Hi group, Can any one tell me or direct me to info on placement of vortex
generators? I would like to experiment on my zenith. What are they placed in relation to, i.e.; centre of pressure, flow separation or? Thanks,................Stew |

Thanks,................Stew It is different for every airplane, and unless you know what you're doing, they are unlikely to work at all. The VG is a method of re-energizing the boundary layer just before it seperates and turns turbulent as it works against the adverse pressure gradient. The first step will be to determine where the seperation occurs. Yarn tufts or oil slicks will help here. The second is to model the pressure gradient. Look for JavaFoil and other such programs on the net for help in this. -- This is by far the hardest lesson about freedom. It goes against instinct, and morality, to just sit back and watch people make mistakes. We want to help them, which means control them and their decisions, but in doing so we actually hurt them (and ourselves)." |
