This paper describes identification and components of destructiveness of energy, economic and ecologic profits and outlays during life cycle of offshore wind electric power plants as well as the most useful models for their design, assembly and use. There are characterized technical conditions ( concepts, structures, processes) indispensable for increasing profits and/or decreasing energy, economic and ecological outlays on their operation as well as development prospects for global, European and domestic markets of offshore wind electric power industry. A preliminary analysis was performed for an impact of operators, processed objects, living and artificial environmental objects of a 2MW wind electric power plant on possible increase of profits and decrease of outlays as a result of compensation of destructiveness of the system, environment and man.

It is widely known that during the post-harvest handling of a number of crops pneumatic separators are often used. It is proved that in order to improve separation process by using an air flow becomes possible through the use in the separation channels an electric field of corona discharge as additional working body. The electric field makes an additional force effect on the particles of the separated mixture. Since the seeds of cultivated plants and weeds belong to different species, their electrical properties interact with the working bodies of pneumatic separators in different ways that enables quality improvement of seed mixtures separation. We consider the ellipsoidal particles’ behaviour under the influence of gravity, electric power and air flow in pneumo-electric separator channel taking into account their bumping into the walls. We also worked out the differential equations that reflect the mathematical model of the particles under the totality of these forces. This model describes the movement of particles in the pneumo-electric separator channel and allows at any time to calculate the coordinates of trajectories. Based on their analysis we can explore the influence of the controlled process parameters on the pneumo-electric separation and determine their optimal parameters under which the separation of the investigated seed mixtures is the most effective and the components of which are of ellipsoid shape.

It is offered the automated complex for carrying out experimental researches automobiles and tractors engines with program realization of monitoring of a kind speed-mode on coefficient to non-uniformity of a course. In the developed installation it is automated processes definition, on dynamic modes, the expenditure of air and fuel and coefficient surplus of air and provided an opportunity of a direct estimation of quality of a transitive mode of engines.

The behavior of seed in pneumo-electric separator channel is revealed. The characteristic of the active forces on ellipsoid-shape seed is demonstrated. Due to a differential equations you can find the coordinates of seed mixtures particles’ motion to determine the conditions under which we get maximum effect.
