Boeing: New Enclosure ‘Keeps Us From Ever Having a Fire’


By Charles Murray – The Boeing Co. took the issue of 787 battery fires head-on last night, definitively declaring that with pending modifications to its lithium-ion battery packs, a “fire can’t begin, develop, or be sustained.”

The key to preventing fires is to carefully control the amount of available oxygen, Mike Sinnett, vice president and chief engineer of the 787 program said. Describing a potential scenario, he explained that the pressure disc in the rear of the enclosure would open after about 1.5 seconds of cell venting. Vented electrolyte would then entrain the air inside the enclosure and “take it overboard… So as long as we keep the vented air out of the battery enclosure, there’s no oxygen to support combustion.” more> http://tinyurl.com/cp5q43s
