LOW-NOISE ELECTRIC POWERTRAIN FOR GLIDER TRAINING OPERATION
Optis led an innovative project to explore the potential of electric propulsion to reduce flight training operations noise, emissions and cost. OPTIS partnered with the Université de Sherbrooke (10 students involved under Projet Zéphyr) and the Royal Air Cadets League to convert a certified glider into a fully integrated, self-launchable, electric-powered flight training platform. This project was made possible thanks to the support of the Green Aviation R&D Network (GARDN) under the OPT-21 project.
This projects demonstrated how electric propulsion could reduce noise during takeoff by as much as 11 dB: a significant improvement for citizens living nearby airports. This project also contributed to develop Canadian expertise in electric propulsion and paved the way to a better understanding of how these systems could be integrated into certified aircraft safely.
