Power Plant Progress

AS usual this September issue is timed to appear on the occasion of the S.B.A.C. Display at Farnborough, and as usual we publish in it a specially commissioned article which is intended to give the background to British achievement in a particular field of aeronautical progress. This year it is a survey of work done on rockets and ramjets, contributed by PROFESSOR A. D. BAXTER and MR S. W. GREENWOOD. It is our hope that our readers will find this extensive article useful, providing as it does a statement of achievement to date in the light of which the latest advances on show at Farnborough can be considered in true perspective.
