### 10.2.4. Auxiliary Views

The Auxiliary View provides a variety of formats for reviewing the blade design. It is used for data display only.

The following topics are discussed:

- Blade-to-Blade View
- Blade Lean Graph
- Curvature View
- Meridional Curvature View

#### 10.2.4.1. Blade-to-Blade View

When using Camberline/Thickness design mode (enabled via the Blade Design Mode setting of the blade object), the blade-to-blade view is available. This view shows the blade profile for the selected CamThkDef sub-feature in either of the following coordinate systems:

- M-Prime vs. Theta

- M vs. R*Theta

Note: Profiles are shown for all blades in the selected blade row.

To show the blade-to-blade view:

1. Select the CamThkDef sub-feature for which you want the blade-to-blade view. (The CamThkDef sub-feature you select must be a sub-feature of a Blade.)

2. If you do not see the Auxiliary view, click Show/Hide Auxiliary Pane .

3. If the Auxiliary view shows a plot other than blade-to-blade, right-click in the Auxiliary view and select Blade-to-blade.

Within the blade-to-blade view, you can use the context menu to:

- Change the type of plot.

- Toggle the coordinate system between “M-Prime vs. Theta” and “M vs. R*Theta”.

- Zoom to fit the view

#### 10.2.4.2. Blade Lean Graph

When using Camberline/Thickness design mode (enabled via the Blade Design Mode setting of the blade object), the blade lean graph is available. This graph shows a plot of the blade lean angle versus meridional coordinate (%M). The blade lean angle is essentially the angle between a constant-theta line and a straight line connecting the hub and shroud camberlines, as viewed in a plane of constant meridional coordinate.

To show the blade lean graph:

1. Select the blade (or any CamThkDef sub-feature of it) for which you want the blade lean graph.

2. If you do not see the Auxiliary view, click Show/Hide Auxiliary Pane .

3. If the Auxiliary view shows a plot other than blade lean angle, right-click in the Auxiliary view and select Blade Lean Angle.

Within the blade lean graph, you can use the context menu to:

- Change the type of plot.

- Zoom to fit the view

#### 10.2.4.3. Curvature View

When using Airfoil design mode (enabled via the Blade Design Mode setting of the blade object), the Curvature view is available. This view shows a plot of either the curvature or the radius of curvature of the outline of the airfoil section versus percent arc length. Curvature is evaluated in the applicable layer (the layer containing the blade section). Arc length is measured along the outline of the airfoil section, starting at the major axis of the leading edge ellipse and ending at the major axis of the trailing edge ellipse.

To show the Curvature view:

1. Select the any Blade Section sub-feature for which you want the Curvature view.

2. If you do not see the Curvature view at this point, click Show/Hide Auxiliary Pane .

Within the Curvature view, you can use the context menu to:

- Toggle display of the curvature/radius of curvature data for the high-theta side only.

- Toggle display of the curvature/radius of curvature data for the low-theta side only.

- Toggle between viewing curvature or radius of curvature.

- Zoom to fit the view.

#### 10.2.4.4. Meridional Curvature View

This view shows a plot of meridional curvature of the hub/shroud versus either meridional, or normalized meridional, coordinate. Meridional curvature is computed as the inverse of the radius of curvature in the axial-radial plane. For a plot that uses normalized meridional coordinate, normalization is carried out such that the coordinate ranges from 0 to 100 over the plot. The portions of the hub and shroud curves that are plotted depend on the selected feature: a FlowPath feature or a Blade feature.

To show the Meridional Curvature view:

1. Select either a FlowPath feature or a Blade feature.

2. If you do not see the Auxiliary view, click Show/Hide Auxiliary Pane .

3. If the Auxiliary view shows a plot other than meridional curvature, right-click in the Auxiliary view and select Meridional Curvature.

Within the Meridional Curvature view, you can use the context menu to:

- Change the type of plot.

- Toggle display of the hub curvature data.

- Toggle display of the shroud curvature data.

- Change the X-Axis Scale between meridional coordinate and normalized meridional coordinate.

- Zoom to fit the view.

When you click a line in a plot, the details view shows the following coordinates of the point you clicked:

- Z (axial coordinate)

- R (radial coordinate)

- M (meridional coordinate)

- % M (normalized meridional coordinate)

- Meridional curvature
