| Abstract: | An optimum method for the shape parameters of the wing and the wingtip is studied.The optimization model of the wing and the wingtip is constructed by radial base function(RBF).The optimization object is to obtain minimum of the induced drag for the wing with/without the bending moment constrain at the wing root,combined with sequence quadratic programming or quasi Newton methods,respectively.Results show that optimization effect is satisfied.The research for optimum design problem of the wingtip can provid... |
