摘要： A turbine blade for a wind turbine, the turbine blade has a blowing and suction provision in form of a plurality of arrays of blowing and suction holes defined on a curved suction surface of the turbine blade. An apparatus for turbine blade testing includes the turbine blade. The apparatus also includes a wind tunnel, a blowing source, and a suction source. The wind tunnel includes a wind channel having first and second end plates for mounting the turbine blade. A method of testing air flow in a turbine blade involves changing holes used for blowing and suction and determining a momentum coefficient for those various holes; and varying angle of attack with measurement of lift/drag ratio.

摘要： An airfoil body may include a plurality of tubercles along a leading edge of the airfoil body and a plurality of crenulations along a trailing edge of the airfoil body, wherein at least one of a position, a size, and a shape of the plurality of tubercles and the plurality of crenulations varies in a non-periodic fashion. The non-periodic fashion may be according to a Fibonacci function and may mimic the configuration of a pectoral fin of a humpback whale. The tubercles and crenulations may be defined with respect to a pivot point. The spanwise profile, including the max chord trailing edge curvature, may closely follow divine spirals and related Fibonacci proportions. The spanwise chord thickness may vary in a nonlinear pattern. Related methods are also described.

摘要： A transpiration air cooled combustor assembly for a gas turbine engine includes an annular liner of laminated metal with an inner sheet and an outer sheet having a plurality of mechanically formed holes therein on either side of a mechanically pressed waffle patterned core sheet with offset depressings and dimples on either face thereof; the dimples have raised lands bonded to the inner and outer sheets; small cross passages are drilled in the core sheet so that the margins of the cross passages are located in spaced relationship to the land surfaces thereby to prevent burr formation disruption of the bond joints; the core sheet has a total metal mass equivalent to the orginal metal mass prior to press displacement of metal to form the depressions and dimples therein except for the metal removed by formation of the cross passages which communicate offset depressions on opposite sides of the core sheet to form a tortuous intercommunicating flow path through said annular liner between holes in the inner and outer sheets for flow of coolant therethrough.

摘要： A transpiration air cooled combustor for use with gas turbine engines includes an annular wall of laminated readily deformable metal having plural layers of diffusion bonded material in a combustor wall with inner and outer surfaces; each of the inner and outer surfaces has pores formed therein by a process such as photoetching to provide numerous inlets on the outer surface of the combustor wall for directing cooling air through the wall to a plurality of outlets in the inner surface for flow of cooling air across the inner surface; and wherein at least two surfaces of the layers includes a plurality of continuously formed curvilinear grooves communicating with the inlets and outlets and also intersecting one another to form crossover passages between the grooves for communicating the inlets and outlets and wherein the curved grooves serve to produce minimal surface distortion and stretch marks across curvilinear portions of the outer wall portion of the combustor assembly to prevent formation tears therein whereby the combustor construction has a uniform flow of coolant from the exterior thereof to the interior thereof throughout the full surface extent of the wall of the combustor.
