The aerodynamic formula used (the simplest and safest existing), which could be called ‘living wings’, is ignored by most aeronautical specialists. Yet it is, paradoxically, one of the oldest manners of flying, even recommended by Octave Chanute (known as “the Father of Aviation”) in 1902 and, finally, nearest to that of the birds, which fly regularly in turbulent air conditions and never stall or get into spins. |
Reminder of ‘living wing’ aircraft
Perfect machines, therefore have been ‘also’ boycotted by the medias (…paid by fixed-wings aircraft ads)
