ABSTRACT
A compressive design and analysis of a turbofan engine is presented in
this paper. The components of jet engine have been analyzed based on mechanical
design concept. An attempt has been to select materials based on sustainability
and green design considerations. The energy content (e) of the materials has
been one of the parameters for material
selection. The choice of material has a substantial impact on cost,
manufacturing process, and the life cycle efficiency. All components nose cone,
fan blade, inlet shaft, including compressor has been solid modeled using
Siemens NX 11.0 CAD software. The finite element analysis of every component was performed and found
safe. A tolerance analysis was performed before assembly of the turbofan
engine. A numerical analysis was completed on blade and inlet geometries to
determine a more efficient turbofan engine. Thermal analysis was executed on
the cone and suitable corrections were made. Finally, the cost and the total
energy were estimated to show how much energy is needed to manufacture a
turbofan jet engine.
