Developed by PCA since 1990, the code already contained a large number of features vital to axial compressor design. They include: a range of verified loss and deviation models, split-flow fan capability, transonic blade inlet conditions, and spanwise mixing.
Recently added, in the earlier 2006 release, v6.3, were the following:
- application to high pressure ratio multistage compressors with as many as 15 stages
- an improved design mode
- blade force calculation
- an entirely new environment, based in Excel, in which to run the code and to post-process results
- additional loss model: Miller and Wright
In the latest release, v6.5, the following new features have been added:
- improved handling of Miller and Wright endwall losses
- facility to customise radial loss variation
- improved treatment of split-flow fans
- improved treatment of near-choke flow
