Gemini’s unique two-opposed-pistons-per-cylinder design offers a number of advantages for aviation applications:

  • Green operation with much lower emissions
  • Runs on Jet A, diesel or bio-diesel fuels
  • Highly efficient two-stroke operation
  • Up to 20% lower fuel burn than avgas piston engines*
  • Lighter weight with higher torque at lower RPMs
  • Mechanically simpler design with fewer moving parts
  • Retrofittable with many current piston engine designs
  • Modular design simplifies model growth
