Inlet Stack Improvements

Project Summary

Safran is a company that builds and sells Jet engine test cells. These test cells are used to simulate real life operating conditions for jet engines before they are mounted to their airframes. This project’s focus is on improving the distribution of airflow through finding modifications to the inlet stack of the Jet engine test cell. The components that can be modified include a stainless steel egg crate structure in addition to the exterior building structure itself.

Design Goal

Find a way to adjust the current design of the 9m by 9m cross section inlet stack of a jet engine test cell that reduces the effect of cross-wind on the uniformity of the airflow downstream (near the actual testing area for the jet engine). The design should improve the uniformity of airflow while also reducing the material used in the stainless steel egg crate. Additionally, the design must allow for easy inspection and maintenance access to ensure component safety regularly.

Design Constraints

• The design shall give a VDI of less than 15%.
• The design shall consider a maximum wind speed of 46 miles per hour.
• The design shall reduce material by 5%.
• The design shall ensure easy and regular maintenance and inspection is available.
• The design shall consider thermal conditions from freezing to full engine operation.
