If it wasn't for the RB211 we wouldn't have engines such as the Trent 500 for the A340-600 or the Trent 800 for the 777s. The main 'three-spool' architecture derived from the Rolls-Royce RB211 made this happen. The world's first three-spool gas turbine engine was the RB.203, hence the RB.20(3) in the name, it means three-spool, this advancement in engines is revolutionary.
too bad everyone else in jet engine manufacturing stole Rolls Royce's methods for growing complete turbine blades. a lot of people don't know that turbine blades are grown from a single crystal of metal for extra strength. they are even hollow inside for air cooling.
Those little bots... It's fun to think of the good possibilities now, but you know there's going to be a world where those things are dangerous almost beyond imagining.
 
The greatest waste of efficiency is where the internal turbine has to force its exhaust gas back into a bladed wheel to spin the large fan blades.
Only through this fan is the flow of cold air for the propulsion realized. There are better solutions and they would reduce fuel consumption by almost half.
Fascinating video! Could have been so much longer. BUT!!! It was NOT a turbojet! Turbofan. I'm aware of my pedantry, but in this case there's a hell of a difference.
It’s a little difficult to even watch a video when the title doesn’t even describe it accurately. “Turbo fan” and for those who think myself and others are splitting hairs....there is a HUGE difference.
