That's why I posted the late bit since this contradicts what have been said since the change to take into consideration the fatigue already built into the wings by years of service happened a couple of years ago.
The fact that there is potentially an alternative to single pod or move the location of the pylons is, if confirmed, a new deal.

They are buying eight engines per aircraft. There is no feasible way to arrange them except in four twin pods. Any other arrangement would mean restructuring the entire wing, which isn't in the scope of work.

As much as it's possible it makes sense to keep the aeroelastic properties very close to those of the TF-33's to avoid a full up P&FQ V&V on a 70 year old airframe. Strategic placements of lead or DU are totally worth making sure the moments of inertia and what else are the same, or very close to possible as the old installation to avoid a longish certification...

The more I think of this the more it comes out as a great win for RR.
They've got maintenance monies coming in on these engines for the next 50 years (and thats where you really make your money), they can turn around to any potential customer of the engine and point to a near certain 50 year future in service support of a significant number of engines.

given the weak travel sector, its a great win for RR. Roll on the good enough for a B52 adverts.....

Who knows, maybe it will catch on, maybe re-engine those A380's, 8 has to be better than 4, shirley?

^ Wait! Does anyone seriously use DU for ballast in the 21st century?! Do they hate their lineys?
Yes, it’s not ballast, but rather a flutter weight. When you shift the CG of the aero surface forward of the elastic axis it then acts as a damper for aeroelastic driven vibrations. At least that’s way I remember it, been two decades, but at a high level the point is made.

As for DU it isn’t that radioactive, don’t confuse it with enriched uranium which is a totally different thing.

There is probably not the equivalent of 6000 rounds used as Bob weight in any aircraft. At least not before it got inside the reticule of the beast...
