Keynote Speech #5: Contra-Rotating Fan System for Propulsion of the Hyperloop Pod

Keynote Speaker: Dr. Shaaban Abadllah


We propose a contra-rotating fan system for propulsion of the Hyperloop Pod in a partially vacuumed tube. The contra-rotating stage features two rotors with opposite direction of rotation that provides higher pressure ratio, torque balance, lower RPM compared to a single stage fan. The fan stage is placed in front of the Pod and can be detached from the Pod body in case of fan failure for safety of the passengers. The air from the fans discharge in a transition duct leading to a partially annular convergent nozzle. The nozzle exit is located on the upper half of the Pod tail in order to accommodate the levitation hoverboards, and brake systems located at the bottom surface of the Pod. Numerical simulations of the propulsion system are performed using NUMECA software.
