Aerodynamics Naive #3 – a brief introduction to Xflr5, a virtual wind tunnel


The previous section implemented and charted the ping-pong polar diagrams in a spreadsheet and showed a reasonble similarity, for moderate angles of attack, between these diagrams and the ones modeled using Xflr5, a virtual wind tunner. This section introduce theĀ  concept Reynolds number and it also contains a very brief introduction to Xflr5, the free virtual wind tunnel software.


Aerodynamics Naive #2 – spreadsheet implementation of the Ping-Pong polar diagrams


This section of the tutorial implements the lift and drag formulas in a worksheet, creating and charting the polar diagrams for an ultra simplified ping-pong model of an airfoil. Comparing theseĀ diagrams with ones obtained by using a virtual wind tunnel (XFLR5) we can see a decent resemblance for moderate angles of attack (smaller than about 8 degrees in absolute value).
