Find out the special features of our systems.
The boxplane structure with a truss-like airframe maximizes rigidity while minimizing weight. The two wings increase the power density, allowing economically viability even at small system sizes.
Each wing—top and bottom—has multiple control surfaces used to steer the kite.
The empennage features passive stability means, allowing stable flight even in gusty winds.
The truss-like structure is reinforced by diagonal bracings—a lightweight solution.
The non-tapered design of our wings allows production by aluminum extrusion. This method is very cost-effective and highly scalable.
The outer surface of the wings is made of extruded aluminum.
This airfoil configuration generates a very high lift and thus enables a very high power density.
Eight on-board electrical machines are used as motors during take-off and landing. The same machines are used as generators during figure eight flight.
Power electronics control the electrical machines dynamically to stabilize the kite and generate power efficiently.
Rugged brushless DC motor/generator for reliability, longevity, and high efficiency.
Fixed pitch, carbon fiber rotor blades which are optimized for maximum power generation at minimum noise.
A single point attachment enables full roll control freedom of the kite for optimum power harvesting efficiency and stability. The electro-mechanical tether consists of a Kevlar core acting as mechanical load carrier and electrical cables spiraling around the core.
Compact attachment point of tether with integrated sensors.
Fully redundant high voltage DC power transmission.
We can rely on various industry experts for components of our systems, ranging from motion tracking hardware over extrusion manufacturing to
rotor manufacturing and energy storage systems.
