Bjorn’s Corner: The challenges of hydrogen. Part 20. Hydrogen airliner weight shift

By Bjorn Fehrm

January 15, 2021, ©. Leeham News: In last week’s Corner, we looked at how hydrogen consumed in the rear fuselage tanks of Airbus’ ZEROe concept affect the airliner’s efficiency.

Now we look at other aspects of the rear placement of the tanks.

Bjorn’s Corner: The challenges of hydrogen. Part 18. Airliner hydrogen tank

By Bjorn Fehrm

December 18, 2020, ©. Leeham News: After discussing the risk-reducing research programs we need to do before a program launch in 2027, we focus the next Corners on the hydrogen airliner’s biggest problem, the liquid hydrogen tank.

In this Corner, we start with the placement and discuss how it affects aircraft performance.
