## Title
LP turbine blade airfoil profile

## Abstract

A single stage low pressure turbine blade includes an airfoil having a profile substantially in accordance with at least an intermediate portion of the Cartesian coordinate values of X, Y and Z set forth in Table 2. The X and Y values are distances, which when smoothly connected by an appropriate continuing curve, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape.

## Background
TECHNICAL FIELD
The invention relates generally to a blade airfoil for a gas turbine engine and, more particularly, to an airfoil profile suited for a single-stage low-pressure turbine (LPT) blade of a power auxiliary unit (APU).
BACKGROUND OF THE ART
Where a blade airfoil is part of a single stage turbine driving a fan or output shaft (i.e. is a low pressure or LP turbine), as opposed to being part of multiple stage LP turbine, the requirements for such an airfoil design are significantly more stringent, as the fan/output shaft relies solely on this airfoil to deliver work, as opposed to work being spread over several turbine stages. Over and above this, the airfoil is subject to flow regimes which lend themselves easily to flow separation. Such a situation tends to limit the amount of work transferred to the fan/output shaft, and hence the total thrust (or power) capability of the engine, as follows. In order to achieve the work requirement out of a single stage LP turbine, it is desirable to flare the gaspath outward as quickly as possible upon leaving the high pressure (HP) turbine located upstream. This creates a situation where the gaspath entering the LP turbine is on a steep outward flaring angle, and the LP turbine must quickly redirect this flow into a more axial direction without any flow separation. Therefore, improvements in airfoil design are sought.
SUMMARY OF THE INVENTION
It is therefore an object of this invention to provide an improved airfoil suitable for use in a single stage turbine of a high power APU.
In one aspect, the present invention a turbine blade for a gas turbine engine, comprising an airfoil having an intermediate portion defined by a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of Sections 3 to 9 set forth in Table 2, wherein the point of origin of the orthogonally related axes X, Y and Z is located at an intersection of a centerline of the gas turbine engine and a stacking line of the turbine blade, the Z values are radial distances measured along the stacking line, the X and Y are coordinate values defining the profile at each distance Z.
In another aspect, the present invention provides a turbine blade for a gas turbine engine, the turbine blade having an intermediate airfoil portion at least partly defined by a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of Sections 3 to 9 set forth in Table 2, wherein the point of origin of the orthogonally related axes X, Y and Z is located at an intersection of a centerline of the gas turbine engine and a stacking line of the turbine blade in the engine, the Z values are radial distances measured along the stacking line of the airfoil, the X and Y are coordinate values defining the profile at each distance Z, and wherein the X and Y values are scalable as a function of the same constant or number.
In another aspect, the present invention provides a turbine rotor for a gas turbine engine, comprising a plurality of blades extending from a rotor disc, each blade including an airfoil having an intermediate portion defined by a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of Sections 3 to 9 set forth in Table 2, wherein the point of origin of the orthogonally related axes X, Y and Z is located at an intersection of a centerline of the gas turbine engine and a stacking line of the blades, the Z values are radial distances measured along the stacking line, the X and Y are coordinate values defining the profile at each distance Z.
In accordance with a still further general aspect of the present invention, there is provided a low pressure blade adapted to be mounted in a gaspath comprising a stacking line, the stacking line defining the position of the blade in the gaspath, an airfoil having a surface lying substantially on the points of Table 2, the airfoil extending between a platform and a shrouded tip, the platform being generally defined by an inner gaspath wall of Table 1, and wherein the shrouded tip is defined as a function of an outer gaspath wall of Table 1 in the vicinity of said stacking line.
According to one aspect, the airfoil exit aerodynamic profile is optimized to provide a balanced single stage LPT blade with de-swirl cascade downstream. According to a further general aspect, the profile is designed to reduce the radial static pressure distribution in the blade channel so as to decrease secondary flow losses.
Further details of these and other aspects of the present invention will be apparent from the detailed description and figures included below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates a gas turbine engine 10 of a type preferably provided for use as a high power APU, generally comprising in serial flow communication a fan 12 through which ambient air is propelled, a multistage compressor 14 for pressurizing the air, a combustor 16 in which the compressed air is mixed with fuel and ignited for generating an annular stream of hot combustion gases, and a turbine section 18 for extracting energy from the combustion gases to drive the fan, the compressor, and produce thrust.
The gas turbine engine 10 further includes a turbine exhaust duct 20 which is exemplified as including an annular core portion 22 and an annular outer portion 24 and a plurality of struts 26 circumferentially spaced apart, and radially extending between the inner and outer portions 22, 24.
FIG. 2 illustrates a portion of an annular hot gaspath, indicated by arrows 27 and defined by annular inner and outer walls 28 and 30 respectively, for directing the stream of hot combustion gases axially in an annular flow. The profile of the inner and outer walls 28 and 30 of the annular gaspath, at “cold”(i.e. non-operating) conditions, is defined by the Cartesian coordinate values given in Table 1 below. More particularly, the inner and outer gaspath walls 28 and 30 are defined with respect to mutually orthogonal x and z axes, as shown in FIG. 2. The x axis corresponds to the engine turbine rotor centerline 29. The radial distance of the inner and outer walls 28 and 30 from the engine turbine rotor centerline and, thus, from the x-axis at specific axial locations is measured along the z axis. The z values provide the inner and outer radius of the gas path at various axial locations therealong. The x and z coordinate values in Table 1 are distances given in inches from the point of origin O (see FIG. 2). It is understood that other units of dimensions may be used. A manufacturing tolerance of ±0.005′′ is applicable to the X and Z coordinate values between the leading edge and the trailing edge of the low pressure turbine blades.
The turbine section 18 has a high pressure turbine (HPT) stage located downstream of the combustor 16 and a low pressure turbine (LPT) stage located further downstream in the gaspath 27. The turbine exhaust duct 20 is shown downstream from the LPT stage. The LPT has a single stage.
Referring to FIG. 2, the HPT stage is preferably transonic and comprises a stator assembly 32 and a rotor assembly 36 having a plurality of circumferentially spaced vanes 40a and blades 42a respectively. Likewise, the LPT stage comprises a stator assembly 34 and a rotor assembly 38 having a plurality of circumferentially spaced vanes 40b and blades 42b. The vanes 40a,b and blades 42a,b are mounted in position along respective stacking lines 44-50, as identified in FIG. 2. The stacking lines 44-50 extend in the radial direction along the z axis at different axial locations. The stacking lines 44-50 define the axial location where the blades and vanes of each stage are mounted in the engine 10. More specifically, stacking line 44 located at x=0 corresponds to the HPT vane 40a. Stacking line 46 located at x=1.7950 corresponds to the HPT blade 42a. Stacking line 48 located at x=4.5460 corresponds to the LPT vane 40b. Stacking line 50 located at x=5.9910 corresponds to the LPT blade 42b. Furthermore, FIG. 2 also illustrates stacking lines 52 and 53 corresponding respectively to the thin and the thick turbine exhaust duct struts 26a and 26b. Stacking lines 52 and 53 are respectively located at x=11.5305 and 11.5395.

More specifically, the rotor assemblies 36, 38 each include a disc drivingly mounted to respective engine shafts 39 and 41 (see FIG. 1). Each disc carries at its periphery the plurality of circumferentially distributed blades 42 that extend radially outwardly into the gaspath 27. The HPT includes 14 HP vanes and 65 HP blades, the LPT include 38 LP vanes and 59 LP blades, and there are 5 thin and 3 thick airfoils in the turbine exhaust case.
FIG. 3 shows an example of a blade 42b of the LPT stage. It can be seen that each blade 42b has an airfoil 56 having a leading edge 58, a trailing edge 60 and a shrouded tip 62. The airfoil 56 extends from a platform 64 provided at the upper end of a root portion 66. The root portion 66 is adapted to be captively received in a complementary blade attachment slot (not shown) defined in the outer periphery of the disc such that it resists axial and centrifugal dislodgement of the blade 42.
The novel airfoil shape of each LPT stage blade 42b is defined by a set of X-Y-Z points in space. This set of points represents a novel and unique solution to the target design criteria discussed above, and is well-adapted for use in a single-stage LPT design. The set of points are defined in a Cartesian coordinate system which has mutually orthogonal X, Y and Z axes. The X axis extends axially along the turbine rotor centerline 29, i.e., the rotary axis. The positive X direction is axially towards the aft of the turbine engine 10. The Z axis extends along the LPT blade stacking line 50 of each respective blade 42b in a generally radial direction and intersects the X axis at the center of rotation of the rotor assembly 38. The positive Z direction is radially outwardly toward the blade tip 62. The Y axis extends tangentially with the positive Y direction being in the direction of rotation of the rotor assembly 38. Therefore, the origin of the X, Y and Z axes is defined at the point of intersection of all three orthogonally-related axes: that is the point (0,0,0) at the intersection of the center of rotation of the turbine engine 10 and the staking line 50.
In a particular embodiment of the LPT stage, the set of points which define the HPT stage blade airfoil profile relative to the axis of rotation of the turbine engine 10 and the stacking line thereof are set out in Table 2 below as X, Y and Z Cartesian coordinate values. Particularly, the blade airfoil profile is defined by profile sections 70 at various locations along its height, the locations represented by Z values. It should be understood that the Z values do not represent an actual radial height along the airfoil 56, but are defined with respect to the engine centerline. For example, if the blades 42b are mounted about the rotor assembly 38 at an angle with respect to the radial direction, then the Z values are not a true representation of the height of the airfoils of the blades 42b. Furthermore, it is to be appreciated that, with respect to Table 2, Z values are not actually radial heights, per se, from the centerline but rather a height from a plane through the centerline—i.e, the sections in Table 2 are planar. The coordinate values are set forth in inches in Table 2 although other units of dimensions may be used when the values are appropriately converted.
Thus, at each Z distance, the X and Y coordinate values of the desired profile section 70 are defined at selected locations in a Z direction normal to the X, Y plane. The X and Y coordinates are given in distance dimensions, e.g., units of inches, and are joined smoothly, using appropriate curve-fitting techniques, at each Z location to form a continuous airfoil cross-section. The blade airfoil profiles of the various surface locations between the distances Z are determined by smoothly connecting the adjacent profile sections 70 to one another to form the airfoil profile.
The coordinate values listed in Table 2 below represent the desired airfoil profiles in a “cold” (i.e. non-operating) condition. However, the manufactured airfoil surface profile will be slightly different, as a result of manufacturing tolerances. The coordinate values listed in Table 2 below are for an uncoated airfoil. According to an embodiment of the present invention, the finished LPT blades remain uncoated.
The Table 2 values are generated and shown to three decimal places for determining the profile of the LPT stage blade airfoil. However, as mentioned above, there are manufacturing tolerance issues to be addressed and, accordingly, the values for the profile given in Table 2 are for a theoretical airfoil, to which a ±0.003 inches manufacturing tolerance is additive to the X and Y values given in Table 2 below. The LPT stage blade airfoil design functions well within this preferred range of variation. The cold or room temperature profile is given by the X, Y and Z coordinates for manufacturing purposes. It is understood that the airfoil may deform, within acceptable limits, once entering service.
The coordinate values given in Table 2 below provide the preferred nominal LPT stage blade airfoil profile.

It is understood that the finished LPT blade 42b does not necessarily include all the sections define in Table 2. The tip 62 and the airfoil portion proximal the platform 64 may not be defined by a profile section 70. For example, in a particular embodiment in which the tip 62 is angled, multiple tip 62 cross-sections would not be defined by a profile section 70. Notably, it should be considered that the airfoil profile proximal to the platform 64 may vary due to several imposed constraints. However, the LPT blade 42b has an intermediate airfoil portion 68 defined between the platform 64 and the tip 62 thereof and which has a profile defined on the basis of at least the intermediate sections of the various blade profile sections 70 defined in Table 2.
It should be appreciated that the intermediate airfoil portion 68 of the LPT stage blade 42b is defined between the inner and outer gaspath walls 28 and 30, wall 28 being partially defined by the LPT blade platform. More specifically, the Z values defining the intermediate airfoil portion 68 in the region of the stacking line 50 fall within the range of Z=4.223 and Z=6.663 which are the z values of the inner and outer walls 28 and 30 of the gaspath at the stacking line 50 (see Table 1). Therefore, the airfoil profile physically appearing on LPT blade 42b includes Sections 3 to 9 of Table 2. Sections 1, 2, 10 and 11 are completely located outside of the boundaries set by the inner and annular outer gaspath walls 28 and 30, but are provided, in part, to fully define the airfoil surface and, in part, to improve curve-fitting of the airfoil at its radially distal portions. The skilled reader will appreciate that a suitable fillet radius is to be applied between the LPT blade platform and the airfoil portion, and that a suitable tip shroud and tip clearance is to be provided.
The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made to the embodiments described without department from the scope of the invention disclosed. For example, the airfoil and/or gaspath definitions of Tables 1 and 2 may be scaled geometrically, while maintaining the same proportional relationship and airfoil shape, for application to gas turbine engine of other sizes. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in light of a review of this disclosure, and such modifications are intended to fall within the appended claims.
