Page:Model steam turbines; how to design and build them (IA modelsteamturbin00harrrich).pdf/8



steam turbine has rapidly come to the front during the last few years on account of its many advantages as compared with its older rival, the reciprocating steam engine.

From a model point of view also, several advantages may be claimed for it; thus for model steamer work its light weight and the fact that the centre of gravity is low, are two conditions which make it specially applicable for high-speed craft.

In this small book it is proposed to lay down the principles on which model steam turbines may be designed and some examples, either built or projected, are given, being for the most part taken from the columns of The Model Engineer.

need for a third edition of this book having arisen, advantage has been taken of the opportunity to partially re-write it and to add further matter.

The reader is earnestly recommended to thoroughly master Chapters I. and II., as he will then have a very fair knowledge of the theory underlying the design and construction of steam engines in general.
