DescriptionF.H. Wenham's aerial designs of 1866.jpg |
English: Fig. 1: Top view of a gliding machine illustrating the total surface area required to sustain aloft a human of average weight (note the wing's high aspect-ratio). Fig. 2: Rear view of the same design, showing the prone position which Wenham suggested for the gliding machine's operator. Fig. 3: Front view of a multi-winged gliding machine trussed with "thin bands of iron" (c) and vertical wing struts (d). Fig. 4: A more refined design, incorporating small wing-like propellers on each end, operated by motion of the operator's feet and arranged so that the propellers could be operated more on one side or the other, thus enabling the machine to turn by generating more lift on one side than one the other, or together. Fig. 5: An even more refined design, with wing-like propellers at the ends of long arms, a cellular wing structure with vertical supports (struts), wing trussing, and a horizontal position for the operator. Fig. 6: A side view of the machine depicted in Figure 5. |
