  1. 1. Spacecraft dynamic analysis and correlation with test results : Shock environment analysis of LISA Pathfinder at VESTA test bed

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Beata Iwona Kunicka; [2017]
    Keywords : FEA FEM; finite element analysis; finite element method; mechanical analysis; structural analysis; dynamic analysis; computational dynamic analysis of structures; shock analysis; shock environment; shock test; shock test campaign; spacecraft dynamic analysis; MSC Nastran; MSC Patran; Dynaworks; Shock Response Spectrum; SRS; space engineering; space science and technology; mechanical engineering; structural engineering; analysis optimisation; analysis parametrisation; mechanical wave propagation; shock propagation; damping; hysteretic damping; viscous damping; structural damping;

    Abstract : The particular study case in this thesis is the shock test performed on the LISA Pathfinder satellite conducted in a laboratory environment on a dedicated test bed: Vega Shock Test Apparatus (VESTA). This test is considered fully representative to study shock levels produced by fairing jettisoning event at Vega Launcher Vehicle, which induces high shock loads towards the satellite. READ MORE

  3. 2. Investigation of sandwich shells modelling in order to simulate with robustness the mechanical behaviour of the launchers upper part structures

    University essay from KTH/Lättkonstruktioner

    Author : Paul Cochelin; [2017]
    Keywords : ;

    Abstract : This paper presents the development of a finite-element model used to study the separation of a launcher payload fairing. This work has been carried out at the French National Space Agency (CNES). READ MORE

  4. 3. Simulation of the behavior of a payload fairing during separation

  5. 4. Automated generic parameterized design of aircraft fairing and windshield

    University essay from Fluida och mekatroniska system

    Author : Aakash Narender Singh; Vijay Govindharajan; [2012]
    Keywords : Catia V5; Aircraft; Fairing; Windshield; Parametric; Generic; design; Catia V5; Aircraft; kåpen; frontrute; Parametric; Generic; design; Catia V5; flygplan; Kåpa; vindruta; Parametric; Generic; design;

    Abstract : The process of design is time consuming and result oriented. There is always a better scope for any design that reduces the time with better precision. Considering this as a major factor during design process, two of the vital parts of the aircraft conceptual design are taken into account where a lot of time can be saved. READ MORE

  6. 5. Motorcycle Cornering Improvement : An Aerodynamical Approach based on Flow Interference

    University essay from KTH/Aerodynamik; KTH/Mekanik

    Author : Vojtech Sedlak; [2012]
    Keywords : aerodynamic; fluid mechanics; interference; blockage; airfoil; wing; bluff body; motorcycle; moto; motorbike; MotoGP; road racing; aerodynamik; fluid mekanik; flöde interferenser; vinge; motorcyckel; MotoGP; roadracing;

    Abstract : A new aerodynamic device, based on flow interference effects, is studied in order to significantly improve the cornering performance of racing motorcycles in MotoGP. After a brief overview on why standard downforce devices cannot be used on motorcycles, the new idea is introduced and a simplified mechanic analysis is provided to prove its effectiveness. READ MORE
