Chase September 28, AM. It's a little odd to me that they would go with a new engine that has slightly less thrust than the outgoing engine that they started installing in the BH. The efficiency and ubiquity must have been good selling points. Would've been interesting to see how the efficiency of the two engines compares, even if it had to be comparing the civilian variants of the two engines.
I remember seeing the trail of black smoke when the B52 takes off, indicating inefficiency. I thought they might replace the 8 engines with 4 High bypass engines. Food4Thought September 28, AM. So - instead of all of that bother, they just decided to replace engine for engine, or so I had once read. DavidIngram September 28, PM. Definitely, but this solution will get questioned an challenged.
Well, good for Rolls Royce Royce was an early powered flight death. My mistake - It was Charles Rolls who 'bought the farm' by way of Britain's first powered flight fatality. Gregg Eshelman September 28, PM. The engines the B used before the TF didn't have bearing seals capable of holding the oil pressure so under high thrust operation, which came with increased temperatures, oil would blow out of the bearings due to higher pressure used to keep the bearings cool. The early F-4 Phantom fighters also used engines like that.
Rolls-Royce jumped into the re-engining contest before it was even announced, touting its BR power plant—military designation F—as the ideal candidate as early as September Jovie Abaya and SrA.

Despite rumors to the contrary, Isabelle said the Air Force is not looking for substantially better physical performance from the new engines—for example, in time to climb or top speed—although that may turn out to be a welcome by-product.
Arnold W. Bunch Jr. All of those are things that weigh into how we look at this. Hunsicker predicted that within six months—after revelations in the Fiscal budget—the Air Force will have a solid plan about what will need to be done to the B to keep it a credible, safe, and capable bomber for its newly extended service years.

By John A. But the SOJ concept was never put into effect. Photo: A1C Sydney Campbell Despite their age, the Bs have high mission-capable rates, can carry a huge diversity of weapons, and can perform effectively—as long as the enemy lacks elaborate air defenses. Even in a higher-end fight, the B can still launch missiles from well outside enemy air defenses. After decades of combat flying in the harsh Middle East environment, the Air Force embarked on an aggressive program to deal with an insidious problem that steals aircraft performance, greatly increases maintenance requirements, results in higher fuel consumption rates, and increases emissions.
The culprit, the constant erosion and corrosion of high pressure compressor and turbofan blades due to environmental particulates. To mitigate excessive wear, and…. Department of the Air Force policy calls for a decision within 30 days on requests for religious exemptions to mandatory vaccines from Airmen and Guardians within the continental U. The Air Force has already anticipated many of these issues by funding offerors to assess the risks associated with reengining the B and devise solutions.
Ideally, what it needs is an engine that mimics the thrust and dimensions of the legacy engine while offering greater fuel efficiency and reliability. This is a BETA experience.
