1. 1. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Simone Guietti; [2024]
   Keywords : Pintle injector; space propulsion; space engineering;

   Abstract : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. READ MORE

3. 2. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   University essay from KTH/Mekatronik och inbyggda styrsystem

   Author : Arvid Bergvall; Pontus Lundman; [2023]
   Keywords : Mechatronics; Gantry; Stepper motor; Control; Linear Quadratic Regulator; Adaptive LQI; PID; Mekatronik; Gantry; Stegmotor; Reglerteknik; LQR; Adaptiv LQI; PID;

   Abstract : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. READ MORE

4. 3. Development of Elastic Mechanism for actuation of Valve

   University essay from KTH/Maskinkonstruktion

   Author : Nidhi Menon; [2023]
   Keywords : Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

   Abstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

5. 4. Design of a Bistable Origami Stent with Pneumatic Actuation

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

   Author : Michelle von Rosen; [2023]
   Keywords : ;

   Abstract : What if stents could be easier removed when complications arise or removed once theirjob has been done? No matter how perfect a stent design becomes, the fundamental issueis that a foreign object in the body under extended periods eventually will cause devicedegradation and complications. So instead of making a long-term solution of a perfectstent, the focus in this paper is redirected from expensive materials to a simple design,with simple materials. READ MORE

6. 5. 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
