1. Evaluation of electric actuation for fighter aircraft
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. LÄS MER
2. Weight prediction of flight control subsystem
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. LÄS MER
3. Fault Detection in Permanent Magnet Synchronous Motors using Machine Learning
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : In the aviation industry, safety and robustness are the number one priorities, which is why they use well-tested systems such as hydraulic actuators. However, drawbacks such as high weight and maintenance have pushed the industry toward newer, electrical, actuators that are more efficient and lighter. LÄS MER
4. Digital hydraulic actuator for flight control
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : 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
5. Digital hydraulics in aircraft control surface actuation : Modelling and evaluation of digital hydraulic systems with focus on performance and energy efficiency
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : 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
