Boeing to re-engine the B737

[RoMax]

The look may go in the same direction (altough the upper part is much more blended and the lower part is much more "raked" like on the 787/748), that doesn't mean it's the same technology. But indeed it's probably/maybe based on the MD-11 winglet. But even if that's the case that wouldn't be such a suprise as the MD11 design is in the hands of Boeing. The MD-11 may have brought up the idea that a "double" winglet could have good advantages for the 737. The blended part of the winglet has advantages on the shorter routes, while the raked winglet has more advantages on the longer flights. The combination offers more fuel savings than just one of them.

I know MDC was merged with Boeing and thus all technical data also went to them. They even renamed aircraft types.

I just wanted to point out that they used an idea of over 20 years ago and made it more blended as to update the design.

A Boeing 737 project engineer said today that the new 737MAX winglets will add a "couple of inches" wingspan but crucially they will still be within ICAO category C. The new 737MAX winglets will be based on Boeing technology, not AviationPartners. They will include some benefits from the 787 raked wingtips.

See on this picture how it will look: http://www.newairplane.com/737max/

Just to note; it is Aviations Partners Boeing inc. these days, a joint venture between Boeing and Aviation Partners.

So I think it's safe to say that it's APB 's version of the MD11 's winglets.
Hey, maybe they can retrofit it to the MD11 also.

Boeing MAX update

With the design frozen next year, a first flight planned for 2016 and deliveries to customers beginning in 2017, Boeing says it is well on the way with the 737 MAX. The aircraft is very much a subtle development of the NG series 737, itself an update of a product that first flew in 1967, 45 years ago. Randy Tinseth, Vice President Marketing, has been in London updating the media regarding the new plane.

What Boeing is hammering home is the efficiency of the aircraft, both in terms of fuel burn, claimed to be 9% less per seat than the future competition, the reduced noise footprint, and a number of significant engineering improvements. Passengers will also benefit with the new Boeing Sky Interior.

The sharp-eyed will notice a revised tail design, the Advanced Technology winglet, and of course the engines themselves, larger than anything hitherto on a 737, but cleverly mounted in such a way that the aircraft hull remains in the same position above apron level.

Boeing emphasis that the current NG series has the best reliability of any aircraft in current service with a 99.7% dispatch record (within 15 minutes of scheduled time).
