Optimizing Engine Architecture: Bypass and Compression Ratio Trade-offs in Next-Generation Propulsion
This presentation examines the critical design parameters governing turbofan engine architecture: bypass ratio (BPR) and overall pressure ratio (OPR). Through analysis of commercial and tactical applications, material constraints, and emissions considerations, we demonstrate why high-bypass architectures dominate subsonic aviation and explore breakthrough technologies like CFM’s RISE program that promise 20% fuel consumption reduction.
