BladeGen now supports a user defined file import/export mechanism, UserIO, that is now used to support several previously supported file formats. These include the file formats listed below. Moving the support for these file formats to the UserIO mechanism ensures the completeness of the mechanism and allows users to extend the file formats to support their needs.
|
File Format |
Description |
|---|---|
|
This file format is simple, yet almost completely describes a blade model (missing LE/TE Treatments). This file is now supported through a UserIO module. | |
|
This file format specifies a meridional layer, a reference point, rotation angle, and a curve for each side of the blade. This file is supported through a UserIO module. | |
|
This file format is for data import only. This file is now supported through a UserIO module. |
This section describes the generic data file format for BladeGen. The file is an ASCII file that uses space separation between values.
Note: Angular values must be in radians.
text enclosed in {} is a data item
text enclosed in () is a comment
text enclosed in [] is optional
{number of blades}
{number of splitters} (0 is main blade only)
(for each blade, main and splitter)
{pitch fraction} (Ignored for main blade)
{number of layers}
[N] [T] (Normal or Tangential Thickness Flag)
(for each layer)
{span fraction} {number of points} [a][t][b]
(for each point)
{r} {theta} {z} {thickness}

RTZT Thickness Flag - N
This flag is used to specify that the thicknesses are to be interpreted as Normal Thicknesses.
If the flag is not included, the user will be prompted for the proper interpretation of the thickness values.
RTZT Thickness Flag - T
This flag is used to specify that the thicknesses are to be interpreted as Tangential Thicknesses.
If the flag is not included, the user will be prompted for the proper interpretation of the thickness values.
RTZT Layer Usage Modifier - A
Including an ’a’ or ’A’ specifies that the data be used for angle definition only. If the modifier is not included, the default is for the data to be used for both angle and thickness definitions.
RTZT Layer Usage Modifier - T
Including an ’t’ or ’T’ specifies that the data be used for thickness definition only. If the modifier is not included, the default is for the data to be used for both angle and thickness definitions.
RTZT Layer Usage Modifier - B
Including an ’b’ or ’B’ specifies that the data be used for both angle and thickness definition only. This is the default modifier if none is specified.
