Breaking Boundaries: Vira Drones and Wankel Supertek Redefine Powerplant Units for VTOL Applications

Today marks yet another milestone for Vira Drones as we continue to innovate and push the boundaries of drone technology. Teaming up with Wankel Supertek, we have successfully designed a powerplant unit capable of running on natural gas. This creation is based on the groundbreaking Wankel KKM503 engine, ingeniously redesigned by our team for vertical installation for use in Vertical Takeoff and Landing (VTOL) applications.

The KKM500 series engines from Wankel are highly interesting in the industry for their unique attributes:
  • High power to weight ratio
  • Low vibrations
  • Extended life-expectancy
  • Easy maintenance
  • Cost-effectiveness
  • Compact design
  • Low production costs
  • Turbocharged capabilities
  • Configurable from single-rotor up to 4 rotors
  • Hybrid propulsion systems

They come in a standard configuration, based on diesel fuel, but they also have the adaptability to function on both hydrogen and natural gas.

In terms of performance, the KKM500 series engines provide 22 – 160 kW power output at 3000 – 6000min-1. They offer the best fuel consumption when used with diesel-fuel with a density of 0.835 kg/dm3 at 15°C.

Our cooperative work with Wankel Supertek has enabled us to leverage the strengths of the KKM503 engine, enhancing it further for vertical installation in VTOL applications. This redesigned powerplant unit with its compatibility for natural gas paves the way for more sustainable and cost-effective solutions in the drone industry.

We are looking forward to the new horizons that this innovative powerplant unit will open up. Stay tuned as we continue to redefine drone technology and push the boundaries of what's possible.
