Introduction: Design practicalities
A project viewed favourably by relevant parties after a first-pass feasibility study can progress to the subsequent stage. This will require the design details to be fleshed out and a more in-depth knowledge of turbine technology. Therefore, this section serves to inform project leaders and designers on key technological issues and practical aspects. This includes elaboration of a number of terms alluded to during the preceding sections (such as drag and lift forces, coefficients of performance, tip speed ratio and overspeed control) through the illustration of the fundamental principles behind these key topics. Concise descriptions are provided to allow timely progression, avoiding the less easily digestible ‘higher level’ of knowledge required by manufacturers and equipment designers.
