摘要： Provided is a propeller fan (1) capable of achieving lower noise by suppressing a leakage flow of an air current, and also achieving higher efficiency by increasing the rate of air to be blown. The propeller fan (1) includes a boss (2) including a rotation axis (O), a plurality of blades (3) formed on an outer periphery of the boss, and a bellmouth (9) arranged so as to surround the plurality of blades at a trailing edge side of each of the blades. Each blade has a bending portion (13) that bulges toward an upstream side of the air current in a cross-sectional shape in a radial direction. In a blade cross-sectional view, assuming that a tangent at an end of the outer periphery is defined as LQ, an imaginary line orthogonal to the rotation axis (O) is defined as LO, an angle formed by the tangent (LQ) and the imaginary line (LO) is defined as an outer peripheral end tangent angle (¸), and a position at which an imaginary plane including a position of an intake-side end portion of the bellmouth and a peripheral edge of the blade cross each other is defined as an overlap starting point, the outer peripheral end tangent angle (¸) on a trailing edge portion side with respect to a blade cross section including the overlap starting point is set to be smaller than the outer peripheral end tangent angle (¸) on a leading edge portion side with respect to the blade cross section including the overlap starting point.

摘要： An airfoil cooling system (54) for a gas turbine engine (10) is disclosed. The airfoil cooling system (54) may be formed from at least a first cooling fluid supply system (56), and a second cooling fluid supply system (58). The first cooling fluid supply system (56) may be configured to supply cooling fluids at a first pressure to one or more airfoils of a first row (68) of airfoils, and the second cooling fluid supply system (58) may be configured to supply cooling fluids at a second pressure to the one or more airfoils of the first row (68) of airfoils. Additionally, the second pressure may be lower than the first pressure. As such, each of the one or more airfoils may be cooled by cooling fluids at two different pressures. In particular embodiments, this may allow the airfoils to be cooled, while lowering the cost to the turbine engine (10) for providing such cooling.

摘要： Of plural vanes (23) provided between a shroud (22) and a main plate (21), a shape on a side of a negative-pressure surface (K) in a section cut in parallel with a surface direction of the main plate (21) includes a recess portion (30) and a curved portion (35). The recess portion (30) is recessed toward a side of a positive-pressure surface (D) except for a leading edge portion (Ef), which is an inner circumferential side. The curved portion (35) is continuously provided from the recess portion (30) to a leading edge portion, and is expanded toward the negative-pressure surface side. A maximum thickness position (Q) of the curved portion (35) is set at a position in a range of 10% to 30% of a vane chord length from a front end of the leading edge portion, whereby airflow separation is inhibited to achieve an increased flow volume and noise reduction.
