Abstract: The invention relates to a heat exchanger (20) plate (1, 2a) intended to delimit at least one channel (30, 30a, 30b) for circulation of a fluid, the circulation plate (1) being provided with a bottom (3) and a raised rim (5, 5a-5h) that surrounds the bottom (3), the circulation plate (1) comprising at least one opening (7, 7a-7d) through which a fluid can enter the channel (30, 30a, 30b), characterized in that the opening (7, 7a-7d) is delimited by at least one at least partially rectilinear edge (9a). Application to the field of heat exchanges.

Abstract: An assembly for a turbine engine, the assembly including a casing and an impeller rotatably movable inside the casing, the impeller including at least one blade having a tip edge opposite the casing, wherein the tip edge includes a magnet and wherein the casing includes an electrical conductor suitable for generating between the terminals thereof an electric voltage induced by the magnet of the tip edge opposite same and representing vibrations sustained by the tip edge of the blade when the impeller is rotated.

Abstract: A turbine engine assembly includes a housing and a bladed wheel rotatable within the housing. The bladed wheel includes a blade including a head opposite the housing. The head includes a magnet and the housing includes first and second electrical conductors. Each electrical conductor generates, across terminals thereof, an electrical voltage induced by the magnet of the head opposite the housing and that represents vibrations of the head of the blade when the bladed wheel is rotated. The first electrical conductor includes a first central portion extending around the rotational axis of the bladed wheel and includes two mutually facing ends, and the second electrical conductor includes a second central portion passing through a space left by the first central portion between the two ends thereof. The arrangement of the electrical conductors makes it possible to obtain two voltages for determining an axial vibration speed at the tip.
