Abstract
The disclosed technology concerns an aircraft turbomachine part comprising a part body drilled with at least one cavity open to the outside and at least one conduit joining the cavity on the one hand and leading to the outside on the other hand. Each cavity receives a pressure sensor, and the conduit corresponds to the cavity guides the cables connected to the sensor to the outside of the part body. The part is an aircraft turbomachine vane.
Claims15
A part for an aircraft turbomachine comprising a part body, a first pressure sensor and a first cable mechanically and electrically connected to the first pressure sensor, the part body comprising:
- a first cavity leading to the outside of the part body through a first opening, and
- a first conduit leading to the first cavity on the one hand and to the outside of the part body on the other hand,
- the first sensor being at least partially housed in the first cavity and the first cable being at least partially housed in the first conduit,
- the first sensor comprising a first membrane, the first pressor sensor being arranged so that at least a portion of the first membrane is part of the outer surface of the first pressure sensor,
- the part forming a vane of the aircraft turbomachine in which the first cavity is located in a leading edge of the vane;
- wherein the part further comprises a second pressure sensor and a third cable mechanically and electrically connected to the second pressure sensor, the part body comprising:
- a second cavity leading to the outside of the part body through a second opening, and
- a second conduit leading to the second cavity on the one hand and to the first conduit on the other hand,
- the second pressure sensor being at least partially housed in the second cavity and the third cable being partially housed in the second conduit and partially housed in a portion of the first conduit, and
- the second pressure sensor comprising a second membrane, the second sensor being arranged so that at least a portion of the second membrane is part of the outer surface of the second pressure sensor.
