Airbus recently announced three concept aircraft for commercial use, powered by liquid hydrogen, with an ambition to have the plane in operation by 2035.
From what I can tell, the turbofan variant is in the same segment as the current A320, albeit with somewhat reduced range.
Considering hydrogen powered planes, the challenge is to carry enough fuel to make it compete with kerosene.
There are several options, and from this question it seems 3 options stand out:
- Cryogenic: storing the fuel as a liquid
- Compressed: requiring heavy and strong fuel tanks
- Hydrides: bind hydrogen with another substance and release upon heating
Airbus intends to go with option number 1, that is storing the fuel liquid and cryogenically behind the rear pressure bulkhead.
The unbalanced weight distribution storing not only the fuel, but assuming also heavy tanks and cooling equipment in the far rear of the plane seems like a maneuverability issue to me, with a pitch-up moment from the shifted weight balance.
What measures can be taken to mitigate the (assumed) adverse handling this creates?
