Sonic Cruiser Program On The Roll

Tue Feb 12, 2002 9:38 pm

In the past two weeks, Boeing has signed on two subcontracters for work on composite materials and srtuctural work on the SC - Japan Aircraft Industries and Japan Aircraft Development Corp., and today announced another deal with Alenia Aeronautica, an Italian Aerospace company.

It's starting to look like more than just a PR job. As a spotter - I can't wait to see it. Ever since the beginning of the Jet Age, this is the first all-new shape to turn up in commercial aviation since the 50's, with the exception of the Concorde.

Hey, Cfalk:

Is there any truth to the notion bandied about here that the SC will have two regions where efficiency is maximized; one at .98 mach and the other at 1.2 mach?

Somebody told me about there being two "nodes" of efficiency for the design.

I can only confirm that I heard the same thing, namely that the plane will have both sub- and supersonic capacity. The airlines requested this, which is part of the reason the rollout date was pushed back two years to 2008.
It is not enough to be rude; one must also be incorrect.

There really hasn't been a huge amount of progress in airliner design in a long time. Truthfully, airplanes today are just as capable as the ones 40 years ago, although being more efficient, and more automated.

I hope this is the big breakthrough which the industry needs. If it cuts travel times, and also paves the way for future advances in aircraft design which will enable them to go even faster, this will make todays aircraft obsolete very quickly. I hope for Airbus' sake they are studying something like this too!

I've heard the same. Clearly, if the plane is capable of cruising at .98 Mach, it should be capable of going 10% faster or so, if all other planes are an indicator.

As far as the double-sweet-spots, I think it's possible, and it makes great sense if it can be done, although what I heard was more like 1.02 Mach. The plane would fly at .98 over land, and accelerate over water.

*bump*

and fwiw, I found it rather refreshing the the Union rep agreed with the move by Boeing, saying that it was benefical to include those companies early, as Japanese airliners are important customers.
