  • In this fascinating and enlightening video, we will explain the process of how the most powerful airplane engines are built. We will explain the process of making them, assembling them and how they are made. We will dive into the world of airplane engines and talk about the Rolls Royce XWB engine, GE9X engine, Pratt and Whitney F119 engine, Rolls Royce F130 engine and others. This video will be of interest to aviation and airplane engine enthusiasts. Watch this video till the end and we will tell many interesting facts about engines and aviation.

    As a former Navy Jet engine Mechanic I worked on Pratt&Whitney TF-30 P408 engines in the early 70s.

It was a long and tedious posses and sometimes you had to use a mirror to see what your doing. Especially the combustion cans that ignited the fuel. I don't know maybe standards have changed since the 70s or are different for commercial aircraft.

    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.

      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.

      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 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.

    • @andresoteroeirasgranda5870
      @andresoteroeirasgranda5870 Před 11 měsíci

      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.

      @@dasdasdatics420 What an advantage would have a 2stage fan have? A turbofan is the more effective the more mass flow can be moved backwards with the least speed difference between fan inlet and fan outlet. That can be achieved with a 1 stage fan. A 2nd stage would not add thrust but extra weight. If you split the thrust between two stages counter rotating you need either a gearbox or two separate low pressure rotors, again that means extra weight and complexity. If you understand a little bit about turbofans you'd understand.

      Contra rotating fans have been proven to increase the airflow with less loss of efficiency and using lower fuel cost.
      The royal navy use it in the Gannett for extended flight time and the Russians use it to power their strategic bombers.
      Such a system can prevent a condition similar to a propeller in the water called cavitation.
      Also, the design includes the use of a ducted fans which further enhances the efficiency of the fans.

      @@dasdasdatics420 Propellers like on the Gannet or Tu-95 aren't the same as fans. You can't get more thrust out by simply adding a stage. The fan needs power which comes from the low pressure turbine. For modern wide body aircraft fans we speak in the ballpark of 40-60 MW. Modern fan stages use all this power to create propulsion with very little efficiency losses. Again, what do you expect would another fan stage do? More thrust would need more power, which the core engine needs to produce in the first place. Also, the flow characteristics of two counter-rotating fans aren't trivial. You can expect huge losses by turbulences and a lot more noise. Which btw. is quite significant with counter-rotating propellers, too. Don't you think someone would have come up with a counter-rotating fan if it would make technical sense?
