Centrifugal Compressor

thingiverse

This centrifugal compressor was specifically designed for Dr. Kazuya Tajiri at Michigan Technological University to aid in research of rocket engines. The impeller was significantly enhanced from Christophe Augier's Centrifugal Impeller model. A collaborative effort between David Eychaner and myself led to the creation of the casing. Below, you will find the original CAD files and STLs used for this compressor design. It consists of three main components. Assembly is straightforward: simply place the impeller on top of the lower casing and then secure the upper casing onto the connecting rods. A DC motor can be easily connected to the impeller via the lower casing. The total cost to print this compressor is approximately $2.45. It can run off a compact RC motor. The specific motor used during design cost $13.99 on Amazon at https://www.amazon.com/dp/B0752D1JCC/ref=psdc_2234129011_t3_B076B1GGWJ. This adds up to a total compressor cost of $16.44. Compared to other designs, this model offers a considerable cost reduction - even the least expensive comparable design costs $118.42 on Patrick's Supply at https://www.patrickssupply.com/Fasco-A202-1-Speed-Lennox-Draft-Inducer-Blower-11-p/a202.htm. This results in a substantial savings of $101.98 for our model overall.
