[FAQ]

The “Theta with LE/TE Beta” option can be used for any defining layer, but it is only shown if the Theta definition is a Bezier curve. If it is not set to Bezier , you must first convert the curve to a Bezier, selecting the number of Bezier points to use. Once you do that, the “Theta with LE/TE Beta” will be available for selection. This is noted in the BladeEditor Help, as follows: If the Angle Definition Type is set to Theta with LE/TE Beta, then you can control the theta distribution as well as specify the leading and trailing edge Beta values. This type is not offered until you have generated the camberline with: •Angle Definition Type set to Theta, and •A Theta curve that consists of a Bezier curve having at least four control points. When the Angle Definition Type is set to Theta with LE/TE Beta, the Beta at LE and Beta at TE values in the details view show/control the leading and trailing edge blade metal angles. These same angle values can be seen in the Angle view as the angle values of the first and last points on the Beta curve. You can also control these angle values in the Angle view by moving the second and second-last control points on the Beta curve. Note that you can parameterize the Beta at LE and Beta at TE values in the details view, which will restrict the motion of the control points in the Angle view. You can also set the second and second-last control points to be used as input parameters, causing new properties (for example, X of Angle Point 1, under the Details of Angle Point 1 property group) to be added in the details view; if you parameterize those properties, the motion of the control points in the Angle view is constrained. When the Angle Definition Type is set to Theta with LE/TE Beta, control points can be inserted or deleted for the Bezier curve with the exception that the first, second, second-last, and last control points cannot be removed. In this mode, the curve type cannot be changed.
