1. 1. Improving Aircraft Fuel Consumption Prediction through Ensemble Learning

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Hanlin Gongzhang; [2022]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Aircraft Winglet Design

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Hanlin GongZhang; Eric Axtelius; [2020]
   Nyckelord :;

   Sammanfattning : Aerodynamic drag can be decreased with respect to a wing’s geometry, and wingtip devices, so called winglets, play a vital role in wing design. The focus has been laid on studying the lift and drag forces generated by merging various winglet designs with a constrained aircraft wing. LÄS MER
