Prototype Developments

We focus on quick iterations and creating simple prototypes that ideally only introduces a few new concepts in iteration. Here the main results are presented.

Autonomous looping

August 24th Finally completed full autonomous looping in crosswind flight. We still need to do a few more tweaks for the control algorithm, but soon we can move on to dual kite testig. Video: Autonomous looping with HUD

Physics simulation

July 19th To develop new control strategies and kite designs we have developed a new kite/drone physics simulation. Detailed description.

Upgrade transition algorithms

July 16th We decided to try and improve the robustness of our transition algorithm (from hovering to flying like a kite/plane in the wind) Video: Improved VTOL transition.

SuperQ Position Controlled Outdoor Hover

March 20th Our first autonomous flight in positional hover control mode. Position commands are send from our ground control software running on the laptop. The kite is aware of the tether point and takes any position commands and translate it into movement on the sphere of possible locations. Additional thrust in the direction of the tether towards the kite is added to keep a constant tether tension.

SuperQ Tethered Indoor flight

March 8th First successful tethered flight of our kite that will be able to take of and land like a drone. We are working on optimizing the flight control software before we continue with outdoor testing. Video clip

Fixed Wing Kite

November 1st We believe that fixed wing (or hard kites) will be the most economical form of airborne energy due to their better Lift to Drag ratios and higher longevity. We succeeded in creating a radio controlled flying fixed wing kite gaining valuable practical insights into the flight dynamics of such a system and construction techniques. detailed description Video clip

Autonomous Flight control

September 13th One of the key technologies need to master kite wind energy is the ability to develop an active control system that’s able to guide the kite autonomously following a given path. We succeesfully tested such a system with a two line soft-kite. The position was captured using a smartphone camera. detailed description Video clip
