HIGH SPEED DETECTION AND CONTROL OF FIRE IN SOLID PROPELLANT FUEL.
Abstract
The object of this work is to determine whether and how fire detection and control of burning are possible and practical where the hazards of high-energy, rapidly burning, solid propellent expose the interests of the Bureau of Yards and Docks. The work done by the Factory Mutual Research Corporation during the past 12 months began with the knowledge that certain detection systems can recognize and respond to fire, including propellant fire, well within 5 milliseconds. This speed of response was considered to be satisfactory since it would amount to only a small fraction of the total time required to apply any extinguishing agent to a fire. Currently, a test program is in progress using 10 lb, hollow cylindrical samples of Polaris A3 propellant. Complete extinguishment of propellant fire at atmospheric pressure and after various pre-burn intervals up to 20 sec was accomplished and documented. (Author)
