AS the basis of this examination I have taken the results obtained by H. Roxbee Cox in his “Statistical Method of Investigating Relations between Elastic Stiffnesses of Aeroplane‐Wings and Wing‐Aileron Flutter”, which may be briefly recalled.

Abstract
The first gas turbine patent was granted in England to John Barber in 1791, and since then there have been numerous gas turbine inventions. These have been adequately described elsewhere, 1, 2 and I shall concern myself only with the developments which have led directly to recent British achievements.

THIS paper seeks to draw from current research work on flutter and related problems results of general design significance ; and, avoiding mathematics, endeavours to set these results out in relation to past and present problems.

Abstract
A STUDY of the economic design and operation of the rigid airship must take account of many variables; power, speed, range, useful load, volume and structure weight—to cite the most obvious—have presumably absolute values which, in combination for a particular duty, produce the most economical whole. With the very limited knowledge of design and operation which we have at present, it is not possible to attempt a comprehensive enquiry, but certain of the simpler aspects of the problem of the economics of the rigid airship can be considered with advantage. The present note is an attempt to discuss, very elementarily, and on what are thought to be reasonable assumptions, the variation of structure weight with gross volume.

Abstract
Based on a lecture prepared as part of the celebration of Cranfield University's 50th anniversary. After briefly reviewing the early years, including Cranfield University's entry into this technology, discusses the nature of this industry, Some of the technology drivers, including environmental concerns, are examined to provide a background against which the development and the future of the industry can be considered. This is followed by a brief survey of some of the possible new civil aero gas turbine applications over the next 50 years, both the very likely and some curiosities. Finally, the changes that are likely to occur within the industry as a result of wider economic and political trends are considered, as well as the implications for those working within the industry. The development of the civil aero gas turbine has contributed, in large measure, to today's, US$ 300 billion civil aviation industry and is rightly seen as one of mankind's major engineering achievements. A single paper cannot do justice to this industry.

Abstract
IN these notes, the stillness of thin shells is discussed from three different viewpoints. Throughout, the basis of the argument is the elementary Batho‐Bredt torsion formula and no attempt is made to discuss the effects of end or other constraints on the straight‐forward conclusions obtained on this simple basis.

Abstract
IT appears from published work on brakes that no general theoretical basis has been presented on which the problem of the servo shoe brake can be studied, though empirical procedures have been used and special cases have been examined analytically. In this essay a simple theory is presented for dealing with brakes having any number of shoes; in it the pressure distribution on any shoe is a function of the conditions of equilibrium, of the system and of simple assumptions which it is thought will be generally acceptable. By means of this theory, the effects of variations in the factors involved in servo shoe brake design can be investigated, and it is hoped that it may consequently prove useful to brake designers.

Abstract
WHILE the technical part of the history of the aircraft gas turbine in Great Britain presents the features of success and failure familiar in technical progress, there is another part of the history which I believe can be described as an unqualified success. I refer to the habit of collaboration which was developed between the several technical teams in my own country, between Great Britain and the United States, and, later, between Great Britain and the British Dominions.
