What is it about?
Typically, an electric motor is efficient at high rate but inefficient in holding a standing load or accelerating it’s own inertia. Conversely, hydraulic systems can hold load and accelerate with minimal loss, but suffer throttling losses at rate. Together with Domin, we are working on the development a way of creating the benefits of both by using a combination of fast, low loss control valves, together with a dual displacement pump. The innovative design features electrically signalled and powered actuator with the hydrolic power capabilities and hydraulic regeneration when the commanded movement is aligned with the direction of external force. This new feature helps to incease performance and decrease energy consumption.

Why is it important?
The commitment of airlines to achieve net zero carbon by 2050 is a quite challenging task. One of the key steps in this route is the development of electrically powered servos that meet or exceed the performance, packaging, weight, and cost of a hydraulic fly-by-wire servo.
Perspectives
I am hoping that this research will help to make aviation greener.
