New Principles for Dynamic Aircraft Exergy Mapping

Autor: Martin J. Balchin, Frederick Berg, Patrick Keogh

Publikováno v: Journal of Aircraft. 50:1088-1098

As fuel efficiency becomes a greater concern in commercial aircraft design and operation it is important to gain a deeper understanding of energy use throughout an aircraft’s systems. To meet this need, a new methodology is being developed that pro

Analysis of heteropolar inductor machines based on space vectors

Autor: Martin J. Balchin, Jingzhe Wu

Publikováno v: 2013 3rd International Conference on Electric Power and Energy Conversion Systems.

The concept of heteropolar inductor machines is introduced, including the history, general geometry and electrical properties. Modifications are made to conventional topology for improved effectiveness. The armature space vectors and field dynamic eq

Elucidation of Aircraft Energy Use Through Time-Variant Exergy Analysis

Autor: Patrick Keogh, Martin J. Balchin, Frederick Berg

Publikováno v: SAE Technical Paper Series.

Increases in fuel costs and environmental concerns have in recent years heightened the importance of fuel efficiency as a design consideration in vehicles, especially aircraft. For this reason, a greater understanding of the energy consumption of veh

Effects of pole flux distribution in a homopolar linear synchronous machine

Autor: J. F. Eastham, M. J. Balchin, P.C. Coles

Publikováno v: Journal of Applied Physics. 75:6987-6989

Linear forms of synchronous electrical machine are at present being considered as the propulsion means in high‐speed, magnetically levitated (Maglev) ground transportation systems. A homopolar form of machine is considered in which the primary memb
