Diomedes developed a lightweight low-pressure hydraulic actuator made from a
carbon fibre cylinder lined with a high wear resistant gel coat. A light,
high force lockable actuator was needed for sweep actuation of the Exulans
outer wing sections. The expertise on working with composite materials led
to the decision to develop a set of actuators made from carbon fibre.
Endurance tests done on a test cylinder produced very favourable results.
