Learnings from Rolls‐Royce hybrid propulsion systems in flight testing of High Power, High Scalability Hybrid Powertrain aircraft

This article describes the collaborative efforts between Tecnam, Rolls-Royce, and Rotax to equip a 4-seat Tecnam P2010 aircraft with parallel hybrid-electric powertrain, first of its kind ever developed for general aviation, help reduce fuel consumption while maintaining, even extending, range. The High Power, Scalability Hybrid Powertrain project set out design, build, ground-test demonstrate in flight campaign such propulsion system. Creating drive system, which brings together electric combustion engine worlds, creates completely new challenges assembly, operation, safety assurance must be addressed successful business proposition. reflects on some faced as this innovative scalable powertrain was road minimise emissions aviation industry.
