Manufacturing of a Ceramic Turbine Rotor for a Compact Jet Engine

Abstract

The primary goal of this study was to develop a low-cost, timely, scalable manufacturing method that produced a ceramic turbine that can be tested as a drop-in replacement on a JetCat P400 small scale gas turbine engine. Thisresearch compared two processes for manufacturing a ceramic turbine utilizing a pour casting method and 3D printingusing stereolithography ceramic manufacturing (SLCM). The pour casting method used Silicon Nitride to create a castturbine using a sacrificial 3D printed mold. The SLCM method evaluated producing an alumina turbine using an ADMATEC Admaflex 300 SLCM printer to directly print a ceramic turbine. This study covers the finite element analysis of multiple designs and detailed overview of the varying manufacturing processes as well as lessons learned. It also covers how the turbines would be tested and incorporated into JetCat P400.
