Tetrahedral Kite Information

up Back to Kite Workshop

Tetrahredals are an interesting design for a kite. You have lots of scope to expore, and you can build really really large and different kites without changing your basic design.

The kite is a geometrical frame which is covered by sail. The geometry however has a number of pluses and minues. On the plus side is that the kite is cellular and can be expanded easilly just by tacking on more cells, it is also a very strong ridged structure, meaning you can use very light and flimsy materials. On the minus side its large number of spars make the kite heavy, and it is difficult to create a colapsible version for transport, or could take a lot of time for setup and put away.

These pages are my plans and note for tetrahedral kites. Enjoy.

You can some of the construction photos of my new 34 Cell Tetrahedral. It is built using a complete sparring structure, using plastic vinal tube joints cable tied together. The spars are 30cm, 3mm carbon fibre rods, and the cells covered with aluminized mylar and scotch tape.

60 joints, and 204 spars, for 34 cells.

[photo] STOP PRESS: A a class of fourth grade students in Bakersfield, California, made a 100 cell tetrahedral using straws and brightly coloured tissue paper. You can see photos of the final construction and results of this effort. Congradulations a job well done.
