Embodiment Construction

[0056] In the following description, the axial direction corresponds to a direction extending along the rotational axis of the turbomachine. The radial direction is perpendicular to the axis of rotation. Upstream and downstream refer to the main flow direction of the fluid in the turbine. The height and vertical aspect of the cabinets are relative to the normal assembly orientation.

[0057] figure 1 is a simplified schematic diagram of a shaft turbine. In this particular case, it is a twin-flow turbojet engine. The turbojet engine 2 has a first compression stage known as a low-pressure compressor 4 , a second compression stage known as a high-pressure compressor 6 , a combustion chamber 8 and one or more turbine stages 10 . In operation, the mechanical power of the turbine 10 , transmitted via the shaft to the rotor 12 , moves the two compressors 4 and 6 . The latter two have rows of rotor blades associated with rows of stator blades. Thus, the rotation of the rotor abo...

Abstract

The present invention relates to an oil tank 30 fitted to a turbomachine, for example an aeroplane turbo-jet engine. The tank 30 includes an inner chamber 36 containing the oil of the turbomachine, awall 42 with an inner surface 40 surrounding the inner chamber 36, and a capacitive device for measuring the oil level. The device includes at least one electrode 38 and potentially two parallel electrodes 38 forming the inner surface. These electrodes 38 are immersed in the oil to measure the oil level by measuring capacitance. The present invention also provides a method for manufacturing the tank 3 in which the electrodes are printed on the wall 42.

Description

technical field [0001] The present invention relates to measuring the level of liquid in the tank of a turbomachine. The invention also proposes a shaft turbine comprising a housing, in particular an aircraft turbojet or aviation turboprop. The invention also proposes a method for manufacturing the box. Background technique [0002] Turbojet engines use oil in operation. This fluid is used for lubrication, but also for heat exchange. Heat exchange means cooling certain components and heating areas that experience freezing. Additionally, oil may be pressurized to actuate hydraulic cylinders. [0003] This fluid plays a critical role and must therefore be stored correctly and the amount of oil available in a turbojet engine must be accurately measured. To meet the latter requirement, the oil tank usually has a window for displaying the level of the stored fluid. The window is a transparent glass part so that the inside of the box can be inspected by simple visual inspect...
