Delta Kite Construction

Description

Delta Kites, like Hang Gliders, are based on Rogallo's flexible wing. They are suitable for moderate breezes.

Some general proportions and a basic method of construction is shown opposite.

Materials and Construction

Kites can be made quite successfully using thin Polyethylene sheeting (e.g. as used to make bin liners) and Adhesive Tapes, split Bamboo flower sticks. Kraft Paper can also be used and even Tissue Paper, especially for smaller Kites and using BBQ Skewers for Spars.

More sophisticated Kites, and most commercially available KItes, use Ripstop Nylon or similar, together with Fibreglass Rods and Tubes. Instead of fixing with tape, extra allowances are added to the Kite pattern where needed, to enable the Spars to be slotted into sewn hems.

Designer

• Click on the pencil-shaped Edit icon below to show or hide variables and click inside table to alter values (scroll to see all).
• Left or Right click on the screen display or use Scroll Wheel to alter view and Left click on Zoom icon to restore (note: Zoom will be focussed around the cursor position)
• Left click on Download icon and Open with your preferred browser then print screen image from there (useful for trying ideas for text and graphics etc. but unlikely to be actual size), or Save File to create a full-size Scalable Vector Graphics (svg) file which can be loaded into LibreOffice Draw and printed, or graphics software such as Inkscape for eventual output at actual size to a Plotter/Cutter for example. See Packaging Designer User Guide for more detail.

Note:

• The main variable in the table below is the total length of the Kite Spine (set initally to 1200mm)
• All other dimensions are derived as a Percentage of the Spine Length (e.g the total Width is set initally as twice the Spine Length - or 200%).
• All Percentages initially are based on the proportions given at the start of this article but all can be changed by clicking in the table and typing in a new Percentage (e.g. to make a more pointed Delta by reducing the Width)

Delta Kite Examples

• Hang gliders are based on the flexible kite wing designed in 1948 by Francis Rogallo, a NASA aeronautical engineer and in 1958 further developed by him into the 'parawing', a structure-less kite used to enable spacecraft to land.
