Parasled kite 

William Ellison patented his "flexible kite" in the early 1950s. Frank Scott and Ed Grauel then developed this design into what is now known as the kite. Further development was due to Ed Grauel and his "kite". The stability of the kite here has been further improved by the introduction of cells. Then Nick Morse finally developed Parasled based on it, in which the usual longitudinal rods were replaced with cells, as in Parafoil.

If you line up two of these parasleighs, you will get a "double parasleigh".

Unfortunately, the increase in kite again weakened the design without rods. A total of six longitudinal bars (4mm CFRP) are required to keep the kite stable. In addition, rods (GRP 2 mm thick) may be required to protect the two outer cells and the walls of the middle cell from destruction.

This building plan is a smaller version of John Verhey's plan, with a total area of approximately 3.5 m².

The original plan has about 15 m². If you multiply all the measurements in the plan below by 2.1153846, you get the original measurements. The 4 mm thick CFRP frame must be replaced with a 6 mm thick CFRP frame.

Design Notes:

Which parts you attach rod pocket attachments to is a matter of taste. Instead of pocket allowances, John Verhey sewed separate folded strips into matching seams as pockets.

The original plan also included rods for the keels in order to more evenly distribute the tension of the scales over the fabric (detail A: dotted line on x (length 56 cm). In my experience, you can do without them with the available size of the kite. In principle, it applies following

: As few rods as possible Which longitudinal rods can be excluded, for example, depends on local wind conditions.

A : Kiele (3x) The 129 cm side gets a 1 cm seam allowance. Reinforcing tape is sewn along the dotted lines to relieve the scale application. The remaining sides are hemmed with edging tape.

B : Outer chambers (2x) Two long sides receive 1cm seam allowances each. The two narrow sides are hemmed with edging tape. Under certain circumstances, a pocket may be required to insert a 2mm fiberglass rod into the longer of the two to keep the cell open in high winds.

C : Inner cell wall (3x) The two narrow sides are covered with edge tape. two long sides receive 1 cm seam allowances.

D : Chamber top walls (4x) The two narrow sides are lined with edging tape. The two long sides receive 1 cm seam allowances.

E : Chamber bottom walls (4x) The two narrow sides are covered with piping tape. two long sides receive 1 cm seam allowances.

F : Sail trims (2 pcs.) The two narrow sides are trimmed with edging tape. two long sides receive 1 cm seam allowances.

Three bridles are about 2-3 m long, the middle bridle is slightly longer.
