    Författare :Adrien Bérard; Arthur Rizzi; Dieter Scholz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft conceptual design; Computer Aided Design CAD ; buffet onset; unsteady vortex-lattice method; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis presents the work done to implement new computational tools and methods dedicated to aircraft conceptual design sizing and optimization. These tools have been exercised on different aircraft concepts in order to validate them and assess their relevance and applicability to practical cases. LÄS MER

  3. 2. On aircraft fuel systems : conceptual design and modeling

    Författare :Hampus Gavel; Petter Krus; Johan Ölvander (Andersson); Dieter Scholz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft; morphological matrix; simulation; Saab; Gripen; Construction engineering; Konstruktionsteknik;

    Sammanfattning : 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. LÄS MER
