Smartflyer is developing a hybrid-electric aircraft designed to make flying quieter, cleaner, and more efficient. Unlike traditional planes, our aircraft combines an electric motor with a fuel-powered range extender, reducing noise by up to 60% and CO₂ emissions by over 50%. It’s built for everyday use in pilot training, eco-tourism, and regional mobility—where sustainability is urgently needed. With a range of over 800 km and seating for four, Smartflyer offers a practical and certifiable solution for the general aviation market. Its modular design allows for easy maintenance, upgrades, and future integration of alternative power sources such as hydrogen or fully electric systems. The highly efficient rear-mounted propeller, positioned in a pusher configuration, minimizes aerodynamic drag and cabin noise while maximizing overall propulsion efficiency.
