Spray properties of unlike impinging streams of nonreacting fluids for design application to liquid propellant rocket engine injector
Spray-on process constructs molds used in forming sections of thermal insulation blankets. The process simplifies the fabrication of blankets by eliminating much of the equipment formerly required and decreasing the time involved.
Multilayer rocket nozzles formed by plasma spraying have good thermal shock resistance and can be reheated in an oxidizing environment without loss of coating adherence. Suggested application of this process are for the production of refractory components, which can be formed as surfaces of revolution.
Easily applied EKG electrodes monitor the heart signals of human subjects engaged in various physical exercises. The electrodes are formed from an air drying, electrically conductive cement mixture that can be applied to the skin by means of a modified commercially available spray gun.
Casting, powder metallurgy, electroforming, metal spraying, and chemical vapor deposition techniques for producing nickel and nickel-alloy shapes
Analysis based on one-dimensional shock wave theory to study maximum velocity of spray emanating from rear surface of thin meteoroid bumper
Metal flame spray coating prevents EMF measurement error in sheathed instrumentation cables which are externally attached to cylinders which were cooled on the inside, but exposed to gamma radiation on the outside. The coating provides a thermoconductive path for radiation induced high temperatures within the cables.
Heat sinks in electronic packaging can be flame sprayed with dielectric coatings of alumina or beryllia and finished off with an organic sealer to provide high heat and electrical resistivity.
Fluorescent photography of droplets in spray using Q-switched laser as light source
Q-switched laser use as light source for photographing droplets in spray containing fluorescent dye excited by second harmonic of ruby light
Logarithmic normal and Chi-square distribution functions evaluated for determining drop size distribution in liquid sprays
Pulsed ruby laser holograms of reacting liquid propellant sprays
Experimental results of drop size effects in spray detonations of liquid diethylcyclohexane
Holograms and laser-illuminated photography of reacting sprays in liquid propellant rocket engines
Improved agar spray technique for sampling surface microorganism
Structural changes on reheating plasma sprayed alumina free standing shapes, noting polymorphic transformations effect on porosity and pore size distribution
Monochromatic laser emission transformed by a fluorescent process into droplet emission over a wavelength band provides high light intensities for obtaining adequate time resolution to stop droplet motion in photographic spray studies. Experiments showed that the Q-switched laser-optical harmonic generator combination produced sharp, well-exposed droplet images.
Metallic coating directly sprayed on electronic modules provides simple and reliable lightweight protection against radio frequency interference. A plasma arc may be used. Aluminum and copper are the most effective metals.
