## Aerodynamics Index

#### Glenn Research Center

 Here is a list of all the topics available from the Beginner's Guide to Aerodynamics (BGA) site. Clicking on the title will deliver a page with a slide and a scientific explanation of the contents. Click on the word "Animated" for the animated version of selected pages. If the number and variety of pages seems too intimidating, consider taking one of our Guided Tours through the web site. Another method for reaching students, teachers and lifelong learners is the use of Distance Learning. While preparing presentations for students, many Power Point files have been developed for the Digital Learning Network using information from the BGA. Another group of Power Point presentations has been prepared concerning the exploration of space. Students and teachers are encouraged to copy the Power Point files to their own computers and to modify them as desired for their own presentations. We have also created a home page for all of our movies featuring Wilbur and Orville Wright. * Animation files can be large (average 350K bytes) ** Java Applet NASA Glenn History and Missions Activities FoilSim Activities Basic Aerodynamics Activities Aerospace Lesson Plans Cross-Word Puzzle Activity Airplane Gallery Three Phases of Matter Newton's Laws of Motion ..Movie Newton's First Law - Inertia Newton's Second Law - Force Newton's Third Law - Action & Reaction Torques (Moments) Forces and Torques Equilibrium - 2 Forces Equilibrium - 3 Forces Equilibrium - 2 Torques Functions Rectangular and Polar Coordinates Area Volume Displacement, Velocity, Acceleration Angular Displacement, Velocity, Acceleration Scalars and Vectors Comparing Two Scalars - Ratio Comparing Two Vectors Vector Addition Vector Components Trigonometry Sine-Cosine-Tangent Ratios in Triangles Pythagorean Theorem..Interactive** Conservation of Mass Conservation of Momentum Conservation of Energy Euler Equations Bernoulli's Equation Navier-Stokes Equations Lift of Rotating Cylinder ..Interactive** Ideal Lift on Spinning Ball ..Interactive** Ideal Flow Around Spinning Ball ..Interactive** Conformal Mapping...
