摘要： A variable pitch fan for a propulsion device is provided. The variable pitch fan includes a plurality of fan blades 40 coupled to a disk 42 and a rotatable front hub 52 covering the disk. Each fan blade 40 is rotatable about a pitch axis (P) to vary a pitch of the fan blade 40. The pitch is variable within a pitch range that is at least about 80° to about 130°. Each fan blade 40 extends radially outward from the disk 42 along a span (S) from a root 102 to a tip (104). A portion of the span (S) adjacent the root 102 defines a root span region (S R ), a portion of the span (S) adjacent the tip 104 defines a tip span region (S T ). A solidity of the variable pitch fan is at least 1.0 in the root span region (S R ).

摘要： An apparatus, for example for a pitch change mechanism, includes a cylinder having a magnetic portion defining an annular array of features extending parallel to the longitudinal axis of the cylinder, the cylinder rotating in use and able to translate longitudinally. There is a sensing arrangement including a stationary magnetised core and two coils connected in series and wound around the core. In use, the cylinder rotates and current is induced in the coils. Monitoring equipment is arranged to calculate rotational speed of the cylinder from the frequency of the current and to calculate longitudinal position from the relative amplitude of the current in each coil. Also a method.

摘要： The invention relates to a device for controlling the orientation of fan blades of a turboprop engine comprising at least one set (24a, 24b) of adjustable-orientation fan blades rotatably secured to a rotary ring (28a, 28b) mechanically linked to a turbine rotor (22a, 22b). Each blade of the set is coupled to a blade shank support pivotably mounted to the rotary ring by means of a bevel gear formed by a first toothed wheel solidly connected to the blade shank support and a second toothed wheel (50) solidly connected to the rotary ring and bearing a counterweight (54) located eccentrically to the axis of rotation thereof. The invention also includes a cylinder (30a, 30b), rotatably connected to the turbine rotor and including a rod (32a, 32b) that is connected to each counterweight (54) by means of a linking arm, which cylinder can be used for the angular and synchronised movement of the set of counterweights around the axis of rotation of the respective toothed wheel thereof.
