      Avenant, Gerrit Christiaan (Stellenbosch : University of Stellenbosch, 2010-03)
      ENGLISH ABSTRACT: In recent years, the use of airships has become popular for observation purposes since they provide a cost effective alternative to other aircraft. For this project a lateral and longitudinal flight ...

    • Autonomous flight of a model aircraft 

      Peddle, Iain K. (Stellenbosch : Stellenbosch University, 2005-03)
      The successful development of a conventional flight autopilot for a model aircraft is presented. All aspects of the autopilot design are considered, from modeling to flight tests. A mathematical aircraft model, as a ...

    • Autonomous flight of an unmanned helicopter 

      Rossouw, Louis-Emile (Stellenbosch : Stellenbosch University, 2008-03)
      ENGLISH ABSTRACT: The successful development of an autopilot for an unmanned helicopter is presented. The helicopter model is developed from first principles. The model is decoupled to enable the design of four separate ...

    • Autonomous landing of a fixed-wing unmanned aerial vehicle onto a moving platform 

      Le Roux, Cornelus Tjaart (Stellenbosch : Stellenbosch University, 2016-12)
      ENGLISH ABSTRACT: This thesis presents the analysis, design, simulation, implementation and partial practical flight testing of a flight control system to achieve accurate autonomous landing of a fixed-wing unmanned aerial ...

    • Autonomous landing of a fixed-wing unmanned aerial vehicle using differential GPS 

      Smit, Samuel Jacobus Adriaan (Stellenbosch : Stellenbosch University, 2013-03)
      ENGLISH ABSTRACT: This dissertation presents the design and practical demonstration of a flight control system (FCS) that is capable of autonomously landing a fixed-wing, unmanned aerial vehicle (UAV) on a stationary ...

    • Autonomous landing of a fixed-Wing unmanned aircraft with partialwing and stabiliser losses 

      Hugo, Gideon (Stellenbosch : Stellenbosch University, 2017-03)
