  1. 1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    University essay from KTH/Kraft- och värmeteknologi

    Author : David Fredouelle; [2023]
    Keywords : Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Abstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions.

  3. 2. Improving Aircraft Fuel Consumption Prediction through Ensemble Learning

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

    Author : Hanlin Gongzhang; [2022]
    Keywords : Aeronautics; Commercial Aircraft; Aircraft fuel consumption; Flight data; Aircraft performance model; Aircraft fuel consumption modelling; Weighted average ensemble; Machine learning; Flygteknik; Kommersiellt flyg; Flygplanens bränsleförbrukning; Flygdata; Flygplanens prestandamodell; Flygplans förbrukningsmodellering; Viktad medelvärdesensemble; Maskininlärning;

    Abstract : Performance models provided by aircraft manufacturers are used by aircraft operators to perform flight path simulations aiming to reduce aircraft fuel consumption. However, performance models are generic and does not account for the performance deviations of each aircraft individual. READ MORE

  4. 3. Obtaining Pitch Control for Unmanned Aerial Vehicle Through System Identification

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

    Author : Lucia Karens; Tawsiful Islam; [2022]
    Keywords : pitch control; flight tests; unmanned aerial vehicles UAV ; system identification; PID control;

    Abstract : This study aimed to develop and evaluate a method to obtain a proportional-integral-derivative (PID) controller. The controller is for a control surface that controls pitch motion, by using data from flight tests with an unmanned aerial vehicle (UAV). READ MORE

  5. 4. First Principle Parameter-Based Performance Model for Commercial Turbofan Aircraft

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

    Author : Jacob Wrase; [2022]
    Keywords : ;

    Abstract : Climate change and greenhouse gas emissions are arguably some of the most pressing threats that today's society has to face. Emissions from the transport sector, including air traffic, play an important role in the pursuit of reducing climate impact. READ MORE

  6. 5. Terrain Referenced Navigation with Path Optimization : Optimizing Navigation Accuracy by Path Planning

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

    Author : Martin Gelin; [2022]
    Keywords : Terrain Referenced Navigation; Localization; Particle Filter; Rao-Blackwellized Particle Filter; Kalman Filter; Path Planning; Terrängbaserad navigering; Lokalisering; Partikelfilter; Rao-Blackwelliserat partikelfilter; Kalmanfilter; Banplanering;

    Abstract : Terrain referenced navigation is a method of navigation that uses measurements of altitude above ground to infer the position of the vehicle, mainly aerial or underwater. This method provides an alternative to the commonly used satellite-based navigation. READ MORE
