Fire Extinguishing Studies of the Northrop F-89 Powerpplant |
| Author: |
Allen V. Young, |
| Abstract: |
A study was made of the control of in-flight turbojet powerplant fires by conducting full-scale tests on the F-89 fire extinguishing system. The early phases of this study showed that the F-89 fire extinguishing system was ineffective in extinguishing fires of low, as well as high, intensity. Seven modifications of this system wee tested in an effort to accomplish successful extinguishment using bromochloromthane in a perforated tubing system. Considerable improvement in extinguishment of fires was accomplished but to warrant acceptance of the system. |

Fire-Extinguishing Studies of the Northrop F-89 Powerplant |

| Abstract: |
A study was made of the control of in-flight turbojet powerplant fires by conducting full-scale tests on the F-89 fire extinguishing system. The early phases of this study showed that the F-89 fire extinguishing system was ineffective in extinguishing fires of low, as well as high, intensity. Seven modifications of this system wee tested in an effort to accomplish successful extinguishment using bromochloromthane in a perforated tubing system. Considerable improvement in extinguishment of fires was accomplished but to warrant acceptance of the system.
A high-rate-discharge system then was considered as a possible means of providing effective extinguishment. A high-rate-discharge system, consisting of a manifold and distribution lines, was developed which effectively extinguished all fires ignited inside the engine bay, including those of a size which consumed all oxygen in the cooling air. Dibromodifluoromethane was found more effective than bromochloromethan as the extinguishing agent. |

Evaluation Of The Fire Extinguishing System On A Modified PBY Airplane |
| Author: |
Paul R. Dierdorf, James E. Damaree |
| Abstract: |
As a result of request by Region 3 of the Civil Aeronautics Administration, Kansas City, Missouri, a modified PBY aircraft, designation N19Q, was flown to the Technical Development Center, Indianapolis, Indiana, on August 19, 1957, for evaluation tests of the fire extinguishing system. Two flight tests were conducted, one under takeoff power and the other under cruise power conditions. Extinguishing agent concentrations were measured by means of the Statham Model GA-2A portable gas analyzer. This instrument is capable of recording the concentrations and duration of the discharge of the extinguishing agent while the aircraft is in flight. A recorded agent concentration of at least 15 per cent, for duration of � second or longer, is required to assure that the extinguishing system is adequate. |
