  2. 1. On aircraft fuel system design : concept evaluation and system modeling

    Author : Hampus Gavel; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : THE LARGEST AND most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. READ MORE

  4. 2. Active Noise Control in Aircraft : Algorithms and Applications

    Author : Sven Johansson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise control; feedforward control; filtere-x lms algorithm; complex lms; multichannel system; multiple reference; aircraft; headset;

    Abstract : The thesis consists of five papers which are divided into three main parts. Parts A and B deal with active noise control in a propeller aircraft application, whereas Part C deals with active noise control in a helicopter application. READ MORE

  6. 4. Knowledge Based Integrated Multidisciplinary Aircraft Conceptual Design

    Author : Venkata Raghu Chaitanya Munjulury; Petter Krus; Roland Stolt; Linköpings universitet; []
    Keywords : Knowledge-base; Aircraft; Conceptual Design; CAD; XML Database; Multidisciplinary; Optimization;

    Abstract : With the ever growing complexity of aircrafts, new tools and eventually methods to use these tools are needed in aircraft conceptual design. To reduce the development cost, an enhancement in the conceptual design is needed.This thesis presents a knowledge-based aircraft geometry design tool RAPID and the methodology applied in realizing the design.

  7. 5. On Standardized Model Integration : Automated Validation in Aircraft System Simulation

    Author : Robert Hällqvist; Petter Krus; Magnus Eek; Robert Braun; Henrik Tidefelt; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Designing modern aircraft is not an easy task. Today, it is not enough to optimize aircraft sub-systems at a sub-system level. Instead, a holistic approach is taken whereby the constituent sub-systems need to be designed for the best joint performance. READ MORE
