11. Aerodynamic Optimization of Low Observable Engine Intake Duct
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : An aerodynamic shape optimization procedure was performed on a low observable engineintake duct. The intake duct was fixed in its throat and aerodynamic interface plane (AIP)sections, while leaving up to 7 design parameters free to deformation in the centroid curveand mid section profile.

12. Electrical Propulsion System Design of a Blended Wing Body UAV
University essay from KTH/Skolan för teknikvetenskap (SCI)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.

14. Three-way catalyst calibration and system modelling for CNG engine exhaust aftertreatment
University essay from KTH/KemiteknikAbstract : Detta projekt behandlar metodutveckling för att modellera en trevägskatalysator som skulle kunna användas vidare för att uppskatta utsläppen från en Ottomotor. Modellen är byggd i AVL Cruise M för att bestämma omvandlingarna för de tre lagstiftade föroreningarna kolmonoxid, kväveoxider (NOx) och metan baserat på reaktioner som sker i trevägskatalysatorer.

15. Adhesive bonding of fiber laminate patch to sandwich-structured composite
University essay from Lunds universitet/MaterialteknikAbstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE
