Let's talk -9F

 Hello Everybody,

Now that the line is going to go next year, It's a good idea to sit and speculate what the next step would have been. I've said on here before that there is scope to do a 747-9F, but what would this be and what could we have expected to see from such a program?

Bedek has restarted P2F conversions, but is this a sustainable program lasting into the long term? How many new frames are likely, given that the are a few 747F classics still around and going strong. Would the market switch to less efficient engines, given that they can't get big freighters with more up to date ones?

Perhaps this a question that BCA should answer.

Anyways, here goes nothing:

747-9F 

Technical Considerations.

Length: Longer than current 747-8, may require strengthened wing box, up to80m total length or longer.

Wingspan: Same as current 747-8, but extra wingspan would be a boon.

Height: Same as current 747-8.

Additional Capacity: at least 2 more pallets on the maindeck and 4 in the underfloor hold.

MTOW: In Excess of 1 million pounds.

Engines: Up rated engines perhaps in excess of 69,000 lbs x 4 engines. Overkill? dunno.

Gear: Strengthened Landing gear with larger tires.

Range: Less than current 747-8F model, 3500Nm worst estimate, but can be extended with underfloor tanks

Other Considerations:

Field performance

Wake turbulence category

Suitable Airports. (Are we looking at a repeat of the A380 here?)
