Re: GE, Safran announce new airliner engine for the mid 2030s

Someone please help me with the blade-out requirements for open rotors. I always assumed that open rotors would be certified as propellers, which do not require armor for the case of blade failure. But many posters assume they will be certified as turbo-fans, which do require such armor. Has the FAA...

Re: "Delta's 757s are their biggest liability"

If the 753 is really the lowest CASM narrow body Delta has .. then Delta is very likely making money on the aircraft and will keep them. If the A321NEO is really a lower CASM, then eventually Delta will replace the 753s with that. I would wonder if the optimal fleet isn't a bunch of A321NEOs, plus s...

Re: Will GE’s XA100 adaptive combat engine transform the F35 ?

It's too bad this engine won't be available for the F-35B. That's the most payload limited version. A small increase in maximum thrust would generate a large increase in payload. The reduced fuel consumption would also generate an increase in payload.

I saw the article as well. Not sure why they are saying 45k as a 10% increase over the F135 (43k) would be 47.3K. Going from 43k to 45k is hardly worth mentioning. That's even less than the planned F135 upgrade. As the F135 was shown years ago to be capable of a 50k rating, the XA100 should most ce...
