In Montreal, Canada, CAE is working on an innovative project to convert Piper Archer trainer aircraft to battery-electric propulsion. This initiative is driven by the company's goal to reduce carbon emissions and operating costs. The laboratory in Montreal houses several Piper Archer aircraft in different states of assembly, with engineers dedicated to the conversion project. The team is currently in the detailed design stage, aiming to deliver the first flight test vehicle in the coming months. The conversion process involves removing the combustion engine, modifying the wings' structure to accommodate batteries, and integrating the new engine and propeller. The project utilizes a Safran Engineus motor, with rigorous testing conducted for both mechanical and electrical performance. Challenges include uncertainties in the regulatory framework for battery-electric aircraft and constraints in the supply chain for parts. The team is also focused on developing a conversion kit that aligns with evolving regulations and safety standards. As the team navigates the complexities of adapting aircraft design to accommodate electric propulsion, the project highlights the importance of sustainability in aviation. By converting training aircraft to electric power, CAE aims to set a precedent for environmentally conscious practices in the aviation industry. The laboratory in Montreal serves as a hub for innovation, where engineers are pushing boundaries to create a certified conversion kit that can benefit the wider market. Despite the challenges posed by regulatory uncertainties and supply chain limitations, the project signifies a positive step towards sustainable aviation practices and technological advancement in the field.
