Thank you very much for your comments and questions. Most topics which have been raised here I discuss in a longer presentation of the project which can be found here:
It's primary focus is to explain the general train of thought which leads to the configuration to people who are new to aircraft design.
Just a few comments on some of the topics which were mentioned here:
- The distance passengers sit from the center axis is 13m. There were several studies and simulations back when the BWB was a hot topic and this distance of 13m was found to be acceptable for the cabins.
- Turning the seats at an angle to the flight direction is already done in business class cabins today. On this design here one could maybe even turn the seats back to the flight direction some degrees so that in the end it would only be 14° or so.
- Fuel can be stored in the outer wings and a center fuel tank, so that the CG does not move so much when fuel is burned.
- The static margin of the design is roughly the same as it is on conventional configurations.
- Span / passengers are the same as A350 so it should be compatible with conventional gates. There is even no wing in the way of any airport ground vehicles or gangways.
- This is of course an interesting topic, but believed to be easier than for the BWB because the Flying V planform has more equal lines with the cabin. It seems unlikely that the whole 40 meters of one cabin side are blocked (all that is dangerous: engines, fuel... is on the inside of the V). But it has to be studied and looked at.
Comparison to reference:
- In this work the design was compared to the A350. It looks like there might be a serious benefit in performance. I also discuss this in the presentation mentioned above.
