| Title: | Interlaboratory Comparison Of The Potential Heat Method | ||||
|---|---|---|---|---|---|
| Author: | D. Gross | ||||
| Abstract: | Quantitative measurements of the total heat release from weight selected building materials were made during an interlaboratory study of the Potential Heat Test Method. Statistical analysis of the results indicates that a higher degree of variability existed among the nine participating laboratories than would be expected of a single laboratory performing standardized oxygen bomb calorimeter determinations of the heat of combustion. It was noted the majority of laboratories tended to rank the materials in the same order, or in an order, which could be made the same by a ranking change of a single materials | ||||

| Title: | Evaluation of a Thrustmeter for Measuring In-flight Thrust of Turbojet Engines | ||||
|---|---|---|---|---|---|
| Author: | Robert F. Salmon | ||||
| Abstract: | An airborne type thrust measuring instrument was developed and subsequently tested on both a General Electric J79-GE-8 turbojet engine mounted on a thrust stand in a laboratory altitude cell and a Pratt and Whitney JT3C-7 turbojet engine aboard a Boeing 720 aircraft. The thrust meter system using measurements of internal engine pressures, ambient altitude pressure and a total air temperature, computed engine gross thrust, net thrust and percent of maximum continuous rated thrust at the operating flight condition. Laboratory tests indicated that : (1) the gross thrust value computed theoretically from the measured pressures were within _+2.0% of the thrust stand measured gross thrust (2) the thrust meter gross thrust values were within _+3.0% of the thrust stand measured values, (3) the net thrust values of the thrust stand measured net thrust, and (4) the thrust meter net thrust values were within _+4.2% of the thrust stand measured net thrust. The gross thrust computer module malfunctioned for a series of tests at a simulated altitude condition of 40,000 feet and Mach 1.2. Flight test results indicated that the system functioned properly abroad the aircraft and was responsive to small changes in engine power setting. The thrust meter gross thrust and net thrust values agreed with the computed gross and net thrust of the engine within _+2.2% and _+2.8% respectively. In measuring net thrust during the flight tests, some difficulty was encountered in obtaining consistent static pressure readings at the compressor inlet station thus causing errors in the computation of ram drag. |

| Title: | Characteristics Of Fire In large Cargo Aircraft | ||||
|---|---|---|---|---|---|
| Author: | Julius J. Gassmann | ||||
| Abstract: | An investigation was made to determine the requirements for protecting large cargo aircraft against in-flight cargo fires. Tests were conducted within an instrumented fuselage of a large cargo aircraft using ordinary packing material as cargo. These tests demonstrated the need for suitable means, air-flow shutoff controls and adequate insulation properly installed. |

| Title: | Smoke Produced By Burning Aircraft Finish Materials | ||||
|---|---|---|---|---|---|
| Author: | D. Gross, T.G. Lee, J.J. Loftus | ||||
| Abstract: | Smoke measurement and an indication of the concentrations of some toxic decomposition products resulting from open flaming and smoldering combustion of 15 aircraft finish materials are reported. Charts and tables are included to facilitate estimating approximate smoke and gas concentration which might exist in aircraft during an assumed fire exposure. | ||||

| Title: | Dwelling Unit Burnout Tests in Pratt Institute Test Building | ||||
|---|---|---|---|---|---|
| Author: | D. Gross | ||||
| Abstract: | Results are reported of three burnout tests in an experimental test building, using a wood crib fuel load of 6 lb/ft and a structural design load radiation, smoke, gas composition and deflection. A discussion of the fire performance of materials and methods of construction, and conclusions with regard to specific fire-protective objectives are presented. | ||||
