Abstract:
Based on the common disturbed mot ion equation of project iles, Liapunov funct ion V( X ) = X* HeX in plural number mode is const ituted w ith the help of Hermite matrix He and Liapunov. s direct method. From the posit ive definiteness conditions of the matrix He , it has derived dy namical stability condit ions of project iles in f light. This also provides a new w ay to study flight stability.
