GE J79 TURBINE STUDY

 

Product Prototyping to better understand axial flow performance on a turbo-jet

CLIENT:

Turbo-machinery course study, Universidad Iberoamericana

ROLE:

Undergraduate solo designer focused on engineering students as users

CHALLENGE:

How might we develop an understandable physical model of a turbojet to better grasp axial flow and design parameters

OUTCOME:

This project involved investigation, CAD drawing and computer-aided thermofluid analysis. Done for my Turbomachinery course, this paper had a clear objective: to translate theoretical knowledge of the Brayton cycle into practical construction of a scaled model and examination on the performance of each of the components of the full size turbojet. MatLab™, SolidWorks™ and Ansys Computational Fluid Dynamics™ were used to determine theoretical and real efficiency (thermal and volumetric), overall thrust obtained, maximum work capacity, as well as the load, flow, power and losses of the turbojet. Afterwards, all the components were 3D printed and assembled.

The main take away was the insight into the importance of design parameters on turbo machines, where geometry, materials, atmospheric and fuel properties are all deciding factors on the turbine’s efficiency.
