USP and key details: Counter rotating fans (CRfan)
bypass flow through the pod while balancing torque, providing a higher pressure ratio,
lesser power requirement and lesser weight. The flow is bypassed through a partial
annular nozzle which keeps the flow attached while providing a flush finish on the pod floor.
The cold air from the nozzle is used to cool the braking system.
CR fan configuration with the partial annular nozzle will be looked into more detail in future development. For the competition in June, a simpler design which can be easily manufactured is being worked on with inputs from SpaceX about safety and design simplifications. This modification will reduce the pod weight further which will reduce the cost.
