Introducing the newest addition to their growing range, Currawong is releasing the Cortex
Heavy Fuel Hybrid System. As a series hybrid this engine system will take to the sky with industry leading power density, an innovative new fuel and features Currawong’s well-
developed power electronics.
The hybrid architecture allows the engine to provide power to onboard electrical systems and charge batteries while providing propulsion power for flight. Another feature is in the event of high-power requirements, the engine and the batteries work together to boost total power.
This also decreases overall weight of the power train by reducing the number of batteries
required to maintain flight durations. Power can also be directed from the battery system to
the engine for self-starting, power boost during flight and in-air engine restart.
In order to balance the flow of energy through the system Currawong designed a Hybrid
Transmuter based on the extremely power dense Velocity ESC range. The Hybrid Transmuter manages battery charging, changing load requirements of the UAV and determines whether to deliver power from the engine to the batteries or from the batteries to the engine. All this is handled automatically, making the Cortex system the ideal battery replacement.
Currawong engineers are always seeking ways to innovate and improve our products for the best performance. Heavy fuel, more specifically, a stable heavy fuel is invariably sought to create a safer environment for their workforce. Currawong has been able to show that UMAN-VP4F works well as a spark-ignited fuel in the Corvid-50 engine and burns with very clean combustion. The power output of the engine is comparable to that of petrol. UMAN-VP4F requires 8 to 10 bar of fuel pressure, ideal for the use of Currawong’s specialist Triplex fuel pump.
The Cortex System is the ideal for Naval applications due to this innovative fuel, the hybrid
nature of the engine extends the application across a varied range of vehicles.
