Evaluation Of Identification Beacons For Airport Emergency Vehicles |
| Author: |
Bret B. Castle |
| Abstract: |
The purpose of this effort was to determine the effectiveness of several newly developed identification beacons for airport emergency vehicles. Fourteen different light bar configurations were tested on the National Aviation Facilities Experimental Center (NAFEC) airport during various environmental conditions and human appraisal of the different combinations was performed for suitable airport use. The results lead to conclusions as to which signal characteristics are most effective for use within the aircraft movement areas of airports. |

Aircraft Fuel System Tests with Gelled Fuel-Flowmeter Calibration Fuel Boost Pump and Jettison Tests |
| Author: |

| Abstract: |
The feasibility of using gelled fuel (nominal 250 centipoise viscosity) with full scale aircraft fuel system components was investigated. Tests indicated that turbine-type flowmeters are suitable for measuring flow rates with accuracies of 1 percent. Jettison and fuel feed operations were conducted using a B-57 wing fuel tank. Approximately 3 percent more gelled fuel than JP-5R remained in the tank after �emptying� the tank in both boost pump and jettison tests. Flow rates and times to �empty� the tank were significantly poorer with the gelled fuel when compared to the results obtained with the JP-5R fuel. The gelled fuel tested is considered unsatisfactory because of its instability in storage, causing wide variations in viscosity. |

| Title: |
The Influence of Engine-Ducted By-Pass Air on a Burner-Can Burn-Through Flame. |

| Abstract: |
Tests were run to determine the effect of by-pass air flow on a burner-can burn-through flame. A simulator was developed to produce a burn-through flame external of a J-57 engine. Bleed-air from a J-57 was ducted and used as by-pass air during testing. Temperatures of the outer duct wall were monitored. A large decrease in temperature was noted with air flow through the by-pass duct. |
