sensor able to measure an oil level in the oil reservoir, a transmission device, such as electrical wires, wireless transmitter circuit, etc., for transmitting a signal coupled to said sensor in order to transmit information relating to an oil level measured by said sensor, communication means, such as a display or a near field communications circuit coupled to said transmission devices, for communicating to the outside of the aircraft information representing an oil level measured by said sensor. The maintenance system further comprises a mobile apparatus able to communicate with said communication means and comprising a display for displaying said information representing an oil level to an operator situated on the ground outside the aircraft.

Claims

1. System for maintenance of a turbine engine of an aircraft comprising:

a turbine engine further comprising;

an oil reservoir;

a sensor able to measure an oil level in the oil reservoir; and

a transmitter configured for transmitting a signal coupled to said sensor in order to transmit information relating to an oil level measured by said sensor;

wherein said turbine engine comprises communication means, coupled to said transmitter, for communicating to the outside of the aircraft information representing an oil level measured by said sensor; and

wherein said maintenance system comprises a mobile apparatus able to communicate with said communication means and comprising a display configured for displaying said information representing an oil level communicated by said communication means to an operator situated on the ground outside the aircraft.

2. The maintenance system of claim 1, wherein said communication means are able to communicate information representing an oil level measured by said sensor within a radius of no more than ten meters around said turbine engine.

3. The maintenance system of claim 1, wherein said display of said mobile apparatus comprises an LED or LCD screen.

4. The maintenance system of claim 1, wherein said display is configured to display said information permanently.

5. The maintenance system of claim 1, wherein said mobile apparatus comprises a control coupled to said display, configured to control the display of said information.

6. The maintenance system of claim 1, wherein said communication means comprise near-field communication means.

7. The maintenance system of claim 1, wherein said communication means comprise an RFID chip.

8. The maintenance system of claim 1, wherein said mobile apparatus is within a maximum radius of ten meters around said turbine engine.

9. The maintenance system of claim 1, further comprising processing means for processing a signal transmitted by the transmitter and estimation means able to estimate a requirement for filling said oil reservoir from the information transmitted by the transmitter.

10. The maintenance system of claim 9, wherein said processing and estimation means are incorporated in said mobile apparatus.

11. The maintenance system of claim 1, further comprising recording and storage means coupled to said transmitter for recording information relating to oil levels measured by said sensor.

12. Method for maintaining a turbine engine of an aircraft on the ground and comprising:

providing a turbine engine further comprising;

an oil reservoir;

a sensor able to measure an oil level in the oil reservoir;

a transmitter for transmitting a signal coupled to said sensor in order to transmit information relating to an oil level measured by said sensor; and

communication means, coupled to said transmitter, for communicating to the outside of the aircraft information representing an oil level measured by said sensor;

providing, in the vicinity of said turbine engine, a mobile apparatus able to communicate with said communication means and comprising a display for displaying information representing an oil level communicated by said communication means;

reading, outside the aircraft, said information communicated by the communication means by viewing a display on said mobile apparatus; and

deducing a fill level of said oil reservoir from said reading.

13. The method of claim 12, comprising processing, by said mobile apparatus, the information communicated by said communication means.

14. The method of claim 12, wherein said mobile apparatus is provided within a maximum radius of ten meters around said turbine engine.
