Определение демпфирующих сил, возникающих при вертикальных колебаниях судна на воздушной подушке на крейсерском режиме движения
Вестник Волжской государственной академии водного транспорта. 2018. № 55. С. 73–82.
The present paper deals with damping pressures associated with vertical motions of air cushion vehicles. A damping pressure is defined as a difference between an actual air cushion pressure of a vehicle in a vertical motion and a pressure inside a vehicle’s air cushion calculated by a simple mass balance law. The paper presents the problem statement and the simulation results. It is demonstrated that taking into account this kind of forces leads to significant decrease in heave and pitch as well as vertical accelerations in head sea conditions.

Uniaxial tensile testing of flat specimens under superplastic conditions is widely used to determine the deformation behavior of materials. However, the standard interpretation of the results relies on the hypothesis of an ideal uniaxial stress state and often fails to account for the influence of specimen geometry and material flow from the gripping zones to ...

We present analytical and numerical investigations of the size and shape evolution of localized disturbances during their propagation in elastic media (furthermore, we refer to this process as energy dispersion). We consider two models of media: the continuum, described by the multidimensional wave equation, and the simple scalar harmonic lattice. The presented research is based ...

This study presents an extended dissipative analysis of fractional order fuzzy networked control system with uncertain parameters. First, we designed the network-based fuzzy controller for the considered model. Second, a novel Lyapunov-Krasovskii functional (LKF) approach, inequality techniques, and some sufficient conditions are established, which make the proposed system quadratically stable under the extended dissipative criteria. ...

We propose the method for calculating the probability of a safe landing for ship-based aircraft. We define a safe landing as the event that the initial touch of the landing surface by an aircraft occurs on a given segment of the deck, and at the time of this contact, the phase coordinates of the aircraft ...

This paper considers aircraft landing on a carrier. We propose two schemes for calculating, first, the probability of a go-around due to disengaging the arresting gear and, second, the maximum descent of the aircraft’s trajectory with respect to the deck level immediately after leaving the deck. The instant to increase the aircraft’s thrust before touching ...

The behavior of any real system is a process to a greater or lesser degree probabilistic. As a rule, it is impossible to specify exactly which external influences and internal mechanisms of interaction of the system components will be decisive in the future. As a consequence, we cannot accurately predict the behavior of the system. ...
