   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Johan Humla; Samuel Friman; [2023]
   Keywords : ;

   Abstract : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. READ MORE

   Abstract : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. READ MORE

5. 4. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.

   University essay from Mälardalens högskola/Framtidens energi

   Author : Yash Khanna; [2019]
   Keywords : Hybrid electric aircraft system; Thermal management system; micro channel; Dynamic modelling; Mobil Jet Oil II;

   Abstract : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Swarna Manjari Ayyalasomayajula; [2018]
   Keywords : ;

   Abstract : To meet the demands to reduce national energy consumption and greenhouse gas emission targets based on environmental policy, the Ministry of Trade, Industry, and Energy of Korea formed a research consortium consisting of government agencies and academic research institutions to establish the first fuel efficiency standards for Heavy-duty commercial vehicles (HDV). The standards are expected to be introduced at the earliest in 2020 as Phase 1 of the plan. READ MORE
