Argues that the costs and problems of quality are largely predetermined in product development and, therefore, there are limits to what can be achieved thereafter by the application of best‐practice manufacture and quality control. Presents knowledge‐based design‐for‐quality methods...

This paper is concerned with the design, development and performance testing of a permanent magnet (PM) generator for wind turbine applications in urban areas. The radially interacting armature windings and magnet array are carried on direct drive, contra-rotating rotors, resulting in a high...

Turbine types suit specific ranges of head, flow rate and shaft speed and are usually categorised by specific speed. In the pico range, under 5 kW, the requirements are often different to that of larger scale turbines and qualitative requirements become more influential in selection. Pico hydro...

Turgo turbines are reported to be reliable, robust and able to operate efficiently over a range of flow rates. They are typically used in medium- to high-head applications. In this paper, the operation of a single-jet Turgo turbine outside of this typical application domain is investigated, at...
