  1. 1. Development & Integration of Load Path Visualization With the U* Index Method : Applications In Aerospace Product Development

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Oscar Johansson; Jonathan Muistama; [2022]
    Keywords : U* index; Inspection load; ModSim; TRL; U* index; Inspektionslast; ModSim; TRL;

    Abstract : Determining how loads are distributed in a structure has long been a way for engineers to ensure that the final product will work as intended. As components become more and more complicated so does this analysis. The advantages of quickly identifying critical features in a design are significant. READ MORE

  2. 2. Quotation for Customer Proposal and Performance Analysis for aircraft maintenance

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

    Author : Antoine Bezier; [2022]
    Keywords : Maintenance; aircraft; quotation; performance analysis; internship; aerospace engineering; databases; feedback; customer support; request for proposal; repair; technical work preparation.; Flygplansunderhåll; prestandaanalys; flygteknik; databaser; kommersiellt erbjudande; kontinuerlig förbättring.;

    Abstract : By working as an intern with the Quotation Officer of Sabena Technics Nîmes facility,an aircraft maintenance company, this degree project highlights the different factors totake into account in a quotation of civil planes (B737/B767/A320/A330) by analysingwork packages from airline company, applying a process to estimate the importantdata as the man hours or tools, and using my technical knowledge to understandmaintenance tasks. Management knowledge for commercial sale reviews was usefulas well, this job is in the middle of the commercial team and and the technicalteam. READ MORE

    Abstract : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

  4. 4. Modeling and simulation of chromatographic separation in Modelon Impact

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Oliver Thelander; [2022]
    Keywords : Chemical engineering; Simulering; Modellering; Kromatografi; Adsorption; Modelica; Modelon Impact; Recirkulation; Simulation; Modeling; Chromatography; Recirculation; Technology and Engineering;

    Abstract : The aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. READ MORE

  5. 5. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    University essay from Umeå universitet/Institutionen för fysik

    Author : Medet Kiflemariam; [2021]
    Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.
