This is the 'pumpkin seed' of which the Aerodynamic Streamlining Template is derived.Jaray derived his from a Cd 0.045 streamline body of revolution/airship form.Wolfgang Klemperer,who had his graduate degree in engineering in 1922 did the wind tunnel measurements for Jaray at the Zeppelin works of which they both worked.It measured Cd 0.13 in its 'best' edge configuration with wheels,on the 'ground.'
I used a Cd 0.04 body for the 'Template.'
