......What do you say guys ? Should I go to the
slope and start blowing ?-).....
I think getting out more could be a good start!

you are right Jo, on one of our DS slopes I always land behind the rotor,
and some times I can stay up for a few passes in the back side of the slope,
not DSing... |

I'm not sure you need low
pressure to get lift. The fact that the airflow is still moving upward behind the slope will generate lift either way. I don't see how simply lowering the pressure of the air around the glider will impart any lift to the airplane unless the air is already moving upwards anyway. |

Since moving air has lower pressure (the air above share layer) this |

I think I understand what
you're saying, but I just can't see how you could generate the speeds we typically get if the "DS effect" were just due to air moving up the backside (which may or may not be present). If that were the case, you should be able to generate similar speeds on the frontside. |

what jo means, is that you have
this upmoving airflow because of the low pressure above (just like above a
wing airfoil) Marcel |
