摘要：The integrated design and manufacture of aircraft aerodynamic elasticity
   wind tunnel test model and supporting mechanism,the aerodynamic
   responses and precise perception of complex experimental environment of
   wind tunnel test model,and supporting mechanism and the high quality
   precision control of wind tunnel test model and supporting mechanism are
   key common technologies of large low temperature high Reynolds number
   wind tunnel,large continuous transonic wind tunnel,large low-speed wind
   tunnel, high temperature hypersonic wind tunnel.These key technologies
   are extremely important to take full advantage of wind tunnel action and
   serve the development of future new aircraft effectively.There are some
   key common technologies that need to be solved urgently in future
   large-scale wind tunnel test, including the integrated design and
   manufacture of the material,structure and function involved complex
   products,nonlinear dynamics of complex rigid-flexible hybrid,the
   perception and analysis of high dynamic multidimensional physical
   information,and coupling control of aerodynamics and flight mechanics.In
   the construction of large wind tunnels,the only shortcut to make the
   large wind tunnel play its proper scientific and engineering role is to
   solve a number of common key technologies needed in large wind tunnel
   test.The solutions to these key technologies depend on basic science
   questions about manufacturing,perception and control of model/support in
   aeroelastic effect test.
