End-zone water injection as a means of suppressing knock in a spark-ignition engine by Rinaldo J Brun ( Book )
3 editions published between 1944 and 1945 in English and held by 4 WorldCat member libraries worldwide
Summary: An investigation has been made of the effectiveness of water injection into the combustion end zone of a spark-ignition engine cylinder for the suppression of knock. Pressure-time recoreds obtained show that injection of water at 60° B.T.C. on the compression stroke at a water-fuel ratio of 0.3 rendered M-3 fuel as good as S-3 fuel from an antiknock consideration. The optimum crank angle for injection of water into the end zone was found to be critical. As the injection angle was increased beyond the optimum, the quantity of water required to suppress knock increased to 3.6 water-fuel ratio at 132° B.T.C. The water quantity could not be increased beyond 3.6 water-fuel ration because of injection-pump limitations; however, a further increase in the injection angle up to the earliest angle obtainable, which was 20° A.T.C. on the intake stroke, continuously increased the knock intensity. The engine operating conditions of the tests did not simulate those encountered in flight, especially with regard to the operating speed of 570 rpm. For this reason the results should only be regarded as of theoretical importance until further investigation has been made

Heat-transfer tests of a steel cylinder barrel with aluminum fins with improved bonding between steel barrel and aluminum base by Herman H Ellerbrock ( Book )
3 editions published between 1939 and 1940 in English and held by 3 WorldCat member libraries worldwide
The finning of conventional cylinder barrels cannot be improved to any great extent except by adding find weight which means, in general, fin width. By a conventional cylinder barrel is meant a steel barrel with steel fins. For in-line engine and in some cases radial engine installations the width of the barrel fins is limited and a possible solution of the barrel-cooling problem is to use preformed aluminum fins on a steel barrel. If a reasonably satisfactory bond between the aluminum and steel is obtained, the heat transfer of the barrel should be greatly improved

Flight and test-stand investigation of high-performance fuels in double-row radial air-cooled engines. 2 - Flight knock data and comparison of fuel knock limits with engine cooling limits in flight by H. Jack White ( Book )
2 editions published between 1944 and 1945 in English and held by 2 WorldCat member libraries worldwide
A comparison has been made in flight of the antiknock characteristics of triptane with a temperature-sensitive blending agent (xylidines) and of the fuel knock limits with engine cooling limits. The knock limits of three fuels were investigated with a 14-cylinder double-row radial air-cooled engine installed in a four-engine airplane. The investigation was conducted at an engine speed of 1800 rpm in high blower ratio with two carburetor-air temperatures and at 2230 rpm in high and low blower ratios with one carburetor-air temperature
The low-temperature solubility of technical xylidines in aviation gasoline by W. T Olson ( Book )
1 edition published in 1943 in English and held by 1 WorldCat member library worldwide
Tests were made to determine the low-temperature solubility of technical xylidines in aviation gasoline. The tests included measuring the cloud point, or incipient separation temperature, at several concentrations of technical xylidines in a 65-octane-number clear gasoline without aromatics and with aromatics added in various percentages up to 15 percent by volume and a grade 130, specification AN-F-28, amendment 2, gasoline. Cloud points were determined as a function of concentration of xylidines in the gasolines described as a function of concentration of xylidines in the gasolines described with an experimental reproducibility of plus or minus 1.5 degrees C
The effect of modified baffles and auxiliary-cooling ducts on the cooling of a double-row radial engine by Stanley L Gendler ( Book )
1 edition published in 1945 in English and held by 1 WorldCat member library worldwide
Tests were conducted in the Cleveland altitude wind tunnel to determine the cooling effect of modified baffles and auxiliary cooling ducts on the rear-row cylinders of a double-row radial engine in the power-plant installation of a four-engine heavy bomber
Fuel-vaporization loss a determined by the change in the specific gravity of the fuel in an aircraft fuel tank by Charles S Stone ( Book )
1 edition published in 1945 in English and held by 1 WorldCat member library worldwide
An investigation was conducted to determine the feasibility of using the change in the specific gravity of fuels in aircraft fuel tanks to measure fuel-vaporization loss. The relation of specific gravity to fuel loss for each of the six fuels tested was determined by fuel-distillation tests and for three of the same fuels, by simulated-flight tests. The increase in specific gravity was found to be a linear function of fuel-vaporization loss up to the 40-percent fuel-loss point. An equation based on the specific gravity of the fuel was found to be accurate to within plus or minus 0.32-percent fuel loss. This method can be used for determining the fuel-vaporization loss from fuel tanks in combat and transport aircraft where other methods of measurement are not practicable
Fuel consumption corrected for cooling drag of an air-cooled radial aircraft engine at low fuel-air rations and with variable spark advance by J. Elmo Farmer ( Book )
1 edition published in 1945 in English and held by 1 WorldCat member library worldwide
Reliability and power capacity are the only factors in the operation of aircraft engines that are of greater importance than fuel economy. A reduction in engine specific fuel consumption will result in either increased range or increased useful load. If minimum fuel consumption at any power output is to be achieved, the most favorable conditions of engine operation must be selected

Addition of heat to a compressible fluid in motion by Bruce L Hicks ( Book )
1 edition published in 1945 in English and held by 1 WorldCat member library worldwide
The nature of nonadiabatic, frictionless, steady flow of a compressible fluid in a pipe of constant cross section is summarized. The flow conditions can most conveniently be described in terms of the local Mach number M. It was found that steady flow cannot occur when heat is being added to the fluid at a point where the velocity equals the local velocity of sound (M = 1), and that the maximum temperature of the fluid occurs at M = 1/square root of gamma where gamma is the ratio of specific heats. These results are illustrated by application of high-speed flow through combustion chambers
Operating stresses in aircraft-engine crankshafts and connecting rods. 1 - Slip-ring and brush combinations for dynamic-strain measurements by Francis J Dutee ( Book )
1 edition published in 1945 in English and held by 1 WorldCat member library worldwide
Tests were conducted to develop a slip-ring and brush system that will perform satisfactorily in aircraft-engine, dynamic-strain-measuring applications where resistance-wire strain gages are the means of measuring the stain and to correlate the data obtained from tests in order to provide a basis for predicting the performance of similar slip-ring and brush systems operating under conditions similar to those imposed by these tests

1 edition published in 1945 in English and held by 1 WorldCat member library worldwide
The analysis of the test data from these two engines led to the establishment of a relation of variables upon which the design of automatic metering controls can be based. The results of this analysis also substantiate the conclusions presented in a similar published report
Analysis and correlation of data obtained by six laboratories on fuel-vapor loss from fuel tanks during simulated flight by Charles S Stone ( Book )
1 edition published in 1944 in English and held by 1 WorldCat member library worldwide
Data on fuel-vapor loss from fuel tanks during simulated flight obtained by six laboratories were analyzed to show the effects of individual variables such as altitude, initial fuel temperature, rate of climb, booster-pump agitation, fuel depth, fuel-surface area, types of fuel, and vent-line pressure drop on fuel-vapor loss. From this analysis, a number of conclusions were reached
