STRUCTURAL ARCHITECTURE OF PRORA-USV TRANSONIC FLIGHT TEST VEHICLE

摘要

This paper presents the structural architecture of the PRORA-USV first experimental air vehicle (named FTB_1, Flight Test Bed 1) developed for transonic regime missions and shows how this architecture has been driven by programmatic aspects and by some peculiar technical requirements. Carlo Gavazzi Space (CGS) is developing the Structure Subsystem for the FTB_1 vehicle under contract of CIRA. At the time of the Conference (may 2005), the integration of the first structure on the assembly jig is in progress.The architectural concept has been driven by programmatic constraints and requirements generated by the experimental nature of the test vehicle:■ reduce development (design and Manufacturing Assembly integration and Testing - MAIT) time,■ risk reduction approach,■ concept robustness to requirement modifications and uncertainties.The paper will presents how the structural architecture is able to meet the above mentioned constraints and requirements. The Structure includes also the mechanical control chains of ailerons and rudders, with stringent requirements.
