Electric UAVs have made significant progress in recent years, especially in small-scale applications. However, when it comes to range, endurance, and payload, battery-powered systems continue to face fundamental limitations.
Energy density remains the key factor: liquid fuels still provide a clear advantage over batteries in long-endurance missions. This directly impacts flight time, operational flexibility, and mission capability.
For long-range applications such as ISR, maritime surveillance, BVLOS operations, or critical infrastructure monitoring, internal combustion engines continue to play a central role.
Hybrid concepts are further expanding this role, combining electrical efficiency with combustion-based endurance.
Our latest paper explores why combustion engines remain essential for long-range UAV architectures and how modern propulsion concepts are evolving.
