Multi-hole pressure probe and use of such a probe

A multi-hole pressure probe for measuring the pressure, flow speed, and/or flow direction of a fluid, the multi-hole pressure probe extending along a longitudinal axis and comprising:

• a probe tip provided with a main channel inlet port facing in an upstream direction along the longitudinal axis, the probe tip having an outer probe tip surface adjacent to said main channel inlet port;
• a main channel connected to said main channel inlet port, the main channel extending from the main channel inlet port in a downstream direction, opposite to the upstream direction, and being defined by a main channel inner wall;
• a stagnation pressure probing port arranged within the main channel, downstream of the main channel inlet port, and facing the main channel inlet port in the upstream direction, the stagnation pressure probing port being connected to a stagnation pressure probing channel;
• a set of side port arrangements in the outer probe tip surface, each of said side port arrangements being connected to a respective side port probing channel;
• the main channel inner wall has a convergent section extending in the downstream direction from the main channel inlet port and a divergent section downstream of the convergent section;
• at least one static pressure probing port connected to a static pressure probing channel, wherein said at least one static pressure probing port is arranged in the main channel between the main channel inlet port and the main channel outlet, for probing the static pressure in the main channel;
• characterized in that the at least one static pressure probing port is arranged in the divergent section of the main channel.
