A digital 'mule' for hydraulic systems testing

FlyTek HPU features touchscreen, remote troubleshooting and more.

BROOKHAVEN, Pa., - Aircraft maintenance technicians (AMT) can appreciate that FlyTek GSE hydraulic power units (HPUs) are designed with their work in mind. The job of the HPU, sometimes referred to as a “mule,” is to provide auxiliary power to an aircraft for the purpose of maintaining and repairing the aircraft’s hydraulic systems, AviationPros reports. Continue reading original article.

The Military & Aerospace Electronics take:

17 May 2023 - The HPU provides a source of pressurized hydraulic fluid. The unit filters, cools and supplies hydraulic oil under steady pressure to test the hydraulic systems of an aircraft without having to start the engines. These systems include landing gear, brakes, flaps, gear swings, thrust reversers and flight controls.

When operating the HPU, an operator can specify pressure and flow rate. All FlyTek HPUs are fully digital. A one-touch digital display replaces knobs and dials with an intuitive, user-friendly interface. Using the touchscreen, an operator enters the desired pressure and flow.

The HPU is a self-contained unit – no laptops or other devices are required, but because the HPU is Wi-Fi enabled, it can be controlled remotely with a tablet or phone.

“Our customers have used this feature to eliminate the need for personnel to go back and forth between the cockpit to do gear swings while changing pressure and flow remotely for various functions,” FlyTek Business Manager Junaid (Jay) Mukhtar said.
