The Human-Powered Wing
 
 
  
 
" There is a way in which human and machine, connected organically, initiates propulsion in the manner of the swan...and I, Denis V. Curry, a sculptor, am the first to discover it."

The achievement of propulsion from rest and acceleration by Curry's prototype, shown in the film clip above, affirms in both practical terms and in the calculus the possibility of take-off and flight in this mode.
Denis V. Curry's variable-geometry ornithopter is herein claimed to be the first such machine to initiate propulsion solely by means of the wing movements.The wings and their mechanics of operation are principally based upon, and derived from, those of birds - particularly the swan - and insects.

Propulsion from rest in still air is the essential first event in the continuum leading to flight simulating nature. The achievement of propulsion from rest and acceleration by Curry's prototype affirms in both practical terms and in the calculus the possibility of take-off and flight in this mode.

D. V. Curry's breakthrough has been recognised by the Royal Aeronautical Society, which elected him an Associate and published his paper:- 'Propulsion of a Variable-Geometry Ornithopter', Proc: Symposium of the Human-powered Aircraft Group of R.Ae.S., paper 7. 10.2.75.

The right of D. V. Curry to be identified as the creator of the above machine has been asserted by him in accordance with the Copyright, Designs and Patents Act 1988.
