Learning Objectives
16.100 is a course about aerodynamics, i.e. the study of the flow of air about a body. In our case, the body will be an airplane, but much of the aerodynamics in this course is relevant to a wide variety of applications from sail boats to automobiles to birds. 16.100 has a set of learning objectives which you should always keep in your thoughts as the semester progresses. The entire course is structured to (hopefully) help you achieve these objectives. Specifically, students graduating from 16.100 will be able to:

Formulate and apply appropriate aerodynamic models to predict the forces on and performance of realistic threedimensional configurations;

Assess the applicability of aerodynamic models to predict the forces on and performance of realistic threedimensional configurations and estimate the errors resulting from their application;

Perform a computational and experimental aerodynamic analysis and design together with members of a team.
Comment on Aerodynamic Models
An aerodynamic model is simply a method to estimate the aerodynamic performance (e.g. the lift or drag) of an object (e.g. an airfoil, wing, or airplane). An aerodynamic model could be based on experiments, computation or theory but often lies in the middle ground using a judicious combination of all three approaches. For example, an aerodynamic model might be incompressible thin airfoil theory; or, an aerodynamic model might be incompressible thin airfoil theory with a skin friction drag estimate; or, an aerodynamic model might be a wind tunnel experiment at low speed with theoretical corrections for wall effects and higher speed flight conditions. In 16.100, a variety of aerodynamic models will be covered which could then be combined to produce a more complex model as dictated by the application. Specific aerodynamic models that students will encounter may vary slightly from semestertosemester but will generally include: 2D/3D potential flows (incompressible to supersonic) including panel and vortex lattice methods; boundary layer methods including the effects of transition and turbulence; coupled inviscidviscous models; 2D/3D Euler and NavierStokes computations; wind tunnel testing.
Measurable Outcomes
Students graduating from 16.100 will be able to:

Contribute substantially as an individual to the design and execution of a computational and experimental aerodynamic analysis of realistic 3D configuration together with members of a team (team project reports).
Comment on Basic Elements
The basic elements of a model includes the critical features which produce a valuable predictive method. For example, consider a 2D panel method. The basic elements would include: all of the underlying assumptions of incompressible, potential flow; the discretization of an airfoil geometry into a set of line segments on which potential flow solutions are distributed; the satisfaction of flow tangency at panel control points; the global influence of an individual panel on all other panels; the imposition of the Kutta condition; etc. However, the basic elements would not include the more detailed aspects of the method which while important, are not critical to understanding how the method works. In the 2D panel method example, it would not include the details of the calculation of the influence coefficient of a general source/vortex/doublet panel; the solution of the large linear system of equations; etc.
General Pedagogy and Assessment Strategy
The skills to be gained in this course are basically of three types:
For each skill, a different pedagogical and assessment strategy is used. Analytical skills are taught and/or assessed through the textbook reading, homework assignments, the written exams, and, to a lesser extent, the team project. Conceptual skills are taught and/or assessed through inclass conceptual questions, the oral exams, and, to a lesser extent, the project and the written exams. Integrative skills are taught and/or assessed through the project and written exams, to a lesser extent, the homework and oral exams.
Grades will be based upon the following weightings:

Reading, Homework Assignments and Late Policy
Students are expected to complete assigned reading prior to discussion of the topics in class. The homework will be largely based on the assigned reading material with some problems based on difficult material from previous reading and lectures. The homeworks are individual efforts; while students are encouraged to discuss homework problems with each other, what is turned in must represent the student's own understanding of the material.
Pastdue homework will generally not be accepted. For unusual circumstances, exceptions could be permitted.
Team Projects and Labs
Students will participate in an integrative team project developed with The Boeing Company concerning the aerodynamic analysis and design of a BlendedWing Body (BWB) aircraft. During the first two months of the semester, students will complete assignments to learn the basic skills necessary to analyze the BWB aircraft. In the final month of the semester, teams of approximately three students will complete a redesign of the BWB. These teams will be responsible for completing the design project and documenting their results in a design report.
The weekly Labs on Wednesdays from 34 pm and 45 pm will be held in the electronic classroom. Students will be assigned to one of the sessions on the first day of class based as much as possible on preference. During the first two months of the semester, the staff will guide the students through the completion of the assignments. These assignments will be completed in pairs that the students can select, however, the pairs must be different for each of the assignments. Then, in the final month, the Labs will be dedicated to the teams working on the design project with staff in attendance to provide guidance. The students will be assigned to the design teams by the staff. Attendance will be taken for all lab sessions.
The total individual student grade on the design project will be based on a team project grade (20%) and an individual contribution grade (80%). The individual contribution will be assessed from three sources:

Instructor interactions with the teams throughout the semester including work session attendance,

Written (emailed) evaluations after each milestone by all team members of the contributions of each team member (including selfevaluations), and

Delineation within the written reports of an individual's contributions.
Exams
The exams will have a takehome written portion and an oral portion. Students will have a few days to complete the written exam (see the calendar section for the specific sessions, the takehome exams will be distributed and due). The written exams will then be followed by an oral exam. The oral exams will be largely, though not exclusively, based on the questions from the written exam. The oral exam will be 30 minutes in length, conducted by Prof. Darmofal. The written exam questions will be similar to homework questions focusing mainly on quantitative and integrative abilities. The oral exams will focus on conceptual understanding.
