5 Scuba Air Compressors [For Filling Tanks & On Boat]
Saved by uncleflo on June 13th, 2022.
Once diving becomes a serious hobby, you might be interested in buying your own compressor for filling your tanks. There is nothing wrong with dive shops, but there’s nothing like being able to fill up your tank wherever you are. Since the air in your tank is a matter of life or death, the air compressor for your scuba tank needs to provide you with clean pressurized air. When you choose a scuba air tank compressor, it needs to be specifically made for diving. Unless the compressor delivers clean breathing air at high pressures, you risk injury or death when you dive. This guide will help you understand how a compressor works, what makes a scuba air compressor different from a normal one, and what to look for when buying one. Many companies build compressors, but only a few manufacture breathing air compressors for scuba diving. We recommend the following

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.

How a Sail Gives Lift
Saved by uncleflo on April 10th, 2021.
How many times have you heard that a sail gives lift to drive a boat because, "the air travels faster on the lee side for it has farther to go than it does on the windward side. So the pressures are different and you get lift." Well, that is wrong! Even a perfectly flat thin airfoil, with the same distance on both sides, has lift when it is at an angle to the wind.

Enjoy your sailboat to the fullest, with a silent drive and truly fresh air. This system is recommended for boats up to 12,000 pounds displacement. All our systems have reverse on-the-fly and contactor disable features. "Brushless" means that the motor does not have brushes that will wear out over time, nor will it be a dangerous source of ignition for on-board gas appliances. Larger boats may require a higher power AC or brushless motor. In the U.S. and Canada, brushed motors are only legal for marine use if onboard appliances and accessories use kerosene or diesel (not propane or gasoline) due to the potential for internal motor arcing.

Filming in London - Aerial filming
Saved by uncleflo on December 20th, 2018.
There are various permissions and considerations in order to operate a drone for aerial filming in London. Drones may also be referred to as Unmanned Aerial Vehicles (UAV), Small Unmanned Aircraft (SUA) or Unmanned Aerial Systems (UAS). All commercial drone operators must be in possession of a CAA permission document. Any drone flight in an urban area or near large crowds of people, whether for private or commercial purposes, will require the same document. The CAA grants permission for multi-rotor and fixed-wing type, and will only grant permission for drones that do not exceed 20kg.Productions using drones for filming purposes must ensure they are familiar with aircraft legislation and procedures that relate to aerial filming in London. Due to the nature of the local airspace and the density of population there are some important restrictions on the operation of aircraft in and around the capital.

List of Mayday episodes
Saved by uncleflo on October 23rd, 2018.
Mayday, known as Air Crash Investigation(s) outside of the United States and Canada and also known as Air Emergency or Air Disasters (Smithsonian Channel) in the United States, is a Canadian documentary television series produced by Cineflix that recounts air crashes, near-crashes, fires, hijackings, bombings, and other mainly flight-related disasters and crises. It reveals the events that led to each crisis or disaster, their causes as determined by the official investigating body or bodies, and the measures they recommended to prevent a similar incident from happening again. The programs use re-enactments, interviews, eyewitness testimony, computer-generated imagery, cockpit voice recordings, and official reports to reconstruct the sequences of events. As of 10 September 2018, 170 episodes of Mayday have aired. This includes five Science of Disaster specials, each examining multiple crashes with similar causes. For broadcasters that do not use the series name Mayday, three Season 3 episodes were labeled as Crash Scene Investigation spin-offs, examining marine or rail disasters.

Air-augmented rocket - Wikipedia, the free encyclopedia
Saved by uncleflo on September 2nd, 2014.
Air-augmented rockets (also known as rocket-ejector, ramrocket, ducted rocket, integral rocket/ramjets, or ejector ramjets) use the supersonic exhaust of some kind of rocket engine to further compress air collected by ram effect during flight to use as additional working mass, leading to greater effective thrust for any given amount of fuel than either the rocket or a ramjet alone. It represents a hybrid class of rocket/ramjet engines, similar to a ramjet, but able to give useful thrust from zero speed, and is also able in some cases to operate outside the atmosphere, with fuel efficiency not worse than both a comparable ramjet or rocket at every point.

Buzz Aldrin
Saved by uncleflo on September 2nd, 2014.
Selected by NASA in 1963 into the third group of astronauts, Aldrin was the first with a doctorate and became known as “Dr. Rendezvous.” The docking and rendezvous techniques he devised for spacecraft in Earth and lunar orbit became critical to the success of the Gemini and Apollo programs, and are still used today. He also pioneered underwater training techniques, as a substitute for zero gravity flights, to simulate spacewalking. In 1966 on the Gemini 12 orbital mission, Buzz performed the world’s first successful spacewalk, overcoming prior difficulties experienced by Americans and Russians during extra-vehicular activity (EVA), and setting a new EVA record of 5 ½ hours. On July 20, 1969, Buzz and Neil Armstrong made their historic Apollo 11 moonwalk, becoming the first two humans to set foot on another world. They spent 21 hours on the lunar surface and returned with 46 pounds of moon rocks.

The SR-71 Blackbird is powered by two Pratt & Whitney J-58 turbo-ramjets, each developing 32,500 pounds of thrust with afterburning. The critical problems concerning supersonic flight with air breathing engines are concentrated in the air inlet area. The circular air intakes of the SR-71 contain a center body tipped with a conical spike. The spike is movable, forward for takeoff and climb to 30,000 feet after which, as speed builds up, it moves rearward, controlling the amount of air entering the engine. As it does so, Air Inlet Bypass Doors in the side of the nacelle close to establish the correct flow of air through the engine, holding the supersonic shock wave in it's critical position within the inlet. The engine itself operates at subsonic speed.

FoilSim Download
Saved by uncleflo on June 3rd, 2014.
FoilSim - Student was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. FoilSim is interactive simulation software that determines the airflow around various shapes of airfoils. The Airfoil View Panel (shown below) is a simulated view of a wing being tested in a wind tunnel with air moving past it from left to right. Students change the position and shape of the wing by moving slider controls that vary the parameters of airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area. The software displays plots of pressure or airspeed above and below the airfoil surface. A probe monitors air conditions (speed and pressure) at a particular point on or close to the surface of the airfoil. The software calculates the lift of the airfoils, allowing students to learn the factors that influence lift. The software includes a stall model for the airfoil and a model of the Martian atmosphere for lift comparisons. The latest version (FoilSim III - Version 1.4b) performs a table look-up of experimental data to determine the drag of the foil. A technical paper describing the details of the mathematical method used in FoilSim is also available.
