AUTOMATED APPROACH FOR DESIGN OF TRANSPORT AND TECHNOLOGICAL VEHICLES WITH ROTOR AND SCREW MOVERS

 

Nizhny Novgorod State Technical University n.a. R.E. Alekseev

 

The paper presents the results of theoretical studies of the motion of the rotary-screw machines over the broken ice. A preliminary mathematical model of resistance developed and allows approach to the calculating of expenditure of power for overcoming the resistance of the body in fine ice and ice floes with relatively large size. A description of the interaction of the rotary-screw mover with water-ice environment that allows forecast the impact of the real factors on traction and energy parameters of rotary screw machines in condition of movement over broken ice. The paper presents dependencies, allowing determine the rational design parameters of transport and technological rotary screw machines. Generalized mathematical model of interaction of rotary screw machines and their movers with broken ice on the basis of the experimentally obtained constants opens the way to create a single automated approach for designing of complex rotary-screw transportation and technological vehicles.

 

Key words: design parameters, rotary screw machines, rotary screw movers, driving resistance, the diameter of the base of the cylinder, the height and the angle of winding of the blade.

THE FUTURE OF DYNAMICALLY SUPPORTED SHIPS

 

There are significant differences between the dynamically supported ships and the displacement-type ships along with other water transport. The lift over drag ratio, service-speed ranges and transport efficiency mark of various ships in terms of guidance paper are introduced as test parameters. It becomes evident that the dynamically supported ships allow to realize a high-speed shipping successfully and to redefine it for a viable solution of multiple strategic and defense tasks in the XXI century.

 

Key words: dynamically supported ships, speed ships, development prospects.

Nizhny Novgorod State Technical University n .a. R.E. Alekseev

 

The paper reveals with the problem above and the practical application of the hydrodynamic method of copying. The development of new hydrofoil’s on the basis of hydrodynamic schemes such vessels, which have been developed and tested by doctor of technical Sciences, Laureate of State and Lenin prizes of R. E. Alekseev and his school in the field of high-speed shipbuilding is a time-efficient and cost trends in Russia. We are talking about modeling in the format of a dynamic theory of hydrodynamics similarity of the two systems. Published the statistical graph that establishes the passenger capacity and mass with a displacement. It is the development of authors. This statistical graph allows you to select the most suitable real hydrofoil, which serves as the base models designed object. His scheme hydrodynamic layout will be the basic model for a similar complex designed object.
