   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Robert Pettersson; [2018]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

4. 3. Digital hydraulics in aircraft control surface actuation : Modelling and evaluation of digital hydraulic systems with focus on performance and energy efficiency

   Sammanfattning : The purpose of this thesis has been to compare and analyse the use of digital hydraulic actuators in place of traditional actuators in aircraft control surface manipulation. Digital hydraulic actuator referring to a hydraulic actuator where the power has been discretized using discrete on/off-valves. LÄS MER
