It may be too hard to do a good retrofit. If you basically have to tear the entire plane apart and rebuild and recertify it to put batteries in the right places, maybe the costs aren’t worth it for potential customers.
I know many planes use their wings as fuel tanks but given the weight of batteries maybe that doesn’t work.
I agree it’s interesting. Not a small undertaking.
Generally all the weight of the fusaage has to go through the wings anyway so it is structurally more efficient to put weight on the wings in the first place.
And they do that with fuel?! Neat!
Yup.
On a 737 they can put about 8k pounds per wing.
Even little planes like Cessnas have wing tanks.
