The Path of Carbon in Photosynthesis. XIV.

Description: It seems hardly necessary to repeat to an audience of this kind the importance of the process known as photosynthesis in the interaction and the interdependence of organisms and in the very existence of life as we know it. This process by which green plants are able to capture electromagnetic energy in the form of sunlight and transform it into stored chemical energy in the form of a wide variety of reduced (relative to carbon dioxide) carbon compounds provides the only major source of energy f… more

Preliminary investigation of the pressure fluctuations in the wakes of two-dimensional wings at low angles of attack

Description: Report presenting a measurement of the magnitudes of pressure fluctuations in the turbulent wakes of restrained two-dimensional airfoils at transonic speeds. Measurements indicated that the total-pressure fluctuations occurred only within the wake. Results regarding the magnitude of pressure oscillation in the wake, effect stream-angle fluctuations in the wake, and frequencies of pressure oscillation on the wing and in the wake are provided.

Preliminary evaluation of the air and fuel specific-impulse characteristics of several potential ram-jet fuels 1: octene-1, aluminum, and aluminum - octene-1 slurries

Description: Report presenting a preliminary analytical evaluation of the air and fuel specific-impulse characteristics of octene-1, aluminum, and aluminum-octene-1 slurries. The adiabatic combustion flame temperature, combustion equilibrium-gas composition, air specific impulse, and fuel-weight specific impulse are presented for each fuel. Aluminum-octene-1 slurries were found to offer a means of increasing the limited air specific impulse values available with octene-1 or hydrocarbon-type fuels.

Effect of Fuel Volatility on Performance of Tail-Pipe Burner

Description: Fuels having Reid vapor pressures of 6.3 and 1.0 pounds per square inch were investigated in a tail-pipe burner on an axial-flow-type turbojet engine at a simulated flight Mach number of 0.6 and altitudes from 20,000 to 45,000 feet. With the burner configuration used in this investigation, having a mixing length of only 8 inches between the fuel manifold and the flame holder, the low-vapor-pressure fuel gave lower combustion efficiency at a given tail-pipe fuel-air ratio. Because the exhaust-no… more

Design and performance of an experimental axial-discharge mixed-flow compressor 3: over-all performance of impeller and supersonic-diffuser combination

Description: Report presenting an investigation of an axial-discharge impeller in combination with a 16-vaned supersonic diffuser cascade over a range of flow conditions at equivalent tip speeds varying from 800 to 1600 feet per second. Results regarding the overall performance of the combination, starting of diffuser cascade, use of flow bleedoff to aid starting, radial distribution of flow angle, flow characteristics within diffuser, and efficiency of diffuser cascade are provided.

The Use of Suction to Prevent Shock-Induced Separation in a Nozzle

Description: "An investigation was made of the use of suction to prevent shock-induced flow separation in a nozzle formed by a 7.5-percent-thick bump on a wall of a channel. Various transverse and longitudinal suction-slot arrangements and suction through porous surfaces were tested. All these devices were effective in preventing separation, and certain suction-slot arrangements reduced the total power loss, including the power lost in the suction process" (p. 1).

Investigation of the liquid fluorine-liquid diborane propellant combination in a 100-pound-thrust rocket engine

Description: The experimental performance of liquid fluorine and liquid diborane was investigated in a 100-pound-thrust engine at a combustion pressure of 300 pounds per square inch absolute. Methods of handling and transporting liquid fluorine were developed. It was extremely difficult to obtain satisfactory operation because of the high flame speed and high combustion chamber temperatures. The maximum performance obtained was 280 pound seconds per pound, 88 percent of the theoretical maximum. The theoreti… more

Spectrum of turbulence in a contracting stream

Description: The spectrum concept is employed to study the selective effect of a stream contraction on the longitudinal and lateral turbulent velocity fluctuations of the stream. By a consideration of the effect of the stream contraction on a single plane sinusoidal disturbance wave, mathematically not dissimilar to a triply periodic disturbance treated by G. I. Taylor, the effect on the spectrum tensor of the turbulence and hence on the correlation tensor is determined.
