Fuel Pump
Currawong manufactures lightweight, low-power, high-pressure fuel pumps specifically for use in the UAV industry. These high reliability fuel pumps significantly reduce fuel delivery problems typically associated with UAV engines. Currawong’s pumps are designed specifically to address issues which will be familiar to many airframe system integrators, such as SWaP, reliability and recovery from fuel pickup issues.

Self Priming
With outstanding self priming performance and the ability to run on air continuously, Currawong pumps allow an engine to recover gracefully from pickup loss or injection of air into the fuel supply lines. Watch the video below to see the superior performance of Currawong’s fuel pumps when the fuel line is removed.
Configurable
Currawong fuel pumps are extremely configurable – different gear head combinations can be specified to meet fuel pressure and flow rate requirements.
Reliable
Currawong pumps have completed endurance testing to more than 1,000 hours of continuous operation and the pumps are rated for 700 hours between service intervals.  The high reliability of the fuel pump reduces the airframe maintenance burden and provides added confidence in the fuel system.
Low Power
With very small power requirements (< 2W typically) these pumps are an excellent choice for extending the endurance of an aircraft. Additionally, running the pump in a tight pressure-regulation loop (as opposed to a dead-headed fuel rail) provides significant power savings as the pump spends a lot of time idle during the flight. Currawong’s Engine Control Unit (ECU) provides closed-loop fuel pressure control.
Single Cylinder Pumps
The ECU provides a complete single-supply solution, with integrated high-power injector and ignition drivers, servo control of throttle position, closed-loop fuel pump control and a 6V supply for use with throttle servos and ignition units. All sensors and control systems connect directly to the ECU, which even includes high-power drivers for added GPIO (General Purpose Input Output) ports.
Powerful Control Interface
Currawong’s miniature fuel pumps are designed for fuel flow rates up to 120 grams per minute. These pumps integrate directly with the Currawong ECU to provide tight pressure regulation with minimal power consumption and added weight. A range of configuration options are available. Currawong’s fuel pumps, although developed to provide a reliable fuel flow for EFI systems, have a wider range of applications than just for EFI. Conventional fuel systems using carburettors are susceptible to fuel flow interruptions arising from operation in a three dimensional environment and require positive displacement, self priming pumps to assure reliable fuel supply. Currawong’s US distributor, Power4Flight, discusses the merits of fuel pumps that have the positive displacement characteristics of Currawong’s products in the technical paper below.
