Model Rocket Aerodynamics On this page, you'll find links to other sites that have information about the aerodynamic forces on a model rocket, such as lift and drag.
http://web.syr.edu/~smdemar/rocketdrag.html Model rocket drag analysis using a wind tunnel to make measurements (high school level). http://www.lerc.nasa.gov/Other_Groups/K-12/windtunnel.html Explore how to measure drag with this NASA wind tunnel web page. There is also a link to NASA's FoilSim software, which can be used to simulate an airfoil in flight. http://members.aol.com/hfdy/home.htm This is where you can purchase the classic book: "Fluid Dynamic Drag" by HOERNER. http://www.desktopaero.com/appliedaero/appliedaero.html "Applied Aerodynamics: A Digital Textbook" (college level) http://www.grc.nasa.gov/www/k-12/airplane/factord.html Definition of the factors that factors that affect drag on an aircraft (high school level). http://www.grc.nasa.gov/www/k-12/airplane/dragco.html Definition of drag coefficient of an airplane. The Cd of an airplane does not equate to the Cd of a rocket, because different reference areas are used on each. (high school level). http://www.grc.nasa.gov/www/k-12/airplane/area.html Definition of wing area, which is used to determine the lift and drag on a airplane wing. This area is not the same as the reference area of a model rocket. That area is the circle of the body tube where the fins are attached, or the base of the nose cone. http://aero.stanford.edu/WingCalc.html
