Today’s invention is a multi-tube fuselage design for airliners.
This would be subject to the same drag force as a conventional wide-bodied jet. Although the bundlebody perimeters would be twice as long in total as that for the conventional machine, the wall thickness in each case could be made half as thick, due to the enormous increase in pressure resistance which comes with narrow cylinders.
Each narrow cylinder would have local space in which to store one’s baggage (ensuring that any terrorist explosions are isolated in effect and that the crew, flying in another cylinder, are better protected).
The narrow tubes would be easier to support in the event of a depressurisation incident.
Aircraft could be much more easily configured, on the ground, by detaching some tubes, to cope with sudden changes in passenger bookings. In addition, the views for all passengers would be improved.
Great idea.
why not creating tubes above each other? This would work as a big vin (right word?)
I also wondered why a plane is cylindrical (OK most space wrt size). If the cylinder is made a bit (1 meter?) bigger in diameter everyone could have a window seat. And of course the cylinder should be able to rotate (slowly) so everyone can get a glimpse from left and right view.

Bigger diameter increases the structural loading, drag forces and probably weight. I suspect that these factors would outweigh the window seat idea’s benefits. I love the idea of a slowly rotating fuselage though. It makes me think that you could have a fuselage with a long cylindrical hole down the middle. This could be both low-drag and super strong -it also offers a good place to fit a central jet engine or a cargo hold.
