Dear Boys and Girls, here is an extensive article in French about the (then) massive Rolls-Royce RB.207 three-shaft turbofan "project" which was initially rated at 47,500lbs thrust in Summer 1968's RB.207-3 version. The RB.207 was based on Rolls-Royce's work on the RB.178 engine prototype and was effectively a scaled up version of the then 35-40,000lbs thrust RB.211 which was being designed for installation on the Lockheed L-1011 TriStar. The RB.207 was intended to be jointly produced by Rolls-Royce (75%), SNECMA (12½%) and MAN Turbo (12½%) in a similar collaborative venture to that of Airbus and it only ever had one intended application; the original Airbus A-300 "project".

Development of the RB.207 had lagged behind that of the smaller RB.211 after the latter engine was selected by Lockheed. No examples of the RB.207 were ever completed......

The article comes from the 15th September 1967 issue of Aviation Magazine International......

See my comments on the RB.178 post. The RB.207-03 was a .957 scale of the RB.178-51, we were working on both scales at the same time! Slide rules were getting very hot in the Design Office!
