   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Felix Larsson; Christian Johansson; [2019]
   Keywords : DHA; Digital hydraulics; Flight actuation; Actuation; Digital Hydraulic Actuator;

   Abstract : In aviation industry, one of the most important aspects is weight savings. This since with a lowered weight, the performance of the aircraft can be increased together with increased fuel savings and thus lowered running costs. READ MORE

3. 2. Safety analysis on digital hydraulics : Redundancy study for aviation applications

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Robert Pettersson; [2018]
   Keywords : ;

   Abstract : Digital hydraulic actuators (DHA) are an interesting new technology that couldreplace todays system with inefficient proportional valves. By using an arrayof on/off valves the hydraulic pressures are discretised. This gives a fixed setof force outputs that can be used to control the actuator. READ MORE
