  1. 1. Electrical Propulsion System Design of a Blended Wing Body UAV

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Kevin Azad; Felix Fungula; [2022]
    Keywords : Aerospace; Aviation; Blended Wing Body; Electrical; Green Raven; Propeller; Propulsion; UAV;

    Abstract : The conventional tube-and-wing aircraft has been around since the 1950s, with little to no innovative progress being made towards redesigning the conventional aircraft. The blended wing body (BWB) shape fuses the wing of the aircraft with the fuselage increasing structural strength while also increasing potential surface area to create lift, making it more efficient than conventional wing shapes.

  2. 2. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse

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

    Author : Adam Bussmann; [2022]
    Keywords : Hybrid; Hybrid propulsion; Hybrid propulsion system; System specific impulse;

    Abstract : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. READ MORE

  3. 3. A Component-based Model of a Fuel Cell Vehicle System

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Fordonssystem

    Abstract : Improving the efficiency and performance of vehicle propulsion systems has always been desirable, and with increasing environmental awareness this has become increasingly topical. A particularly strong focus today is at fossil-free alternatives, and there is a strong trend for electrification. READ MORE

  4. 4. Electrically powered manoeuvring of water jets

    University essay from Uppsala universitet/Industriell teknik

    Author : Joel Engström; [2021]
    Keywords : Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Abstract : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.
