Lecture Goals and Motivations Introduce the notion of modeling Discuss the basic models used in astronautics Goals Def:  Why? The main activity of engineers is technical. Engineers: Characterize Analyze Design Operate systems. We want to “get answers” and measures related to performance, dimension,... of systems.  To perform these tasks, engineers need mathematical representations of the systems considered. Modeling consists of the activity of formulating mathematical models to represent the physical reality MAE 146:  Astronautics Introduction BFV, 01/07/2009 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
