Connect it to an existing fuel tank or opt for FusionFlight’s custom fuel tank solution for seamless integration.
Modular
Boost power output by connecting multiple ARC units in parallel, thanks to its block-like form-factor. FusionFlight offers customizable exhaust and inlet systems for diverse applications. Flexible mounting options allow the ARC micro turbine generator to be installed precisely where needed.
Versatile
The ARC micro turbine generator supports a range of heavy fuels, including Diesel, Kerosene, and Jet-A. Equipped with a built-in startup battery and self-recharge circuitry, it offers flexible integration. Customize the ARC with options like 3-Phase AC output or adjustable high-voltage DC output (250V-750V).

Micro Turbine Generator Applications

Engine Start-up
Power up large diesel engines and turbines with ease using the ARC micro turbine generator. This lightweight auxiliary power unit (APU) delivers a significant burst of power, making it ideal for starting heavy machinery and vehicles efficiently.

Range Extension
Extend the range of robots, ground vehicles, or sea vessels with the ARC generator. This compact diesel range extender recharges large lithium batteries on the go, offering a lightweight solution for continuous operation without heavy battery packs.

Emergency Power
When natural disasters disrupt the electrical grid, the ARC micro turbine generator provides reliable emergency power. Portable and lightweight, a single person can carry two ARC units, delivering critical power where large equipment can’t reach.

Hybrid Propulsion
The ARC generator revolutionizes hybrid-electric drones with its 18lb (8kg) stripped-down design. Easily integrated, it provides electrical power and bonus thrust from exhaust ports, enhancing lift and efficiency for advanced aerial platforms.
Case Study: Tripling Drone Endurance with Hybrid Propulsion
Hybrid Propulsion Advantage
Hybrid technology is revolutionizing electric VTOL drones, extending flight times far beyond traditional battery systems. The ARC micro turbine generator triples drone endurance with its lightweight design and high energy output, enabling longer missions for advanced aerial applications. Despite a 6% fuel-to-electricity conversion efficiency, the ARC generator’s low mass transforms drone performance. Ultimately, the superior energy density of diesel compared to lithium-polymer batteries overcomes efficiency limitations, more than tripling energy content, boosting endurance, and significantly extending flight time.
The Numbers Tell the Story
Battery Energy Density
A lithium polymer battery provides 89.9 watt-hours per pound (Wh/lb). For a 50.7 lb battery, the total energy stored is 50.7 lb × 89.9 Wh/lb = 4,557.93 Wh.
Hybrid Energy Density
Diesel fuel offers 5,272.5 Wh/lb. With the ARC’s 6% efficiency, the effective energy density is 316.4 Wh/lb. For a 48.3 lb generator/fuel-tank combo, the total energy stored is 48.3 lb × 316.4 Wh/lb = 15,282.12 Wh—3.5 times higher.

Easy Setup Guide
Quickly install the ARC system as a standalone unit or integrate it into your existing setup for dependable energy.

Mount the Unit
Position the compact generator on a flat surface or secure it within your system’s frame. Its vibration-free design ensures easy installation with flexible mounting options.

Connect Lines
Link two electrical wires (+/-) to your load and two fuel lines (supply/return) to a fuel tank. The integrated auto-priming feature simplifies setup for initial operation.

Activate the System
Flip the switch on the included remote control to activate the power system. The ARC will perform an auto-start procedure, after which you can select Manual or Auto mode depending on the firmware.
Operation Modes
Easily switch between Manual and Auto modes via firmware updates to suit your power requirements.

Manual Mode
Adjust the voltage output manually using the control knob, and the ARC system maintains desired voltage output under diverse load conditions.

Auto Mode
The ARC system automatically adjusts to a preset voltage and consistently delivers power at this level for reliable operation.
Technical Information.
The team at FusionFlight has leveraged over eight years of experience working on microturbine engines to provide a revolutionary new product in the field of turbomachinery. We strongly believe in design simplicity. The result is the ARC generator - a powerful and lightweight power-pack.

HARDWARE
At the heart of the ARC generator is the microturbine – a miniature jet-engine the size of a “soda can” that spins at rates up to 140,000RPM. A high-precision, fuel cooled gearbox takes power from a secondary turbine wheel and reduces this RPM further to 10,000RPM maximum. Waste gas leaves through a dual exhaust system.
-
ELECTRONICS
The device employs a dual-computer system. The system processes commands from a wired remote control (included with all kits) and other sensors inside. It ensures healthy and consistent operation of the device. A built-in battery allows many system starts and is actively re-charged during device operation.
-
SOFTWARE
All ARC units come pre-programmed from the factory ready to use out-of-the-box. Customers wishing to optimize the device for their specific application can take advantage of Arduino IDE to reprogram the firmware. The ARC is highly customizable and can accommodate a variety of communication protocols.

Advantages of the Micro Turbine Generator.
The ARC Generator has several advantages over similar-power combustion-based generators.
-
LOW EMISSION
The combustion process inside the turbine follows a completely different thermal cycle as opposed to the piston engine. This combustion process occurs at a lower-temperature and pressure and thereby produces less harmful gases.
-
LOW VIBRATION
The combustion inside the turbine is a steady-state process as opposed to the pulsed explosions inside the piston engine. At full throttle, the ARC is as solid as a brick ideal for applications requiring minimum vibration.
-
ROBUST
The centrifugal compressor within the ARC provides a reliable supply of air during varying ambient conditions. As a result, the ARC will work well in different environments and altitudes.
