报告摘要:

    The report shows the development of high-altitude aerial vehicle in recent years, e.g., airships, showing the necessity of the application of thrust-vectored technology. A general physical model of the mechanical thrust-vectored system is established with consideration of the real structure characteristics by means of Hamilton's principle. Three fundamental physical models, including natural vibration model, beam-rotor aeroelastic model and wing-rotor aeroelastic model, are introduced for the purpose of modal and aeroelastic analyses. Also the solving technique is presented to show the improvement of computational accuracy. The analyses are focused on the stability performance of the whole system, where the influence of structural and external factors are evaluated through parametric studies. Further, the rotor-to-wing interference is also measured through frequency-domain modeling.
