The B in the RB engines refers to Barnoldswick in Yorkshire/Lancashire were the fan chords are made. Rolls Royce made the first stage rockets for the Blue Streak rocket project which was cancelled.
The RB designation goes as far back as WWII and the RB.23 Welland engine. which was Rolls-Royce's version the Whittle W.2B/23 engine that was being made by Rover. R-R took over the manufacture of the W.2B/23 from Rover, together with the Rover factory at Barnoldswick, in 1943. And any of R-R's old hands at Derby, where the company is invariably referred to as Royce's, will almost certainly tell you that the 'R' stands for Royce, not Rolls. PS You committed a capital offence: you omitted the hyphen from Rolls-Royce.
The composite fan blades were first used by Rolls-Royce on the RB211 engines. GE had to wait for the patents to lapse before they could copy the design. The RB211 E4 was way ahead of the competition on fuel efficiency etc. Modular built engines were also copied from Rolls-Royce, they were originally designed by Bristol Siddeley, a manufacturer taken over by RR. The Olympus used on Concorde and the Pegasus used on the Harrier were Siddeley’s designs. RB stands for Rolls-Bristol.

@@robertcook2572 The biggest thing is their is no criteria that is the best for all applications. Airlines want fuel efficiency they don’t care that much about total size or thrust ratio vs cross-section. Militaries cares about thrust/lb and cross sectional area.
@christophercook723 When I was in the Air Force we had Pratt and Whitney along with Allison engine's as well as GE and they were for a time on top but since the use of the High Bypass engine's put out by GE, it just took off and most engine's used today on commercial aircraft are so much more efficient. But you are right about Pratt and Whitney.
Really high NOX emissions though... 27:1 compression ratio, super lean burn with really high burn temps makes for a very efficient engine. But super high NOX, at a time where the UK is restricting cars that emit high NOX from entering big cities like London.
Thays true. Unfortunately there no way today to avoid high NOX production in a gas turbine. Zero NOX would produce more than 2000 C in the first stage of the turbine and there is no material that supports this temperature together with the extreme centrifugal force. Maybe in the future.
@@andresoteroeirasgranda5870 The stoichiometric temperature limit of hydrocarbon fuels is about 1870C. Gas turbine manufacturers have been thinking about how to get there for 70 years.
@@andresoteroeirasgranda5870 It is wrong to talk about "compression ratio" in gas turbine engines. What the compressors are designed for is "pressure ratio". Compression ratio is the ratio of maximum to minimum volume in the working chamber of a positive displacement machine. Pressure ratio is the ratio of absolute pressures at the inlet and outlet of the compressor.
Exactly. Unfortunately then we have 2700 - 2900 C. There are 2 solutions: gas dilution or heat intercooling with the exhaust gas. The first solution is used today and produces NOX. The second one is not used and would not produce NOX. Is difficult to make. You have to cool the combustion gas with the "used" exhaust gas. That will reduce the first stage temperatura up to aprox. 1300 C. The heat absorbed will then reheat the exhaust gas giving the chance to produce more power extraction from the same fuel. May be in the future will be done. Have a good night Andy. @@andyharman3022
