GAS418HA

The GAS418HA is a high-performance four-stroke gasoline UAV engine that delivers 180HP output at 5800 RPM, with an excellent power-to-weight ratio of up to 2.3 hp/kg. Featuring a gear-driven centrifugal supercharger, it can be easily installed into a wide range of platforms.

The engine can be provided with dual redundant EFI systems, or with a EFI and carburetor configuration. It can also be supplied with a secondary alternator upon request.

GAS418S

The GAS418S is a highly compact four-stroke gasoline engine that is designed to fit into very small UAV fuselages. Ideal for medium to high altitude applications, it is suited to both fixed-wing and unmanned helicopter platforms, delivering specific power of up to 2.31 hp/kg.

Built around a mechanically-driven centrifugal supercharger, it features completely ECU-controlled fuel injection and ignition, ensuring optimum performance under a wide range of environmental conditions. The versatile engine can be installed in either horizontal or vertical axis configurations.

GAS418A

The GAS418A is a 1.8-liter, four-stroke Otto-cycle boxer engine designed to deliver dependable propulsion for MALE unmanned aircraft. It produces up to 100 kW (135 hp) at 5,800 RPM (sea level) with a power-to-weight ratio of 1.8 hp/kg, and is available in horizontal (75 kg dry) or vertical (80 kg dry) installation configurations to suit different airframe layouts.

Fuel delivery is handled by electronic fuel injection via an EFI Technology Euro 2 ECU with CAN bus 2.0B connectivity, with an optional EFI + carburetor variant available on request for added fuel-system redundancy.

Flygas 912 EFI Supercharged Engine

We supply the brand new Rotax 912 ULS engine completely assembled, bench tested and equipped with the following Flygas kits:

• Supercharger for Rotax 912 – 142 HP
• Redundant Electronic Fuel Injection “Fly-Safe” with Carburetors
• Mechanical Fuel Pump 3 bar

More power, less additional weight, increased load capacity.

Centrifugal Supercharger

Our centrifugal supercharger for Rotax 912 series engines provides maximum power of 110KW (150hp) at 5800 RPM, with low installation weight and an oil supply that is completely separate from the engine oil. It delivers an excellent power-to-weight ratio of up to 2.3 hp/kg, with very low exhaust temperatures compared to turbocharged engines.

The supercharger can be provided with dual redundant EFI systems, or with a EFI and carburetor configuration.

Electronic Fuel Injection System

Our patented EFI system is designed to provide Rotax 912 series engines with enhanced engine capabilities and lower operational costs, and can be customized to specific UAV requirements. The system runs parallel to the carburetor, and provides a critical redundancy in case of failure.

The EFI system is fully calibrated to provide the optimal air-fuel mixture under all power delivery conditions. It ensures vibration-free operation, and also removes the possibility of detonation in the supercharged engine at lean stoichiometric ratios.

Mechanical Fuel Pump

Our mechanical fuel pump delivers fuel at pressures between 1 and 3 bar, with a flow rate of 150 liters/hour at 3 bar. Designed to operate independently of the 12V system, it conserves electrical energy and ensures continued reliable operation even after electrical failure or in the face of EMI.

Weighing approximately 500g, the compact pump can be installed on a wide variety of tactical UAV engines, and we can create custom mounts to suit your exact requirements. Ready-to-install kits are already available for Rotax 914 Turbo engines.

Thanks to its high level of torque, the mechanical pump is less prone to stoppages due to dirt and debris, and avoids the issues associated with the input filters found in electric pumps. Due to the flow being directly linked to the engine RPM and thus being zero at rest, the design also provides enhanced fire safety.
