ME 4183: Compressible Flow and Propulsion Systems
Undergraduate course; offered in Fall 2014
Application of mass, energy, and force balance to compressible fluids, analysis of one-dimensional steady flow, isentropic flow, adiabatic flow, flow with heat addition, supersonic flow, and shock waves. Introduction to the analysis and design of air-breathing engines for aeronautical transportation.
To desing/ analyze, 3D print, and performance test a small rotor intended for a multicopter unmanned aerial vehicle (UAV). Based on rotor propulsion/ airfoil theory, your team (3-4 students) will desing a small rotor on CAD which will be 3D printed and tested on a rotor test-tower to measure key performance parameters: thrust, torque, and power. You will then compare your experimental results and figure of merit to numerical results based on blade element theory.

Team Lab Testing
Undergraduate/ graduate course; offered in Spring 2014
Study of the properties and behavior of airflow as it relates to aerodynamic bodies and their effect on the forces generated. Incompressible inviscid and viscous flow: continuity, momentum, and energy equations, Bernoulli’s equation, circulation, vorticity, Laplace’s equation and elementary flows. Application to flow over airfoils and finite wings: Thin airfoil theory, Kutta-Joukowsky Theorem, d’Alembert’s paradox, vortex sheet, vortex panel method, Prandt’s Lifting-Line Theory, vortex lattice method, etc. Aerodynamic and conceptual design considerations and computational analysis of fixed-wing aircraft and helicopters: Excel spreadsheets, Digital DATCOM, and computational fluid dynamics.
The course project is designed to develop your ability to design and/or analyze the flow and forces of an aerodynamic body and communicate your results in written report format. In general, teams of two or three students may work together and propose the “aerodynamic body” of your choice. Students are encouraged to utilize the numerical analysis tools presented during the course. Graduate students enrolled in ME 5013 are required to come up with an original design or research-level topic for the project.

Graduate course; offered in Fall 2013
Concepts of errors that lead to uncertainty in experimental measurements, and data analysis including statistics, probability distributions, graphing, and curve fitting. Modern data acquisition systems (i.e. Labview) and transducers for displacement, force, torque, and strain measurements will also be discussed in the context of the three course laboratories. A student-defined course project presentation and report is also required.
The course project is designed to develop your ability to design, test, and analyze the uncertainty and performance of a physics-based project utilizing the methods learned in the course. In general, teams of 3-4 students may work together for this design and experimental project.
Undergraduate course; offered in Spring 2015
Laboratory intensive with fundamentals of measurement systems, descriptive statistics, probability, error, error propagation, confidence intervals, hypothesis testing, correlation, linear regression, introduction to DC and AC circuits, filter circuits, bridge circuits, strain gauges, lab writing, and data acquisition.
