February 12, 2021, ©. Leeham News: After covering the basics of fuel cells last week in our hydrogen airliner series, we now look at what type of system to choose for aircraft propulsion and onboard systems power.
We analyze the propulsion side this week.
February 5, 2021, ©. Leeham News: Last week, we started the discussion around fuel cells as a source of electric energy in airliners. We went through the principle and asked some vital questions.
Now we look at different types of fuel cells and for what applications these are suited.
January 29, 2021, ©. Leeham News: Over the last weeks, we looked at Center of Gravity (CG) problems with rear fuselage liquid hydrogen tanks as used in Airbus’ ZEROe turbofan airliner concept. We can conclude that the CG shift is manageable for a short-range aircraft (range below 2,000nm).
Now we spend the next Corners diving into hydrogen fuel cell technology and how it can benefit a hydrogen-fueled airliner.
January 22, 2021, ©. Leeham News: In last week’s Corner, we looked at how the hydrogen consumed in the rear fuselage tanks changes the airliner’s Center of Gravity (CG).
Now we discuss how this change of Center of Gravity, limiting the aircraft’s load flexibility, can be mitigated with different concepts.
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.
January 8, 2021, ©. Leeham News: In our Corner before Christmas we discussed the hydrogen tank placement at the rear of the aircraft for Airbus’ ZEROe concept turbofan aircraft.
We now calculate how the weight transfer when emptying the tanks in the rear affects the ZEROe’s efficiency.
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.
