Vehicle

ultra-lightweight flying wing aircraft for setting new flying records: non-stop operation / flying at an altitude of ~100,000 feet

Status

Passenger capacity

Size, weight

wingspan: 247 feet

Propulsion concept

Helios Prototype is based on the Centurion prototype and is powered by 14 electric motors (1.5 kWe each) mounted across the wing's entire span. The first prototype was powered by batteries in 1999. In 2000 more than 62,000 solar cells were installed upon the flight wing of the Helios prototype.The next planned prototype should be equipped with solar cells and fuel cell fuelled by an on-board generated hydro- and oxygen. A regenerative + non-regenerative fuel cell system has been developped
