NASA Armstrong Flight Research Center recently upgraded the foam fire suppression system for the hangars in our Research Aircraft Integration Facility. The safety system uses high expansion foam, which contains less water and chemicals making it more environmentally friendly. The foam is used to help control damage in the event of a fire and prevent the loss of any aircraft. This video shows the new system being tested in the empty hangars to ensure that the consistency of the foam is correct and that it disperses quickly and evenly enough to suffocate a fire.
