The Electric Aircraft Elektra One, developed by Calin Gologan, performed its first internal flight on Saturday, 19 March 2011 at the Augsburg Airport in Germany.
During its maiden flight, the noise free Elektra One climbed to over 500 meters, using 3 kWh of energy from the total 6 kWh available on board.
"Our expectations have been exceeded", says Calin Gologan, CEO of PC-Aero GmbH in Germany. "We are overjoyed."
The Geiger Engineering Company, also located in Germany, developed the electric drive unit including electric motor HPD 13.5 (16kW maximum power), controller, battery management and propeller.
"We do not have to wait for new technologies, we only need to integrate current components (lightweight structures with high-quality aerodynamics, light and modern electric motors and batteries) in an optimized system. With the ELEKTRA ONE and the existing technology it is possible to fly electric without CO2-emission and noise for over three hours. In addition, in comparison to a classic aircraft, the operating costs are much lower", says Gologan. "This is very interesting for flying clubs."
The aircraft can achieve a range of over 400km and cruise at 160km/h with operating costs below 35 €/hour and 0.2 €/km - the total system including aircraft, hangar and power costing less than 100,000 euros.
- number of seats: 1
- maximum weight: 300 kg
- wingspan: 8,6 m
- wing surface : 6,4 m2
- maximum engine power: 16 KW
- empty weight (without batteries): 100 kg
- max. batteries: 100 kg
- payload: 100 kg
- max. range: over 400 km
- max. endurance: over 3 hours
- modern composite glass-/carbon-structure
- advanced aerodynamic design
- best propeller efficiency (90%)
- light batteries
- highly efficient electric drive
- integration of new certification procedures
The aircraft is powered with 20 m² of photovoltaic-cells on the hangar roof at a cost of 6000 euros which is amortized over 8 years, making it completely independent of the national grid. Although the aircraft is aimed at the aviation sport and leisure industry, the company believe the aircraft will benefit developing countries where electricity is limited.
The next step for the team is to participate in the NASA-/CAFE- Green Flight Challenge 2011 being held 11-17 July, 2011 in California, USA. The aircraft must fly 200 miles in less than two hours using the energy equivalent of less than 1 gallon of gasoline per occupant.
