  1. 1. Electric Propulsion for a High Altitude Unmanned Aerial Vehicle

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jacob Hjort Friderichsen; David Jönsson; [2022]
    Keywords : Electric Propulsion; UAV; ALPHA; Electronic Speed Controller; BLDC Motor; Propeller;

    Abstract : The catalogue of observational platforms for space and atmospheric research can be expanded by utilising drones equipped with specialised instrumentation and capable of flying at high altitudes. In this project the requirements for an electric propulsion system applicable to the KTH Royal Institute of Technology ALPHA project are evaluated. READ MORE

  2. 2. Modelling & Analysis of a TiltWing Aircraft

    University essay from KTH/Flygdynamik

    Author : Felix Rubin; [2018]
    Keywords : ;

    Abstract : The aim of this report is the investigation of a hybrid vertical take-off and landing (VTOL) tilt wing aircraft which is in development at the company Dufour Aerospace. Using a model, programmed in MATLAB® different stages of flight can be simulated and investigated. READ MORE

  3. 3. What affects the VC spatial clustering in China? Research on determinants of location selection and VC performance

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Weijia Chen; [2018]
    Keywords : venture capital; spatial clustering; VC performance; location quotient;

    Abstract : As a key propeller for the economy development and technology industrialization, venture capital (VC) has attracted the attention of both academics and policy makers around the world. In China, the spatial distribution of VC industry exhibits a high degree of agglomeration: More than 60% of Chinese VC firms cluster in Beijing, Shanghai, Zhejiang and Guangdong and VC investment performance in these four provinces behaves significant better than other non VC clustering regions.

  4. 4. Modeling and Control of a Parallel HEV Powertrain with Focus on the Clutch

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

    Author : Mahdi Morsali; [2015]
    Keywords : parallel hybrid electric vehicles; clutch modeling; driveline modeling; torsional vibrations; slipping clutch; energy management; optimization;

    Abstract : Nowadays, the increasing amount of greenhouse gases and diminishing of the existing petroleum minerals for future generations, has led the automotive companies to think of producing vehicles with less emissions and fuel consumption. For this purpose, Hybrid Electric Vehicles (HEVs) have emerged in the recent decades. READ MORE

  5. 5. Thin metal patch to FRP propeller: Experimental testing of bonding systems

    University essay from KTH/Lättkonstruktioner

    Author : Mårten Kreiss Amberg; [2015]
    Keywords : ;

    Abstract : To enable the use of carbon fibre reinforced polymer (CFRP) propellers for merchant vessels, the problem of cavitation must be solved. The matrix of the FRP is generally brittle and more sensitive to cavitation erosion than the more conventional metal propeller blades. Nakashima Propeller Co. READ MORE
