GARDN II Projects (2014-2019)

Development of an Electric Propulsion System to Convert Gliders for Self-Launch Operations to Reduce the Environmental Footprint




Demonstrate that electric propulsion is feasible and viable to support glider launch operations with multiple flights per hour with quick battery replacement in-between flights, develop the Canadian expertise in electric propulsion for general aviation-sized aircraft, and increase awareness for green aviation through a project that is “accessible” to Canadian citizens.


The OPT-21 team has:


  • Demonstrated the feasibility of retrofitting a certified glider with an electric propulsion system for self-launch capabilities;
  • Proposed a certification basis for a certified electric glider in Canada;
  • Highlighted the certification challenges of electrical propulsion in Canada;
  • Increased the level of technical knowledge on the topic of electric propulsion units for the civil aviation sector in Canada;
  • Demonstrated the potential noise reduction to use an electrical powertrain in comparison with conventional internal combustion engine.
