Efficiency Redefined: Klaus Ohlmann on the Future of Electric Flight

At the AERO Friedrichshafen aviation expo, world-record pilot Klaus Ohlmann, alongside Stefan Gorkenant and Stefan Senger, discussed one of the most exciting developments in modern aviation: the successful maiden flight and technology behind the E-Rob (a modified Antares 20E).

This video provides a fascinating, hands-on look at electric flight, demonstrating how combining aerodynamic perfection with innovative propulsion will revolutionize general aviation.

Key Highlights from the Presentation:

• Small Propeller, Massive Impact: Despite initial skepticism regarding the compact FES (Front Electric Sustainer) nose propeller (1.20 m diameter), the system delivered outstanding performance during its maiden flight in Augsburg. The aircraft lifted off after a takeoff roll of just 200 to 300 meters, achieving a strong climb rate of 2.5 m/s.

• Radical Energy Savings: The numbers speak for themselves. While the original Antares requires around 16 kW for level flight, the modified E-Rob variant with its optimized nose propulsion consumes just 6 kW. This represents a massive leap forward in pure electric range.

• Safety at the Flip of a Switch (The “Panic Button”): Instead of heavy, complex retractable engine pods, this system relies on the KISS principle (Keep it simple and stupid). Flip a switch, turn a dial—and full power is available within two seconds. This provides an invaluable safety margin when flying at low altitudes.

• The Future is Hybrid: Due to the laws of physics and battery weight, pure electric flight hits a ceiling at around 400 to 500 km. Klaus Ohlmann emphasizes that anyone aiming for true cross-country range in general aviation over the next 15 years must embrace highly efficient hybrid solutions (range extenders).
