Mechanical Design to Adapt Changes to Existing Universal Test Bed Facility of Turbojet Engine for the Turbofan Engine

Abstract:

The existing Universal Test Bed (UTB) is a facility to ground test Turbojet Engines before installation on the aircraft. This work provides a feasibility study to adapt changes to this UTB for the Turbofan Engine. Necessary design modification of existing UTB is performed by applying propulsive and structural analysis for the adaptation of Turbofan engine. Physical measurements of the UTB and the mounts of Turbofan Engine reveal their mutual compatibility. Based on these measurements, six different CAD models are generated in Solid Works^® and analyzed in ANSYS^® Workbench. After grid independence check, validation of the model with applied loads and the boundary conditions was done through comparison of analytical calculations with those of a simplified CAD model. Based on minimum stress vis-à-vis maximum Factor of Safety (FOS), the best design is finally selected through this research.
