Softkite Design

Softkites

As far as the construction is concerned, softkites are primarily derived from paragliders. Over many years, softkites were mainly implemented as traction kites for pulling buggies (three-wheeled vehicles), or used purely as fun kites.

Evolution

RGD™’s chief designer Ralf Grösel was a partner in founding the company Flysurfer GmbH in 2001, and he was responsible for an evolution in the designing of softkites. Through pioneering technical advancements, he managed to permanently extend the range of implementation of softkites onto water. Ralf Grösel is responsible for the model series “Speedair,” “Easyair,” “Mastair” and “Warrior.” Through a modification of the chambers and the installment of integrated fans, the softkite could operate as a closed system and keep inflowing air in the chambers, without allowing them to fill up with water. Self-stabilizing profiles, safety systems and systems for de-powering the flexible airfoils round up Ralf Grösel’s accomplishments in developing softkites, and all later became standard in their field.

Starting in 2003, RGD™ was entrusted with the construction and development work for the snowkite product area of the kite manufacturer North Kiteboarding. In close cooperation with three-time world champion snowkiter Fabio Ingrosso, these model series were brought to life:
-  Husky, Husky LTD
-  Fabio, Fabio Pro
-  07 SOLID, 08 SOLID and 09 SOLID.
The model Husky LTD was the first land and water kite that utilized only two levels of lines. This reduced line resistance provided for higher performance. The Fabio Pro allowed flight conditions and gliding phases that were previously reserved for paragliders. On the other hand, the SOLID series (beginning with the model year 2008) set new standards in the area of safety functions with its 5th-line safety system.

The Challenge

Through the flexible elements which are inflated by means of dynamic pressure, softkites are so-to-say small paragliders. However, they are significantly smaller and need to be more stable. Great demands are made upon both materials and construction. A multitude of variables that are difficult to calculate make softkite designing one of the greatest challenges in construction. In the past years, RGD™ has been able to oblige again and again with technical advancements and improvements. The combination of modern analysis and construction software with the comprehensive store of experience from more than 150 softkite and hybrid prototypes is the basis of RGD™’s success. Even before the manufacturing phase, new products can be developed into an exact price and target class. That is possible because of close cooperation with production workshops around the world, as well as a set cost target, which is agreed upon beforehand with the customer.
