Aerospace Aerodynamic efficiency and static longitudinal stability

  1. Oct 12, 2012 #1

    I am looking for research results, report etc. dealing with
    -aerodynamic efficiency and static longitudinal stability-
    Couldn´t find anything useful yet!

    Any ideas would be very much appreciated.
    Best Regards,

    What exactly do you mean? Do you want reports dealing with either aerodynamic efficiency OR static longitudinal stability? Or a report with aerodynamic efficiency as it relates to static longitudinal stability?

    How both factors are related to each other!

    usually called "Trim Drag"...

    the sweet spot is for the CG to be at the neutral point so that tail is making no lift.. but providing pitch stability through an active system (SAS)

    a sailplane is a good example.... the CG is just enough fwd of the neutral point that a pilot can control the plane... high pitch damping helps...
