Detecting Fires in Airliner Cargo Compartments

06/17/2005 10:00 AM

Sandia National Laboratories, the Federal Aviation Administration (FAA), and NASA's Glenn Research Center have joined forces to improve the accuracy of fire detection systems in aircraft cargo compartments. False alarms occur about 100 times more often than alarms triggered by actual fire sources, resulting in costly and potentially dangerous emergency landings. Sandia's contribution is a computational fluid dynamics (CFD) model that accounts for heat, mass, and momentum transfer.

False Fire

06/17/2005 11:06 AM

Uhhmmm.... if there is a 100% detection rate for an actual fire there will have to be a decent number of false alarms. However 100 to 1 is an obscene rate of failure. This should have been reworked years ago.
