  1. 1. Dynamic response of damped attachments in fighter applications

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

    Author : Katja Nordström; [2023]
    Keywords : Vibration isolator; printed circuit board; vibrations; natural frequency; Vibrationsisolator; kretskort; vibrationer; resonansfrekvenser;

    Abstract : This thesis investigates the impact of vibration isolators on circuit boards during harsh vibrationenvironments that occur when they are mounted on the wings of a fighter jet. To examine thisphenomenon, a mathematical model and a simulated model were developed to determine theresonant frequencies of the circuit board under various boundary conditions. READ MORE

  3. 2. States and Prospects of Hydrogen Storage Technologies in Aircraft Applications

    University essay from KTH/Energiteknik

    Author : Kenzo Franzén; Fredrik Jangelind; [2021]
    Keywords : ;

    Abstract : In recent years, more than 100 000 commercial flights have departed daily, and the number of passengers worldwide are expected to double within the next two decades, assuming there are no long-term impacts of the Covid-19 pandemic. Meanwhile, the aviation industry will need to undergo a shift to more sustainable fuels, due to the growing issue of climate change and implementation of policies that regulate the use of fossil-based fuels such as kerosene.

  4. 3. Sustainability assessment of composites in aero-engine components

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Pauline Léonard; [2019]
    Keywords : Composites; composite; sustainability; sustainable; aero-engine; aero-engines; jet engine; aerospace; aircraft; aviation; environment; environmental; economic; social; titanium; aluminum;

    Abstract : Environmental issues such as climate change are leading to important sustainability challenges in the aerospace industry. Composites are light materials that are extensively used to replace metals and reduce the aircraft weight, the goal being to decrease the fuel consumption in flight and limit the emission of greenhouse gases.

  5. 4. Performance Assessment of Electrical Motor for Electric Aircraft Propulsion Applications : Evaluation of the Permanent Magnet Motor and its Limitations in Aircraft Propulsion

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Mathias Beckman; Alex Christy Gerald Volden; [2019]
    Keywords : Electric Aircraft; Permanent Magnet Electrical Motor; Losses; Hybrid-Electric Propulsion System; Environment; Global Warming; Aircraft Emission;

    Abstract : This thesis project will evaluate which kind of electrical motor is best suited for aircraft propulsion and which parameters effect the efficiency. An economic analysis was conducted, comparing the fuel price (Jet A1) for a gas turbine and the electricity price for an electric motor of 1MW. READ MORE

  6. 5. µHDS system for desulfurization of logistic fuels for fuel cell applications

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Johan Karstensson; Nicklas Jönsson; [2016]
    Keywords : Jet fuel; DBT; thiophene; HDS; catalysis; kemiteknik; chemical engineering; Jet A1; Technology and Engineering;

    Abstract : Logistic fuels such as diesel and petrol, in which Jet A1 is included, are sulfur-containing fuels used for transports. The main problem with logistic fuels, when used in fuel cell (FC) applications, is their relatively high concentration of sulfur compounds. READ MORE
