Abstract

In this paper, it is proposed, very briefly, to review the traditional methods of manufacture of steam-turbine blades, to comment on the different technical requirements of blades for gas turbines and then survey the history of some of the developments in manufacturing methods of blades for gas turbines with particular reference to the methods developed for the production of blades for an early series of axial-flow jet engines.

As by far the larger proportion of blades in an axial-flow aero-engine are compressor blades, this paper is largely concerned with the development of compressor blade manufacturing methods. The paper concludes with a short appreciation of the past and future competitive positions of the precision forged and machined stainless-steel compressor blade.
