Unformatted text preview: MAE 146: Astronautics MODELING Lecture Goals Present the notion of modeling Review the fundamental models used in Astronautics Modeling Goals The main activity of an engineer is technical: Engineers characterize, analyze and design systems To perform these task and obtain answers , engineers need mathematical representation of the systems considered: This is called modeling . MAE 146: Astronautics Introduction BFV, 01/07/2008 1 Modeling Models can be? (examples) MAE 146: Astronautics Introduction 2 BFV, 01/07/2008 Modeling Models can be? (examples) Algebraic: PV = nRT (perfect gas law) differential: F = m r'' (Newton's law); U xxxx +kU xx = F (beam) Discrete: digital communications; y(n+1) = f(y(n)) Probabilistic: manufacturing quality analysis.
