  1. 21. Does the use of ambulance helicopter shorten the transport time for trauma patients in Arvika Hospitals catchment area in comparison with land-based ambulance transport?

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Raimo Lindgren; [2018]
    Keywords : ;

    Abstract : Introduction: The ambulance helicopter has been an established part of the trauma care in Värmland since 2014. European studies comparing the ambulance helicopters with land-based ambulance often show reduced mortality among patients handled by helicopter. A factor often considered as a risk reducer is shortened transport time. READ MORE

  3. 22. Autonomous Hover Control System for a Radio-Controlled Aerobatic Airplane

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Erik Olov Ljudén; [2018]
    Keywords : mechatronics; hovering; airplane; PWM; aerobatics; mekatronik; hovring; flygplan; PWM; konstflygning;

    Abstract : Being able to fly has always been one of humanities greatestdreams, and today anyone can purchase a Radio-Controlled(RC) airplane or helicopter and learn how to fly. ExperiencedRC pilots perform stunts such as “prop hanging”.This is when an airplane flies vertically while maintainingits position with the propeller being the only motive force. READ MORE

  4. 23. Modelling and Identification of a RUAV

    University essay from Linköpings universitet/Reglerteknik

    Author : Alaa Saeed; Mattias Mucherie; [2018]
    Keywords : ;

    Abstract : Modelling a linear mathematical model of a radio controlled (RC) helicopter in hover is the main goal of this thesis. The thesis introduces a general description about how RC-helicopters work and different phenomenons that effect the behaviour of a RC-helicopter. These phenomenons play an important role in the modelling part. READ MORE
