  • Abstract: An unusual form of polyphase armature winding is described in which conductors lie on a helix of constant radius as they pass from one end of the machine to the other. There are no end windings. An analysis of the winding is peformed which allows analytic expressions for the flux densities and machine reactances to be found. Measured and calculated values of synchronous reactance agree to within 2%. Some of the more unusual properties of helical windings are discussed.  Further notes on helical windings 
 

Rotating power source
                      for on-board telemetry: On-board power source for Rotating Telemetry
overcame the need for on-board battery supplies for turbine rotor telemetry.
UK patent. Product licensed to Technitron UK
 


Multi-level, structured Breakdown of Power Plant on a systematic and generic basis into
  • Main Product Groups (Main Turbine System, Electrical Generation System etc)
  • Functional Product Elements (HP Turbine, IP Turbine.... Generator, Exciter etc)
  • Sub-systems, sub-assemblies etc
Used as basis for identification of the extent of supply, and as the common identifier for all information associated with the plant.      Further notes.
Development of Product Structure based identification system for Turbine Generator  Plant
managed the team responsible for designing and implementing a structured coding system for product identification and cost estimating for use throughout the design and manufacturing cycle. System successfully implemented within NEI Parsons in the mid 1980s as basis of  the Power Plant Project Management System
 


Application of object-oriented principles to Turbine-Generator Plant design & manufacture
managed the team responsible for introducing the object-oriented approach in engineering computing applications and for organising trials of intelligent CAD systems within NEI Parsons in the late 1980s.Early development of a product configurator by a member of the team was later taken up by a major software company.
