My earlier posting had my back-of-the-envelope calculations showing that a flat pressure cabin for a blended-body airliner is quite practical and can be designed as a set of intersecting cylinders. As should be expected, a real aeronautical engineer can do better than I can. In the book "Shorts Aircraft since 1900" by C.H. Barnes I came across a picture of a proposed flying wing airliner designed by Geoffrey Hill. He used a "quilted" pressure cabin made up of intersecting spheres. The tension links needed to hold the shape are then slim pillars set in a square array with about fifteen or twenty feet between pillars, with the arched ceiling between pillars giving a very spacious look to the cabin. The design was called the Pterodactly VIII and was submitted to the Brabazon Commission. It had five Rolls Royce Griffen engines with pusher props, and would seem to be made to the same specifications as the Bristol Brabazon. In a large blended-body airliner the average seat will not be as near a window as on conventional planes, to the extent that this is a problem. Each passenger could have a video display screen that could give an outside view as well as being used for entertainment and preflight safety briefings. I have read that it is or will soon be possible to combine the views of several digital television cameras onto a screen. This might allow the plane to have a set of external view cameras giving 360 degree coverage, and each passenger could look in any desired direction by combining the signals in their screen.
