us keenly aware aircraft stability tradeoff process design Attendees learned Otto Lilienthal artist fly creations prior untimely death Dicks second lecture somewhat analytical dealing new twist classical aerodynamic theory stunning leading edge technology wing design geometry unfortunates unable attend will undoubtedly see technology soon innovative method will revolutionize wing design Dicks approach will important molded wings increased performance new design concept may nonscientifically called inverse coefficient induced drag Dick termed induced lift lift generated inhibited vortices created wings geometry specifically shape tips Although soaring aircraft designers feel optimized wing planform Schuemannized shape Dick did advocate studying demonstrating possibilities enhancing performance turning tips wing up specified angle also proposed optimized wing shape may have found yet modelers could play integral role defining discussion certainty challenged existing

classical aerodynamic theory stunning leading edge technology wing design geometry unfortunates unable attend will undoubtedly see technology soon innovative method will revolutionize wing design Dicks approach will important molded wings increased performance new design concept may nonscientifically called inverse coefficient induced drag Dick termed induced lift lift generated inhibited vortices created wings geometry specifically shape tips Although soaring aircraft designers feel optimized wing planform Schuemannized shape Dick did advocate studying demonstrating possibilities enhancing performance turning tips wing up specified angle also proposed optimized wing shape may have found yet modelers could play integral role defining discussion certainty challenged existing

spending hours just watching talking doing some flying signing autographs amazing watch him took opportunity study what described problems facing RC Soaring community gave two enthusiastic talks first hosted Dr Gary McVay Battelle Laboratories concentrated longitudinal stability fun-filled lecture utilized number model aircraft demonstrate challenges presented problem have overcome Dick also made us keenly aware aircraft stability tradeoff process design Attendees learned Otto Lilienthal artist fly creations prior untimely death Dicks second lecture somewhat analytical dealing new twist classical aerodynamic theory stunning leading edge technology wing design geometry unfortunates unable attend will undoubtedly see technology soon innovative method will revolutionize wing design Dicks approach will important molded wings increased performance new design concept may nonscientifically called inverse coefficient induced drag Dick termed induced lift lift generated inhibited vortices created wings geometry specifically shape tips Although soaring aircraft designers feel optimized wing planform Schuemannized shape Dick did advocate studying demonstrating possibilities enhancing performance turning tips wing up specified angle also proposed optimized wing shape may have found yet modelers could play integral role defining discussion certainty challenged existing paradigms Dick finished explaining Eppler 374 387 airfoils originally designed 1964 modelers met hiking said WSJ given him food thought would designing some applicationspecific airfoils new breed gliders/sailplanes great news since Dr Dan Somers have enhancing Eppler computer code take account occurring phenomena airfoils called bubble drag airfoils sections Dick will offer no charge should
