1. 1. Evaluation of electric actuation for fighter aircraft

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
   Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

   Abstract : 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. READ MORE

3. 2. Weight prediction of flight control subsystem

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Joel Lundahl; [2022]
   Keywords : Aeronautical engineering; aircraft; fighter jet; flight control system; FCS; weight prediction; early weight prediction; hydraulic system; control surfaces; actuator; subsystem; weight estimation; Flygteknik; flygplan; militärflygplan; stridsflygplan; styrsystem; viktprediktering; tidig viktprediktering; hydraulsystem; styrroder; styraktuatorer; aktuator; delsystem; viktuppskattning; metod;

   Abstract : 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. READ MORE

4. 3. Fault Detection in Permanent Magnet Synchronous Motors using Machine Learning

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Alexander Lennartsson; Martina Blomberg; [2021]
   Keywords : PMSM; Fault Detection; AI; artificial intelligence; Machine Learning; inter turn short circuit; inter turn short fault; turn-to-turn; permanent magnet synchronous motor; short circuit; fault; avionics; airplane; aircraft;

   Abstract : 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. READ MORE

5. 4. Digital hydraulic actuator for flight control

   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

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

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Simon Ward; [2017]
   Keywords : dha; digital hydraulics; hydraulics; aircraft; actuation; aircraft actuation;

   Abstract : 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. READ MORE
