  1. 11. Development and Use of System Modeler 6DOF Flight Mechanics Model in Aircraft Conceptual Design

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Niko Erä-Esko; [2022]
    Keywords : Aircraft Conceptual Design; Flight Mechanics; Modelling and Simulation;

    Abstract : This thesis presents a tool for conceptual design of a traditional configuration aircraft by using a parametric six degrees of freedom (6DOF) flight mechanics model implemented in the Modelica Language using Wolfram System Modeler. Being first only able to model and simulate the uncontrolled flight of an aircraft with fixed mass and centre of gravity (CG), and requiring detailed aerodynamic parameters as an input, the 6DOF model is improved by developing new features to reduce the number of required inputs while also increasing the data output of the simulations.

  3. 12. Dynamic Synthesis of Pilot Actions for Multiple Faults during Flight

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Louise Nilsson; Malin Rahm; [2022]
    Keywords : ;

    Abstract : In today’s JAS 39 Gripen E there is a central system that collects all failures that occur in the aircraft. Complex failures often generate multiple simultaneous alerts. This makes it difficult for the pilot to get an overview of the active alerts. Each alert has a number of actions that the pilot must handle. READ MORE

  4. 13. Automatic Creation of an Aircraft Structural Layout and Structural Analysis Model : A method for implementing design automation in an early conceptual design phase

    University essay from Linköpings universitet/Produktrealisering

    Author : Philip Brånäs; Nora Enderby; [2022]
    Keywords : Design automation; Structural layout; Structural analysis model; Conceptual design; Conceptual aircraft design; fuselage;

    Abstract : Aircraft structural layout concept design at Saab Aeronautics utilize thickness optimizationto evaluate astructural layout concept. The thickness values can be used to compare conceptsto each other,and the bestonecan be further developed. Today, most ofthe creation and evaluation of structural layout concepts is manual work.

  5. 14. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sergi Tarroc Gil; [2021]
    Keywords : Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

    Abstract : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. READ MORE

  6. 15. Development of a Tool for Inverse Aerodynamic Design and Optimisation of Turbomachinery Aerofoils

    University essay from KTH/Flygdynamik

    Author : Berkin Kurtulus; [2021]
    Keywords : Aerodynamics; Turbomachinery Airfoil design; Inverse Design Automation; Airfoil Optimization;

    Abstract : The automation of airfoil design process is an ongoing effort within the field of turbo-machinery design, with significant focus on developing new reliable and consistent methods that can meet the needs of the engineers. A wide variety of approaches has been in use for inverse airfoil design process which benefit from theoretical inverse design, statistical methods, empirical discoveries and many other ways to solve the design problem.
