Abstract

A device for checking at least one pressurized testing tool for a fluid circuit of an aircraft includes at least one tank that includes at least one connection to connect a pressurized gas supply and at least one connection system arranged to connect at least one pressurized testing tool. This device makes it possible to perform preventive checks on pressurized testing tools without having to immobilize an aeroplane on an assembly line.

Claims

1. A device for checking at least one pressurized testing tool for a fluid circuit of an aircraft, the device comprising:

at least one tank including at least one connection to connect a pressurized gas supply and at least one connection system arranged to connect at least one pressurized testing tool.

2. The device according to claim 1, wherein the at least one tank is a vat with a capacity equal to or greater than 200 L.

3. The device according to claim 2, wherein the connection system includes at least one opening enabling communication between the inside and the outside of the vat and a joining system configured to hold a closing element in a position in which the closing element closes the opening.

4. The device according to claim 3, further comprising an interface including a wall traversed by a window the shape of which is adapted to the shape of the testing tool to be checked, said wall having an internal face with a peripheral bearing surface configured to cooperate with a bearing surface of the opening.

5. The device according to claim 4, wherein the connection system includes:

an outer chamber delimited by a back and a peripheral wall having an edge corresponding to the bearing surface of the opening, and

a conduit for communicating the outer chamber with the inside of the vat.

6. The device according to claim 3, further comprising centering means to facilitate the positioning of an interface or of a door in relation to the opening.

7. The device according to claim 3, further comprising a false door for closing the opening.

8. The device according to claim 2, further comprising at least a second vat, each of the vats having a connection and a connection pipe configured to link the two connections and to enable communication between the at least two vats.

9. The device according to claim 1, wherein the at least one tank is a line.

10. The device according to claim 9, wherein the internal diameter of the line is between 40 and 100 mm and/or the length of same is between 3 and 10 m.

11. The device according to claim 9, wherein the line includes a reducing valve linked to the connection for connecting a pressurized gas supply.

12. The device according to claim 1, further comprising a moveable chassis carrying the at least one tank.

13. The device according to claim 12, wherein the moveable chassis includes a frame moveable between a blocking position in which at least one portion of the moveable frame is arranged opposite the connection system configured to connect at least one pressurized testing tool and a released position in which the moveable frame releases said connection system and enables placement of an interface, a false door, a pressurized testing tool, or any other closing element.

14. The device according to the claim 13, wherein the moveable frame includes two uprights each having an aperture in which is seated a pivot axis carried by a static frame at least one of the uprights having a hook configured to cooperate with a pin rigidly connected to a static frame in the blocking position.

15. The Device according to claim 12, wherein the moveable chassis includes a moveable shelf positioned beneath a line acting as a tank.

16. The device according to claim 12, wherein the moveable chassis includes a structure surrounding the at least one tank in the form of a vat, a portion of which forms a supporting element to which a tank in the form of a line is attached.

17. The device according to claim 16, wherein the supporting element is arranged vertically so that the line is arranged in a vertical plane.

18. The device according to claim 16, wherein the line follows an S-shaped path.
