@FASRP...you are well off the ball....
try:- 250 people spent , collectively, 50,000 hours , two at a time, in any one of fifty rooms.
150 of them died during their occupancy
That'sthe scenario at "grounding"
Total in-service fleet=50 each containing 2 "serviceable" batteries.
"dead" batteries replaced:- 150
Total hours flown, 50,000 divide total stock into hours flown and you get an average service-life of
200 hours
@ Seth Welcome !...As you'll see, this lot don't take prisoners!
but a great place for an intellectually stimulating debate.
I' m presuming you meant "Hindenberg "? the infamous Hydrogen-filled Airship.
@ Blacksheep. Totally concur with your remarks , re the firebox.
It's a total victorian-engineering , heath-Robinson lash-up.
52 bolts????WTF -it's supposed to vent at ~ 6000 feet cabin-altitude.
The plate-box already has a lip flange....make the sides and back much bigger and fold back on themselves(upwards)....you now have a slot/runner turn a lip down on the front of the lid. When slid home, the lid and case are securely clamped on all 4 sides...a bolt through the 3 thicknesses,say every 3 inches , would stop any bowing and be mainly in shear.. 12 should do all 4 sides.
Re-ceramics....-been saying this for a long time IMHO each individual sub-cell should be fully thermally insulated and fully monitored for charge-discharge.
These people appear to be attacking the problem from the wrong end!
Preventing an out -of -service battery is a much better "fix" than containing the thermal runaway when one does go TU.... No doubt some of the real Boffins on here can accurately calculate just how much heat-energy is disemitted by 32V 70 Ah discharging in an uncontrolled thermal "event".
