He developed Hargrave's basic design, adding additional lifting surfaces to create powerful man-lifting systems using multiple kites on a single line.

The aircraft is a three lifting surface design, with both a small forward wing, and a small conventional horizontal stabilizer in a T-tail configuration.
13.
Instead, the pilot just grabs the lifting surface by hand ( using a rigid frame that hangs from its underside ) and moves it.

"We all know that ice can have a detrimental affect on lifting surfaces, " said Arnold Scott, a senior air-safety investigator with the National Transportation Safety Board.
15.
The TMR lacked any lifting surfaces, such as wings; instead, lift was generated purely by the thrust generated by the Nene engines being directed downwards against the ground.
16.
This drawback might have been made still more troublesome if another membrane, called the uropatagium, spanned the space between the hind legs, adding lifting surface to the pterosaur's wing.
17.
Both the V-173 and the XF5U featured an unorthodox " all-wing " design consisting of flat, somewhat disk-shaped bodies ( hence the name ) serving as the lifting surface.
18.
As configured, the Starship is difficult to stall : The forward surface stalls before the main lifting surface, which allows the nose to drop and more-normal flight to resume.
19.
The Fernic T-9 can be seen as a conventional twin engined monoplane with the addition of a long nose mounted canard foreplane to provide two lifting surfaces in tandem.
20.
With an initial estimate of the pressure distribution on the wing, the structural designers can start designing the load-bearing parts of the wings, fin and tailplane and other lifting surfaces.
