Overview
Quality control of turbine blades based on external nominal
and actual measuring data
Stand alone application for MS Windows 2000 or
Windows XP
Build on the .NET framework of Microsoft
Data import and export via XML format
Communication with external application using a XML file
interface (SPC)
Usage online in the production process as well as offline for
data research

Application Concept – Evaluation
Four step evaluation of actual data:
• Automatic or interactive identification of blade Specification
• Automatic or interactive import of actual data
• Automatic evaluation of actual data on the basis of the
information contained in the Specification File
• Export of the results as XML, HTML, or ASCII file

Functional Range
• Computation of geometric characteristics as thickness,
length, stacking point, etc.
• 3D best fit by methods of Gauss, Tschebyscheff, and
modifications of these types
• Selectable degrees of freedom
• New kind of best fit procedure implementing the
extension/contraction of the nominal profile in order to deal
with large length errors (patent applied)

Features
Selectable best fit methods:
•
•
•
•
Method by Gauss (least error squares)
Method by Gauss (weighted by tolerances)
Method by Tschebyscheff (minimal maximal error)
L1-Method (least absolute error values)
Selectable best fit degrees of freedom:
• Standard degrees of freedom (rotation, translation, offset)
• Degrees of freedom for extension/contraction of section
profiles

Best Fit Transformations
Selectable best fit transformations:
• Standard (the same as in KUM, Calypso, etc.)
• Standard with offset
• Elongation - compensation of global length errors
(changes the entire profile)
• Shift Elongation - compensation of local length errors at the
edges (changes only edges of the profile)
The last two transformations change the nominal section profile
data!

BladePro Best Fit Transformations - Elongation
Right Profile
Left Profile
Left Mean Line Point
Right Mean Line Point
The section profile is
split into two parts.
This transformation
does not alter the radius
of the edges.
These parts are rotated
along a circle formed by
three points.
It is recommended for
global length errors.

BladePro Best Fit Transformations – Shift Elongation
The points of the edge profile
are shifted along a projection
line.
Transformed Edge Profile
The shifting value is the same
for all points.
Projection Center
Original Edge Profile
This transformation alters the radius of the edges. It is recommended for local length
errors at the profile edges.

BladePro User Interface - Handling
Based on Microsoft guide lines for standard office applications
• Document oriented working and management of blades
• For all user actions there are several way of realization
• Intensive use of context menus - expect an action for an
element at the element itself
• All dialogs are non modal and realize an instant preview of
changes
