ESPROP was developed to fit the requirements of a propeller manufacturer using third party blades in custom constant speed hubs. The problem was to select the optimum blade for a particular airframe, engine and operating points. The system consists of two components:
The system has two chief applications:
ESPROP databases can be built from any blade geometry that has been loaded into XROTOR, over any range of operating parameters for which XROTOR will converge solutions.
Download ESPROP v0.8Available under the terms of the General Public Licence. By downloading the software you agree to abide by the GPL conditions.
Esprop08w.zip includes sources, plot library, sample database, and documentation. Building in Unix/Linux/OSX requires X11 support and C and Fortran compilers. For Windows users a Win32 binary is included in the package.
Note that ESPROP 0.8 is included in the CROTOR 755-ES1 builds. This distribution is intended for those not needing CROTOR who wish to view ESPROP databases generated by others.
