including carbon fiber composites

Hopefully not designed by that recent sub company disaster.

Boeing is a textbook example of management trying to be a model of DEI support. If you don’t have math skills, you can’t be an engineer, well you can, but not one who I’d trust building planes or bridges...

Looks more comfortable than a People’s Express flight I was on from O’Hare to Hartford in the 1990s.

“Why not just take the Concorde specs and work from there?”

Horrible fuel burn per seat mile.

Huh? Read that sentence you wrote again and think about how silly it is. Was there a Neanderthal space program 10,000 years ago that I’m not aware of? Did they also have iPhones because, “If it had been possible, it would have been done long ago?”

You gonna talk to me about silly, but, one can't get any more silly than what you just said.

iPhones? Neanderthal space program?

How 'bout concentratinig about what we're talking about? Sonic booms and the 'new' supersonic planes.

We've know about supersonic planes for a long time, and we've known about sonic booms for about 80 or so years. So, why didn't they do something about them a long time ago, since they've been hurting people's ears for that long too? If it had been easy, they would have 'fixed' the problem a long time ago. But, it ain't and you still cannot defy physics. Work-arounds" ? Perhaps, but, I still don't see those new planes flying over land any time soon, unless they do it below the speed of sound. Notice they're still trying to work on the problem. So, iPhones? Neanderthal? Think again.

The F-22 engine was most of the equation but the key point was the JP-8 +100 fuel that was developed to allow for the higher temperatures without having the fuel coke.

“Carbon fiber is strong in tension, weak in compression.”

I’m wondering how using a monocoque technique would change those dynamics.

My main experience is with carbon fiber windsurfing equipment and bicycles. My 12 pound road bike frame has 30k+ miles carrying my 225lb butt around with no issues, and when monocoqued windsurfing booms came out I stopped breaking them.

With the success of the test, I read that it is laying the foundations for the commercialisation of Overture, Boom’s production aircraft that will carry 64-80 passengers at Mach 1.7 (1,304 mph). A typical airline travels 547–575 mph. Overture will be able to fly from New York to London in half the time—3-1/2 hours.

Stresses on a bike frame are a bit more complicated than on a pressurized tube.

Seems to me:

The seat tube, forks, and the head tube would be in compression, lengthwise (not from outside pressure like a submarine hull)

The top tube, down tube, and stays would be in shear and tension.

In the submarine application, the hull tube is in compression on the thickness of the hull. In your bicycle, the down tube and forks (for example) are in compression along the length of the tube.

I saw "XB-1" and thought:

My bad.

Yes. I remember when Carter cancelled it.

I liked the Punisher intake covers in that photo.
