    Abstract
  • A novel approach was outlined to generate flight load spectrum for a new civil airplane from the statistical data of actural flight load on similar type of ones. The flight spectrum and continuous stress sequences of new civil airplane were derived from the statistical data of actural flight load of B737-400 plane by means of the analogism and the gust and maneuver spectra were then generated on the basis of the TWIST method. Finally, 5 5 ground-air-ground spectrum was obtained from the random sequencing. The example shows the practical application of new approach.
