Flygas highlights the GAS418HA (180hp), a supercharged four-stroke gasoline engine engineered for high-altitude and MALE (medium-altitude long-endurance) UAV applications.
Designed for Group 4 and Group 5 unmanned aerial systems, the GAS418HA delivers an impressive 180 HP at 5,800 RPM while maintaining an impressive power-to-weight ratio of 2.3 hp/kg, making it ideal for endurance missions in demanding environments.
The engine features a gear-driven centrifugal supercharger and forced-circulation water cooling, ensuring consistent performance across a wide altitude range. Flygas offers flexible configurations, including dual redundant EFI systems or a hybrid EFI and carburetor setup, plus optional secondary alternators to meet diverse platform requirements.
The GAS418HA is compact and lightweight, weighing only 78 kg (172 lbs), and measures 664 mm wide, 449 mm high, and 584 mm in depth from the propeller flange. Its four-cylinder opposed layout, paired with double spark-plug ignition and a robust dry or wet sump lubrication system, guarantees reliable operation and ease of integration. The engine also comes with a gearbox reduction system with shock absorption, supporting multiple ratios for optimized propeller performance.
Engineers and UAV operators seeking a high-performance propulsion solution for long-endurance, high-altitude missions will find the GAS418HA a versatile and dependable choice, combining advanced engineering with Flygas’s proven reliability.
Flygas will be exhibiting its engines, including the GAS418HA, at the 2026 Farnborough International Airshow, 20-24 July.
