Delta-Conyne
The Delta-Conyne (DC) is a very popular kite, combining the cellular structur of a Conyne kite with the wings of a delta kite. The inventor of this kite is at this time not known to me. The DC is made aspecially for light winds, but can also handle heavy winds. The delta shape and the aspect ratio can widely be altered; it's no problem to scale the kite up or down. Both central cells are made of three square panels; naturally you have to add hems for the longeron pockets.
Dimensions for the Delta-Conyne (in cm)
Constructional details:
- In practice the two-leg-bridle (48 cm (front) and 72 cm) can made a little bit longer. The bridle-points w1 and w2 are in the middle of the cells.
- Spars: 3x longerons (spines) (120 cm) and 2x leading edge spars (144 cm) made of 6mm Carbon, spreader made of 8 mm Carbon.
Twin-Delta-Conyne
Dimensions for the Twin-Delta-Conyne (in cm)
Constructional details:
- The Twin-Delta-Conyne is constructed same as the Delta-Conyne, except for the additional center panel and keel cells.
- You also need four additional cross spars
(120 cm, 6 mm Carbon) on leading and trailing edge and the center vents of the conyne panels.
Altogether you need eight longerons and cross spars (120 cm, 6 mm Carbon) for stabilizing the center box in addition to the keel longerons (2x 120 cm, 6 mm Carbon).
Then you need the wing spreader (8 mm Carbon), and both wing spars (2x 144 cm, 6 mm Carbon).
- There are two solutions for bridling. You can connect w1 to w2 and w3 to w4 with two normal two-leg-bridles (like the simple Delta-Conyne). Then you attach both bridlepoints with a third line to have a new bridlepoint (Cody-Bridle).
Or you connect w1 to w3,
and w2 to w4.
Then you can attach a two-leg-bridle line on both line centers (Rokkaku-Bridle).
