The first lectures notes focus on the preliminary design of state-of-the-art
turbofan engine for the propulsion of civil aircraft. Issues like thermodynamic cycle, mission analysis, and off design operation (operating line) are addressed. Practical examples are presented. Once this important phase is completed, the different design teams have the boundary conditions to start the design of each component. The fan must cope with a number of constraints in terms of mechanical resistance, noise and surge margin. The aerodynamic design involves both subsonic flow at the hub and supersonic flow at the tip. The design of the booster (low pressure compressor) is then addressed where the multistage operation and the matching between successive stages are important concerns. Moving to the high pressure compressor, the notes first describe the preliminary design based on through flow calculations. Then, airfoil design, from 2D sections to stage matching optimization, is addressed. Current trends for future HPC configurations are outlined. Learn More
