Course Objectives
Provide students with a fundamental understanding of the physical principles governing low-speed aerodynamics and propellers, enabling them to analyze and predict their performance.
Effectively communicate technical concepts related to low-speed aerodynamics and propellers in written and oral presentations, and Present analysis results and conclusions clearly and concisely
Course Outcomes: Upon successful completion of the course, the students will be
Define, illustrate and explain the key terms related to aerodynamics, propellers, wing design parameters and propeller design variables and Explain the effect of airfoil and wing geometry on lift, drag, and pitching moment.
Analyze ideal flow over a circular cylinder, including understanding D'Alembert's paradox and the Magnus effect and Compare real and ideal flow over smooth and rough cylinders.
Demonstrate the use of Kutta-Joukowski theorem and methods like superposition, thin airfoil theory, source and vortex methods for airfoil analysis and Analyze potential flow over lifting wings using lifting line theory, vortex lattice method, slender body theory, and panel method.
Analyze the effect of subsonic compressible flow on airfoils and wings: critical Mach number, drag divergence Mach number, supercritical airfoils, sweepback influence, area rule and Apply Prandtl-Glauert compressibility corrections.
Calculate boundary layer thickness, displacement thickness, momentum thickness, energy thickness, and shape parameter, and Analyze boundary layer growth over a flat plate, understanding critical Reynolds number and Blasius solution.
Apply Froude's momentum theory and blade element theory to predict propeller performance and Analyze common propeller types and their characteristics.
