Contract: NNX10CD26P
Award Amount: $99,949.00
 

Abstract:

A variety of ISRU operations will utilize lunar regolith as feedstock. The proposed centrifuging step-screw conveyor concept will provide a well controlled robust, reliable, dust-free method of transporting loose regolith over short distances (up to 10's of meters) at any inclination angle, ranging from vertical-up to vertical-down. The method offers immediate variable flow-rate control, including complete reversal of the direction of the solids flow without changing the rotation rate of the conveyor drive. This novel approach for transporting loose granular solids can provide a reliable means of moving regolith from a lower to an upper hopper
