xTrac - Planetoid Mines · 模型 138510
A skeleton view of (2) xTrac's is shown. Planetoid Mines has engineered xTrac, a counter rotating barrel drum surface excavator similar to RASSOR, and provides for continuous excavation that encapsulates excavation and haulage to control dust. Lunar regolith is excavated by twisted springed scoops compiling minerals inward onto a bucket chain conveyor that is capable of lifting 21 liters per cycle and dumps the minerals into a covered bin for processing. Fourteen (14) 1.5 Liter buckets on a chain conveyor scoops piles of regolith from dual 360mm wide barrel drums with twisted scoops that compile mineral particles into the center. The system is made of space-qualified 15-5PH H1025 stainless steel, and is powered by two high torque electrical motors. Two xTrac in parallel opposites counter the excavation force capable of excavating 42 L/cm3 per cycle in continuous operation. A system has been modeled and simulated in COMSOL and MATLAB. A low tech prototype was constructed and tested using ilmenite soil. Capable of completing a maxium of 4 reveloution cycles per minute, excavating average of 168 L/minute. Next step is the acquisition of high quality materials and fabrication of a production model for test and evaluation.
