What is in this 1809 drawing for the history of hang gliding
and history of hang gliders?  Hello, Sir George Cayley ! Wake up Sir and join our discussion; thank you. [ Art1  Art2    ]

Discussion is invited including an examination for:

  • Tensegrity [ KS   WS  BT   LaterDefStruggle  GW    ]
  • Tensed bowing  [  Im1        ]
  • Hung mass stabilization
  • Is there something missing in the upper view in the two-part drawing?
  • Aerodynamic formation of sail for airfoil
  • Staying the lower base tube with cables
  • Glide ratio
  • Lateral flying wires
  • Pitch control capacity
  • Foundations for weight-shift control of gliding flight
  • DownTube or downStick or down tube or down stick
  • Aeroelasticity
  • Invention aspects
  • Use of arts prior to 1809
  • How does the 1809 glider relate to the 1804 glider?
  • Scaling
  • Did this get seen by Thomas Walker or not?
  • Josiah Shepard in 1867 kite frame
  • Free-flying kite hybrid: the glider (tensional towing by moving mooring mass)
  • Relation to contemporary partial framing of hybrid paragliders?
  • Relation to framed sails showing from early history to today?
  • Penetrating significance
  • Contemporary experiments with Cayley's hang glider structure? Notes, illustrations, and photographs are invited.
  • On Aerial Navigation (1809-1810), a triple paper, which appeared in Nicholson's Journal of Natural Philosophy, Chemistry and the Arts. What date for the inclusion? Do we have online access to the inclusion?   Who were the readers of that journal? Subscribers? Holders of copies? What libraries held the journal? In what classes was Cayley's article discussed? Who experimented with Cayley's concepts, figures, and devices? The seeds of the Cayley gifts spawned what further activity?
  • Sir George Cayley: the inventor of the aeroplane By John Laurence   Check your local library. London, M. Parrish [1961] [1961] Description: 277 p. illus. 22 cm
  • In what ways could Sir George Cayley be called the Father of Hang Gliders? Father of Gliding? Father of the Airplane?  See how much can be said in these regards with evidence.
  • Framing sails for hang gliders and even giving the hang glider some power assist: January of 1961  Can we sense the presence of Sir George Cayley c1809 in this Rogallo-spawned circa January 1961 powered hang glider exploration?
