Re: Why is the A343 "underpowered"?

The CFM-56-5C was tested to 36,000+ lbs and I'm sure it would not have taken much to certify it at that rating. Obviously Airbus didn't feel that they needed to.

Re: Delta orders 100 P&W powered A321neo aircraft, plus 100 options

Re: [Hindsight] GE90 powered A330

Well, considering the GE90-90B (90k thrust variant) weighs 17,400 lbs and the GE CF6-80E1 weighs 11,200 lbs, I can see why Airbus would be rolling their eyes. Only a serious stretch of the 333 could make that weight penalty worth the fuel burn savings. Taller landing gear may also be required...

Re: Boeing officially forms program office to flesh out 797 plans

Where is this "767-400 has taller landing gear to fit the PW4000 94-inch fan" stuff coming from? The taller gear has absolutely NOTHING to do with the engines. The 767-300 uses exactly the same size engines (93 and 94-inch fans) as the 767-400. The only difference is the thrust rating, and...

Re: Airbus weighs response if Boeing launches new mid-market model

The only course that really makes sense for Boeing is to address MOM with a version of their 737 replacement (NSA). This shouldn't be too hard as the optimum size for both the 737 and 320 keeps moving up. A318, A319, 737-600/7 are basically non-factors.. NSA will probably start with 738/A320 size an...

Re: Boeing officially forms program office to flesh out 797 plans

I'd like to see a 767-200A NEO (GEnx-2b). That would have real promise for the MOM role. Forget the -300. Too big (and too ugly in my opinion)

Re: Qantas considering 777-8 or A359ULR to replace 744ER's to fly SYD-JFK and SYD-LHR non-stop

The 777-8 is clearly too large for this mission, which calls for 300 seats, not 365. On the other hand a 772 length 777X would be perfect for this mission and should be able to meet all Qantas requirements without MTOW increases or a central bogey. It would also have superior CASM because its not ca...

Re: 748 or A380 Bomber Aircraft?

Or just use the An-225 for 560,000 lbs of bombs over a longer range (still short compared to typical bombers).

Stratolaunch would be perfect however for one huge 500,000 lb thermobaric bomb.

Re: Northrop Grumman B-21 Raider Production And Delivery Thread

Given that the F135 has 28,000 lbs dry and will certainly get a larger fan for a better subsonic efficiency, I can see the derivative for the B-21 having 36-40,000 lbs thrust.

Re: Qantas considering 777-8 or A359ULR to replace 744ER's to fly SYD-JFK and SYD-LHR non-stop

I still think the best aircraft for this role would be a 772 fuselage length for the 777X, call it the 777-7X. The 772 can already seat 300 in 3 classes. With the wider interior it would have even more space. The 777-8 is too big for this niche. A 777-7X would offer superior performance to either t...

Re: Airbus weighs response if Boeing launches new mid-market model

Based on 767-200 non-ER max TO weight and engine thrust, I'd think a 150 ton MOM would need at least 50,000 lb engines unless the wing area is substantially larger than the 767's 3050 sq ft (which of course would add more weight)

I'm all for an A358 ULR (especially if it gets all the A3510 mods), but I had thought that the original A359 ULR proposal with the A3510 wings, etc had the range/payload required for this mission?

Re: With the 747-8i all but dead, can the 747-8F gain significant orders as a result of earlier 747 freighters retiring?

They won't stop producing the 747-8F until there is a real one-for one replacement, which the proposed 777-8F is not. I'll bet even money that if they threaten to close the line before then, there will be a flurry of orders to "get one while they can", ...resulting in continued production.

Re: New TU-160

Supposedly the new NK-32-02 engines will add 1000 km range and more significantly, enable cruise at over 60,000 ft as opposed to ~50,000 ft for the current aircraft. That would require a significant increase in thrust (probably to 65,000 lbs or more), but so far there has been no information forthco...

I doubt it was a NT-43A if it was outrunning other 737's, especially with all that added drag from the sensor blisters.

Re: Could anything save the 747?

Saving the 748 (beyond the -8F) would in my opinion require a GEnx-2b using GE9X technology and giving 5% better sfc, a reduction of OEW to original promised spec (466,000lb) or lower, and full implementation of Project Ozark improvements (higher MTOW, improved wing-body fairing, improved wingtips. ...

Re: Could anything save the 747?

The disappointment that is the 747-8 program is a direct result of two factors: 1.The failure of GE to provide an engine that met promised specifications (and still doesn't, by the way) The -2b67 was like 4-5% over spec at service entry. 2.

Open rotors are fascinating. Just remember the slower cruise speed than a GTF. They're benefit is they give you a higher bypass ration without the weight of a nacelle.
