Oxygen concentrator | ScubaBoard
Saved by uncleflo on January 13th, 2022.
Forum topic about creating an oxygen concentrator to fill up oxygen bottles. A user asks: Is any one here is using or has used an oxygen concentrator. I do know you cannot get 100% pure oxygen. Basically it is a PSA oxygen concentrator that also has a compressor mounted to it that pumps direct to scuba tanks. It will also provide continuous flow for blending, but a concentrator that small doesn't put out enough for a big compressor. Several manufacturers have boosters designed for this application though. Invacare homefill, Rix microboost *yes this was actually designed around PSA oxygen concentrators*, Philips Ultrafill *only one that will go to 3000psi*, and a few others. I use one and fill 2200 psi O2 bottles to do PP blending nitrox. It's a invocare homefill set up. Makes perhaps 200+ cuft a day of 96% O2. 2 days to fill a standard 5' tall O2 bottle used for standard acetalyne rigs. These systems can be hard to get because they need a perscription to get one. but some will sell for hobby use. (glass works etc.) I think you can still get the concentrator and compuressor for about 1000 $ and then there is an adaptor hose that is needed to connect to fill tanks that may be 100 $ unless you hae one of hte designed carry around tanks to get the part from. There are other solutions of course. Keep the unit indoors or somewhere where it is dry and low humidity and the concentrator will last a long time. I will post pics of what i have if any one want s to see them. PM me.

Basic of Space Flight: Rocket Propellants
Saved by uncleflo on September 2nd, 2014.
Propellant is the chemical mixture burned to produce thrust in rockets and consists of a fuel and an oxidizer. A fuel is a substance that burns when combined with oxygen producing gas for propulsion. An oxidizer is an agent that releases oxygen for combination with a fuel. The ratio of oxidizer to fuel is called the mixture ratio. Propellants are classified according to their state - liquid, solid, or hybrid. The gauge for rating the efficiency of rocket propellants is specific impulse, stated in seconds. Specific impulse indicates how many pounds (or kilograms) of thrust are obtained by the consumption of one pound (or kilogram) of propellant in one second. Specific impulse is characteristic of the type of propellant, however, its exact value will vary to some extent with the operating conditions and design of the rocket engine.

Gnom was a unique design which represented the most advanced work ever undertaken on an air-augmented missile capable of intercontinental ranges or orbital flight. Although cancelled in 1965 before flight tests could begin, Gnom was the closest the world aerospace engineering community ever came to fielding an orbital-capable launcher of less than half of the mass of conventional designs.
