Abstract: The invention concerns a device for measuring at least one physical parameter of a fluid flow, in particular the total air temperature, comprising: a profiled body (2) of elongate shape along a longitudinal axis (L) and having at least two walls arranged contiguous to each other at an acute angle to form a wedge-shaped portion (7), said wedge-shaped portion (7) extending in a direction parallel to the longitudinal axis (L) of the profiled body (2); at least one sensing element (4) for measuring the physical parameter of the fluid flow, said sensing element (4) being positioned in a window (3) formed through the profiled body (2), characterized in that each of the walls (71; 72) forming the wedge-shaped portion (7) comprises at least one notch forming a deflector angle relative to said wall (71; 72) so as to weaken the formation of ice on the wedge-shaped portion (7).

Abstract: A sensor for measuring a physical parameter of a fluid, in particular for measuring total air temperature, the sensor comprising: a fluid intake (1) fitted to a streamlined body (2); a duct provided in said streamlined body (2) to enable fluid flow, said duct communicating with said fluid intake; and a sensing element disposed inside said duct. The sensor is characterized in that it includes elements that give it improved measurement performance. In particular, the proposed air intake presents an inlet section which extends so as to define a sliding surface suitable for eliminating ice. The invention also provides an improved system for sucking in the boundary layer by using slots, and it also provides a ceramic sensing element that provides better thermal decoupling relative to the de-iced body.

Abstract: The invention proposes an ice detector for detecting ice accretion on the surface of a structure subject to icing, said ice detector comprising a sensing element protruding into the airflow and supported relatively to a surface of said object by a strut upon which it is mounted, characterized in that said sensing element has an evolutionary profile along the longitudinal axis adapted to the spectral distribution of the icing conditions. Said sensing element is adapted to the profile of ice distribution on the aircraft and allows detection on a large spectrum of droplet sizes.
