Description

The Turbine Based Combined Cycle Exoskeletal Engine concept presents a creative approach to achieving high Mach number flight, starting from ground speed. Key design aspects that move away from traditional jet engine designs is having all the rotating turbomachinery mounted on rotating drums / discs, thereby removing the need for a central shaft. This research addressed the initial compressor blade design, FEA and material selection. These areas play a critical role in developing the low-speed engine of the TBCC ESE.
