Restricted by the condition and equipment of the experimentation, validly testing all kinds of aero-condition of the sandwich-curve-cone nose with the traditional experimentation method is difficulty and likely endangers the sample. By adjusting and optimizing the magnitude and subsection of the testing load with the method of engineering and FEA, the overall and valid static-experimentation of the sandwich-structure with the Von-Carmen cone is realized. This method is validated by the comparing test.
