would u imagine if one of the people that tell the airplane to come, u know on the ground with those green sticks, got into that engine by mistake. that would be a painful death x 1000

ROLLS ROYCE ENGINES ARE VERY LOUD!
-
@SkyWestCRJPilot YES THEY ARE VERY!!!!!!
-
@SkyWestCRJPilot TBH I'm not realy sure which is louder, maybe the RB211 "buzzsaw" is louder than the Pratts? but I do know that the RB211 was considered quieter, and this was one of the factors that prompted airlines such as AA to order 757s with RRs.
-
RB211s might be more powerful, but they weigh more thank the PW2000s on the 757.
-
No, on the contrary its the RR that is the less noisier out of the 2, its one of the reasons why most of the 757 operators chose the rb211.
-
The PW engine couldn't compete with Rolls on so many levels. The most significant was that the PW engine didn't make TBO. That's bad news for operators like Delta and one reason RR powers the majority of 757's worldwide!
-
yeah, millicha is right, and also the pw2000 series are less noisy than the Rolls Royce rb211 series. That's one of the reasons delta prefers them. With less noise is more comfortable for the passengers.
-
Well Pratt's are safer for the environment and saves like 8 or 10 % more fuel. This particular one is a PW2037 which has 37,000 lbs of thrust which is less than the rb211-535 blowing 40,100 lbs of thrust. But there is another version, the pw2043 which has 43,000 lbs of thrust even more powerful than the rolls royce. United uses that version. In my opinion PW's are more efficient.

Most B757 operators use the Rolls engines. The Rolls Royce is far superior.

Those are Pratt and Whitney PW2000 engines.
Delta was the launch customer for those.
