Abstract

The invention relates to the field of aeronautical propulsion, and more specifically to an emptying and monitoring device and method for emptying and monitoring a fluid drained from an aircraft engine. The emptying and monitoring device comprises at least one first intake passage for receiving, directly from the aircraft, fluid drained from the engine, and a first quality sensor assembly for detecting at least one quality parameter of the fluid drained from the engine, having been admitted through the first intake passage.

First claim

The invention claimed is:

1. An emptying and monitoring device for emptying an on-board reservoir of a fluid drained from an engine of an aircraft and for monitoring the fluid drained from the engine of the aircraft, the emptying and monitoring device comprising:
an articulated pole incorporating an extensible first intake passage configured to establish a leak-tight connection with an emptying passage disposed on the aircraft for receiving, directly from the aircraft, the fluid drained from the engine, and
a first quality sensor assembly for detecting at least one quality parameter of the fluid drained from the engine having been admitted through the first intake passage.

2. The emptying and monitoring device according to claim 1 , wherein the first quality sensor assembly comprises a viscosity sensor for detecting a viscosity of the fluid drained from the engine.

3. The emptying and monitoring device according to claim 1 , wherein the first quality sensor assembly comprises a pollutant sensor assembly for detecting a presence of pollutants in the fluid drained from the engine.

4. The emptying and monitoring device according to claim 1 , further comprising, downstream of the first quality sensor assembly, at least one treatment device for treating the fluid drained from the engine having been admitted through the first intake passage.

5. The emptying and monitoring device according to claim 1 , further comprising:
a second intake passage for receiving, directly from the aircraft, fluid drained from the engine, and
a second quality sensor assembly for detecting at least one quality parameter of the fluid drained from the engine having been admitted through the second intake passage.

6. Fixed airport service installation comprising the emptying and monitoring device according to claim 1 .

7. The emptying and monitoring device according to claim 1 , wherein the articulated pole is also telescopic.

8. An airport service vehicle comprising the emptying and monitoring device according to claim 1 .

9. The airport service vehicle according to claim 8 , comprising an autonomous control device.

10. An emptying and monitoring method for emptying an on-board reservoir of a fluid drained from an engine of an aircraft and monitoring the fluid drained from the engine of the aircraft, the emptying and monitoring method comprising the following steps:
connecting, in a leak-tight manner, an extensible first intake passage, incorporated in an articulated of an emptying and monitoring device,
admitting, through the first intake, of fluid drained from the engine of the aircraft directly from the aircraft, and
detecting, by means of a first quality sensor assembly in the emptying and monitoring device, of at least one quality parameter of the fluid drained from the engine of the aircraft having been admitted through the first intake passage.

11. The emptying and monitoring method according to claim 10 , wherein the connecting step is accomplished automatically.

12. The emptying and monitoring method according to claim 10 , wherein the articulated pole is also telescopic.

13. The emptying and monitoring method according to claim 10 , further comprising a step of moving the emptying and monitoring device, on-board an airport service vehicle, to the aircraft.

14. The emptying and monitoring method according to claim 13 , comprising autonomous control of the airport service vehicle during the movement step.
