    摘要: A fan outlet guide vane for a gas turbine engine comprises a generally radially-extending internal structural member and at least one surface member securable in use to the internal structural member so as to define an aerofoil. The gas turbine engine includes an annular first structure and an annular second structure, the second structure being radially outward of the first structure so as to define a duct between them, and in use the internal structural member of the vane is secured between the first structure and the second structure. In a preferred embodiment, the surface member or surface members are secured only to the internal structural member, and not to the first or second structures.

    摘要: A gas turbine engine (20) includes a fan (42), a turbine section (28) having a fan drive turbine rotor (46), and a compressor rotor (44). A gear reduction (48) effects a reduction in a speed of the fan (42) relative to an input speed from the fan drive turbine rotor (46). The compressor rotor (44) has a number of compressor blades in at least half of a plurality of blade rows of the compressor rotor (44). The blades are configured to operate at least some of the time at a rotational speed. The number of compressor blades in the at least half of the blade rows and the rotational speed is such that the following formula holds true for each row of the at least half of the blade rows of the compressor rotor (44): (the number of blades × the rotational speed) / 60s ≥ about 5500 Hz.

    摘要: The invention relates to a compressor for a turbine engine, comprising: a casing, at least one compressor stage formed by an impeller having stationary blades and an impeller having moving blades (1) positioned downstream of the stationary blade impeller, and cavities (5) in the thickness of the casing that are disposed along a circumference of said casing (4) opposite the moving blades (1). The cavities, which are elongate and extend along a main direction of orientation, are closed upstream and downstream by upstream and downstream faces respectively, and an upstream border (7) and a downstream border (6) are formed at the intersections between same and the casing. The cavities are offset in relation to the moving blades (1) such as to overlap the moving blade impeller in the upstream portion, thereby covering the upstream end thereof. The casing is characterised in that the downstream border (6) of the cavities (5) is oriented parallel to the chord at the head of the moving blade (1).
