The crucial design parameters include mass flow rate, compressor pressure ratio and turbine inlet temperature. After running this program, the designer can get reference data to the efficiency of each component. This efficiency data then be transferred into the following components' design programs as input. This program also generates the design fuel rate and exhaust area, as well as all the total temperature, pressure and other flow property at each stage in the jet engine.
This program takes several design parameters as input, for example pressure ratio, mass flow rate, RPM and etc, then generates a plot with certain output geometry parameters and flow parameters for users to select and further optimize the impeller. Once the user determine the impeller design, he can transfer these output parameters to the diffuser design program downstream.
This program takes several output parameters from 1D Impeller Design program and several diffuser design parameters as input, for example, the number of vanes or the diameter of vane-less area, then outputs a check list for geometry compatibility of the diffuser. While determining the diffuser geometry, users should refer to the following documents to choose the suitable length and angle for the vane diffuser.
This program takes several design geometry parameters as well as the fuel property as input, then specific output parameters will be calculated to check for the combustion efficiency and validity. The length of each zone will be estimated as well.
This program takes several turbine's performance parameters and outputs two plots for users to select the size of NGV and turbine rotor that meet their requirements. The following folder describes the full calculation within the program.
