An explanation for thisphenomenon can be the smaller speed than needed. A proof for thisexplanation is the enlargement of the divergence in smaller speeds (for30 m/sec). The model is trimming only on deep stall (very negative liftcoefficient). There is a need to consider this phenomenon on the controlsection.Additional Conclusions:1. Additional strengthening of the wind tunnel model is needed so itcan be able to carry the lift loads of 80 m/s air speed, and by thatto get the necessary Re number and get more accurate results.2. Additional experiments have to be performed on the wings andcanards in order to evaluate their mutual effect on each other.38
