| Summary: | A technique for assessing the transport energy efficiency on the basis of the life cycle is developed with the use of the Bartini Transfer entity.
Main elements of the technique are the following: 1) assertion of the necessity to correlate (compare) the amount of energy to the absolutized transfer of a transport object with the life-cycle Cumulative Energy Demand (CED); 2) selection of the Bartini Transfer entity (and the corresponding cell of the Bartini table) for the mentioned correlation; 3) use of the Tiguntsev model for calculations of the kinetic and potential energy for the motion of an absolutized transport object in the gravitational field; 4) construction of a diagram with axes Speed V and Specific CED; 5) carrying out of the analysis in the field of the V–CED diagram for the comparison of the amount of energy to the transfer of an absolutized transport object with the transport system CED for such transportation. A number of examples are given. |
