  1. 11. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Belén Alonso Rancurel; [2023]
    Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

    Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.

  4. 13. Sensorless Control of Synchronous Machines in Python Using Signal Injection : An implementation of a High-Frequency Square-Wave Injection Algorithm on a Linear and Non-Linear Synchronous Machine Model in open-source Software Motulator

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

    Author : Simon Lundberg; [2022]
    Keywords : High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Abstract : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. READ MORE

  5. 14. 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.
