Isn't it amazing how intelligent and great we are at killing each other?? Imagine we used that money time and effort for the good of us, but these damn elites want us at war, to keep us divided and make all the money for themselves and their monopolies
Can never understand how aircraft stay in the air, considering how many parts there are and the complexity of it all. All credit to some very clever people who collectively make it all happen. So many specialist working together.
A rolls Royce XWB engine doesn't cost $140 million dollars. More like $18-20 million for bare engine, and another 5 million for the inlet, mid cowling and thrust reverser.
They can be a lot more expensive over engine lifetime. The lifetime cost of a large commercial jet engine including maintenance is anything from $40 million to $100 million plus depending on the number purchased. Jet engine manufacturing is dominated by the US and UK and the level of engineering that goes into their design and production is pretty amazing.
@@peterd788 I know all too well how expensive modern jet engines are, the engineering that goes into design, build and continuing product improvements, and the operational coats are. Today, engine leasing or Power by the Hour, give airlines a known cost verses rolling the dice and taking the chance the engine is going to live 35-40 thousand hours. All of the manufacturers set fuel burn guarantees.

I worked building jet engines for a couple of years about 45 years ago. Good job but working in a factory wasn’t for me. I assembled JT-8s and JT-9s. I wasn’t using my electronics education.

Todays Efficient Engines are Crap No No Power ,Airlines Want Money So Companies make Low Power Engines , They Only Have Big Size but Not Powerfull compare To PW4000 And GE90 or Rb211
What i would really want to see is not the final assembly line, but places where all these parts are made and how they are made...but trade secret ye ?
It's actually $35 million each for the Trent XWB,the world's most efficient high bypass large engine,based on RR's contract signed in 2007 with Qatar Airways worth $5.6 billion for 80 Airbus A350 XWBs.
I nvr seen an engineering as fascinating as this!! 😆 Not to talk about how you get an airliner in the sky, but how you get that giant engine into the sky!!!

@@nathd1748 No they have not. It's in very initial testing phases and they have said themselves it's not really a priority. They don't have anything to put it one right now anyway.
@John Iii Not a priority??? You talk out of your ass! I'm the one over here with the phone line into the RR workshop and I'm hearing and seeing a completely different picture to what you are getting! The reason behind the fan size at 140" is that according to Boeing, that is the largest engine size they can fit under a 777x wing. So even though GE currently have exclusivity until 2028, RR are building a geared fan that will give them an idea of how it compares with the GE9x and what they can expect when scaled down. For your info, there are currently 4 other engines being assembled with smaller fans that will join the test programme. And IT IS a test programme because they are using the same core across different engine sizes but with a smaller main fan.
@@nathd1748 Take shop gossip for all you want. The truth is is Boeing having so many problems as it it with the 777X development right now as it is, they are not looking for another engine for it. Maybe in 10 years from now it might be an option. And basic fact the number of aircraft it will sell its not worth it for a two engine option. RR developing it is highly likely to be for Airbus and Airbus isn't in any hurry.
@John Iii You have totally no idea mate. I work at Broughton Airfield, so you SHOULD have an idea who my employer is and WHY what I'm telling you is not gossip.
Worth to mention that each fan blade is made of a single crystal of titanium alloy. Being made of a single crystal is to avoid failures originating from microscopic cracks between crystals! … Jet engine! What a piece of machine!!! ❤
It's also not the fan blades that are single crystal, but the high and low pressure internal turbine blades. (the smaller ones inside the engine on the hot side)
@@harryblack8686 They also have air passages embedded throughout the blade so cooling air can be blown through. I've filmed the whole process from lost wax casting to coming out of the furnace-absolutely fascinating.

I think no longer should we speak of "Jetengines" when we consider "turbofan-engines". These are no longer "turbojets" as in the beginning . Nowadays they have enormous blades so we can almost speak of Propellers.
