A state-of-the-art Centrifugal Compressor design is in development, tailored specifically for use in turboshaft applications. Utilizing advanced Siemens NX 10 modeling techniques, intricate 3D designs are created to optimize performance in both Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA). Impellers boast precision-crafted dimensions, with an inlet diameter of a substantial 146 mm, allowing for seamless airflow entry. In contrast, the maximum impeller diameter is a notably larger 237 mm, further facilitating aerodynamic efficiency. Within the design, 2x11-bladed rotors are seamlessly integrated alongside 19-bladed stators, showcasing a carefully calculated blend of radial and tangential motion. Such intricate specifications promise unparalleled mechanical efficiency. In terms of design parameters derived from exhaustive CFD analysis, key performance metrics stand out. Notably, an astonishing pressure ratio is achieved at an impressive 3.34. A moderate mass flow rate of 1.6 kg/s further underlines the system's prowess. An impressively high isentropic efficiency above 0.83 demonstrates mastery over thermal losses, ultimately bolstering the system's energy retention. Notably, calculations indicate corrected spool speed peaking at an exceptional 37000 rpm, exemplifying engineering prowess. FEA modeling conducted using high-performance materials like titanium alloys has verified optimal stress management within key areas of design.
