Boeing's new CEO orders rethink on New mid-market jetliner project
LONDON/CHICAGO (Reuters) - Boeing Co's <BA.N> new chief executive has sent the aerospace giant back to the drawing board on proposals for a new mid-market aircraft, effectively shelving in their current form plans worth $15 billion-$20 billion (www.yahoo.com) Más...Sort type: [Top] [Newest]
Bring the 757 back to the table pretty please?!
- I for one, welcome a 757 NEO. Naysayers have a kneejerk reaction - oh gosh, Boeing destroyed the original production tooling, so don't think further. But a wise CEO would ask his staff- How much development time and development risk, to reconstruct tooling for a known proven 757 airframe ? And power it with efficient engines. Many of the existing 757 fleet is powered by Rolls engines. I bet Rolls would be happy to offer engines for a 757 neo. Would certainly be less risk and faster time-to-market than NMA
From my understanding, the main problem with a 757 re-engine comes down to aerodynamics and weight. Although there may be efficiency improvements from a GTF conversion, there is no changing the fact that it is an old airframe and would already be well behind the operating economics of the A321XLR.

The 757 basic airframe goes back to the 707, 727 and 737; same barrel, pure Renton product.
This.
It appears that I’m being downvoted around here, but bear in mind that it’s not my fault that the 757 is as heavy as it is, nor is it my fault that it is aerodynamically challenged compared to newer, more advanced designs.
Sure, it was a cool plane back in the day. Now it is obsolete. Again, nor my fault. Get over it.

A new 757 would need a much lighter airframe and systems.
The old 757-200 had a DOW of 60,000kgs (132,000lbs), unable to compete with A321 and their like. So it would need to be some kind of composite narrow body 787 with brand new engines of around 35,000 lbs of thrust.
For performance it should retain an eight wheel MLG and large flaps, to make it able to land and tkof from short runways with its MTOW. That was the beauty of the 757!
