  1. 1. Conceptual Design and Analysis of an Unmanned Autonomous Expendable Air Vehicle

    University essay from KTH/Flygdynamik

    Author : Alicia Huzelius; Hanna Kindberg; [2018]
    Keywords : ;

    Abstract : This project have looked into the possibility to develop a small autonomous expendable air vehicle to be used with other air vehicles to fly in a group or a swarm. The requirements of this project was that the air vehicle should be able to carry a payload of 8 kg, have arange of 100 km and fly at an subsonic speed at an altitude between 0 to 3000 meter.

  3. 2. Estimation of Engine Gas Temperatures During Pressure Transients

    University essay from Linköpings universitet/Fordonssystem

    Author : Marcus Wallson; [2018]
    Keywords : ;

    Abstract : Coming stringent regulatory emissions requirements with Real Driving Emissions testing amplifies the need for efficient engine control at all driving scenarios. This thesis has investigated the air-flow transients that appears when changing the throttle position very fast, such as at a stop sign. READ MORE

  4. 3. Estimation of Air Mass Flow in Engines with Variable Valve Timing

    University essay from Linköpings universitet/Reglerteknik

    Author : Elina Fantenberg; [2018]
    Keywords : Diesel Engine; Variable Valve Timing; Air Mass Flow;

    Abstract : To control the combustion in an engine, an accurate estimation of the air mass flow is required. Due to strict emission legislation and high demands on fuel consumption from customers, a technology called variable valve timing is investigated. READ MORE
