GadShannan DESIGN Akademin för Innovation, Design och Teknik Designing a Very Light Jet Master thesis work 30 credits, D-level Product and process development, concurrent engineering Master Thesis Programme Innovation and Product Design Per Nyblom Report code: IDPPOPEXD:08:11 Commissioned by: GadShaanan DESIGN Tutor (company): Mladen Barbaric Tutor (university): Ragnar Tengstrand Examiner: Rolf Lövgren Abstract Introduction Very light jet is a hot subject growing stronger and stronger. The new type of air craft is an air plane that weighs less than 10000 pounds and uses a jet engine. Problem The student was proposed to designing a conceptual very light jet that could be used for inspiration and accepted the challenge. Method In this thesis the reader can follow the project progress in detail, the proposed methods and the results. The student divided the project into four activities analysis, creation, development and documentation. Result The project ended with a concept very light jet with simple specifications. Illustrations for inspirational usage and a simulation testing for verification of the proposed concept specifications.
