Description
Diamond, Eddy or Malay Kites are suitable for light to moderate breezes
Some general proportions and a basic method of construction is shown opposite.
Note: Once you have finalised your Kite proportions, the Angle of Attack can be set by adjustment of the Bridle. The normal method is to loop the Bridle over one finger and suspend the Kite upside down. The position of the finger is adjusted until the tail of the Kite hangs at an angle of 200 to 300 to the floor.
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)
- Almost all other dimensions are derived as a Percentage of the Spine Length (e.g the total Width is set initally as equal to the Spine Length - or 100%).
- 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 square Diamond increase the BridleTop to 50% - but you would then have to experiment to find a new top anchor for the Bridle)
Diamond Kite Examples
- In May 1891, William Eddy attached Malayan kites together to gain the height needed for weather measurements.
- In 1942, US Navy Commander Paul Garber develops a controllable diamond kite to provide targets for gun practice.
