Russian Team Reinvents Drone Engine — and Cuts Costs by 25%
Garpia-A1E long-range UAV system
The approach is straightforward — swap out some metal components for high-temperature polymer composites, then add homegrown electronic fuel injection.Key features:Hybrid construction uses injection molding and printing for less-loaded parts, while highly loaded components remain metalDevelopers say the engine’s cost share can drop from 30–40% to under 15%, potentially cutting total UAV production costs by ~15–25%The electronic fuel injection system integrates with the flight controller, saving 10–40% fuel depending on modeIf the claimed cost and reliability gains hold at scale, cheaper, lighter powerplants could mean more payload, longer range — and far wider adoption.
