Lowental Hybrid

Lowental Hybrid is the developer of the world’s first Native Parallel Hybrid™ propulsion system for UAVs (unmanned aerial vehicles). The company’s innovative solution is hybrid by design, combining an electrical system with an internal combustion engine to deliver high-speed fuel-powered flight and a low-noise stealth mode driven by battery.

The battle-proven system is ideal for Group 2 or 3 UAVs, providing massively enhanced flight endurance and covert capabilities with minimal integration requirements and no compromises.

Native Parallel Hybrid™ Technology

LGH-00_Lowental Hybrid propulsion Native Parallel Hybrid™ is the only propulsion architecture that has been designed from the ground up to combine the longevity advantages of ICE with the stealth capabilities of electric power on the same drivetrain. The engine recharges the battery on the fly, eliminating the need for battery swapping and boosting endurance by up to five times. Electric and combustion power can be operated independently or combined together, allowing you to switch instantly to adapt to changing mission profiles.

The solution is a true drop-in capability, providing enhanced effectiveness for your tactical drone platforms without the need for complete system overhaul or the purchase of an entirely new UAV.

Next-generation propulsion for tactical UAVs & loitering munitions

The LH Series is a family of versatile hybrid propulsion systems that has been designed for fixed-wing and VTOL UAV platforms. Delivering quiet and precise maneuvering for takeoff and landing and powerful fuel-efficient flight for long-range operations, it is ideal for a variety of use cases, including covert ISR and tactical loitering.

All units feature advanced built-in EFI (electronic fuel injection), ensuring optimal engine performance under a range of operating conditions. Seamless in-flight switching between gasoline and electric power allows you to lower your platform’s acoustic signature on demand, and also provides automatic failover and limp-home capabilities.

Other advantages of the LH Series of hybrid propulsion systems include:

No need to wait for battery recharging
Continuous reliable operation even under challenging weather conditions
Optimized power-to-weight
Boosted takeoff power for full torque when you need it most

The LH Series currently includes the LH-01 for fixed-wing UAVs weighing up to 25 kg. Lowental is actively developing additional products for MTOWs of up to 50 and 100 kg.
