In many instances, the design of new turbofan engine is an iterative process of optimizing engine cycle parameters (i.e. thermodynamics) and executing preliminary design geometry of engine components (i.e. aero design, constrained with structural, manufacturing, fitting in engine layout, size, weight & other requirements) for the best performing realizable solution. Consideration of the preliminary design of the engine in the totality of these requirements seems to be an interesting topic to address.
Coupling cycle calculations with detailed preliminary design of turbomachinery components for getting optimized turbofan engine is the topic of this article. Detailed preliminary design means generating geometry and getting flow data and performance for each component of the multistage geometry of the engine, sufficient in the scope to move design process to 2D and 3D considerations.
