  1. 1. 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.

  2. 2. Integrated generator for use in aircraft engines

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Fredrik Andersson; [2018]
    Keywords : Integrated generator; aircraft engine; generator; aircraft generator; Technology and Engineering;

    Abstract : In this paper the use of integrated generators for airplane engines is examined. In order to accomplish this goal a combination of MatLab with FEMM and ANSYS Maxwell is used to make incrementally more and more detailed analysis of the integrated generator concept. READ MORE

  4. 4. The Initial Deployment of Electric Vehicle Service Equipment : Case study: Green Highway Region, E14 from Sundsvall in Sweden to Trondheim in Norway

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : Iran Daniali; [2015]
    Keywords : alternative fuel vehicle; charging infrastructure deployment; gasoline stations; Green Highway; Electric Vehicle Service Equipment;

    Abstract : Abstract Electric Vehicles (EVs) are considered a more sustainable alternative vehicle because of their efficient electric motor when compared to internal combustion engines (ICE), and thus help to mitigate environmental problems and reduce fossil fuel dependency. In or-der to support drivers of plug-in hybrid electrical vehicles (PEVs), the installation and adequate distribution of Electric Vehicle Service Equipment (EVSE) is a major factor. READ MORE

  5. 5. Experimental Comparison of Losses in a Grid-connected and M2C-fed 11kW Induction Motor

    University essay from KTH/Elektrisk energiomvandling
