Fuel Efficiency

I know American Airlines is suffering badly because of fuel costs.  It will take a great engineering feat to bring airplanes into the fuel efficient era.  It will involve many disciplines.  I hope they can pull it off!  Wing design, engine design, electronic controls, fuel mixtures, and who knows what else, will make it happen.  I am sure they have things in the "wings" that will surprise us all!

Interesting they clipped off the wing tips in their picture while mentioning they were developing new tips.  I wonder what the tips will look like.

As I recall, the 787 offered a 20% fuel efficiency boost over the 767, but I believe it required the biggest engineering effort in the company's history. Given that, 10% to 12% seems pretty good.

Aerodynamic vs. Weight Improvements

From the article, I got the impression that the majority of the savings were aerodynamic related.  I did see weight reduction mentioned also (for the fly by wire change), but the design changes didn't seem to focus on removal of weight.

From the picture and the article, I also noted the larger engines that are now directly attached to the wing (which appear to be a noticeable change from the older 737's that I remember when I was younger).

You probably know way more about this than I do, TJ. I was just thinking in terms on how inefficient automation devices and vehicles were in the past. So it seemed there must be significant gains to be made one you concentrate on energy savings. As an example, efficient motors and drives are driving down energy consumption 15 to 35 percent. Perhaps Boeing was not so inefficient going into the drive for efficiency.

Rob, I have exactly the opposite viewpoint; I was surprised they plan to squeeze that much more from the design.

I'm a bit surprised the re-design would only yield 10 to 12 percent fuel savings. It seems that number of changes would produce a greater savings. Perhaps the earlier models were already designed for efficiency.

The phablet wars continue. Today we welcome the Nexus 6 -- a joint collaboration between Google and Motorola.
According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.

Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation call this deep learning.
