      The paper describes an approach to using algorithms for calculations in applied aerogasdynamics on multiprocessors. The parallelization of algorithms is exemplified by calculating the supersonic flow over a real aircraft.

      A method is presented for dividing the dynamic force characteristic of a coupling element in a one-degree nonlinear mechanical system into rigid and damping components. The coupling parameters were identified using the invariant immersion technique allowing to estimate simultaneously both state vectors and system parameters.
      The method capabilities are exemplified by defining force characteristics of two elements, one of them representing a sufficiently complex system where the paste flowing through the adjustment hole was used to create the stress.
      Theoretical oscillograms for element overloading and deformation agree well with experimental ones obtained from shock loading.
