'Mechanics of Flight'.
It's so simple it's quite confusing.
I have always had a sneaky suspicion that he wrote this in order to justify the construction of complex airborne machines by the British aviation industry when it really had nothing more than the theoretical technology upon which to base its forays into actual aircraft design and construction.
By the same author and rather even easier on the little grey cells is:
'Flight without Formulae'
It is readily available on the net wave.
I suggest you dip into a second hand copy of that. It used to be available in paperback and is actually relatively readable in a sort of Bernoullian way. Much more fun actually than its big daddy, rather like 'War and Peace' with the rather boring peace bits excised from the tome.
