Abstract
A system for measuring turbulence of a flow of a turbine engine, notably of a turbine engine compressor includes a first housing with a first pressure sensor and a first inlet, a second housing with a second pressure sensor and a second inlet inclined relative to the first inlet, and a temperature sensor. The system is configured to calculate at least two orientation components of the velocity of the flow on the basis of the pressure sensors and the temperature sensor. The inlets are disposed at the vane foot, on the leading edge at the level of an internal shell.
Claims18
Compressor of a turbine engine, the compressor comprising:
- an upstream air intake for an air flow;
- an annular row of vanes;
- and
- a system for measuring turbulences in said air flow, the turbulence measuring system comprising:
- a first housing receiving a first pressure sensor and a first inlet,
- a second housing receiving a second pressure sensor and a second inlet inclined relative to the first inlet;
- and
- a temperature sensor,
- wherein the first and second inlet are received in the same vane of the annular row of vane, said vane having a radial height, and the first and second inlet being positioned within at most:
- 30%, or 10%, or 5% of the radial height of said vane;
- the system being configured to continuously calculate at least two orientation components of the velocity of the air flow on the basis of the pressure sensors and the temperature sensor.
