Flometrics
Flometrics is a San Diego based engineering company that was formed in the garage of Dr. Steve Harrington in 1990. The engineers specialize in thermodynamics and fluid dynamics, but were widely publicized for launching a rocket running on a biofuel "developed by the EERC under a DARPA contact." Bio-fuel Rocket In July 2009 the Flometrics team launched a Rocketdyne LR-101 engine running on bio-fuel developed by the Energy and Environmental Research Center. The fuel ended up pushing the rocket close to Mach 1 and sending it 20,000 ft into the sky. The fuel was developed with the military grade JP-8 fuel criteria in mind. The rocket was originally designed for use on Mythbusters and for RP-1 kerosene based rocket fuel. "This is a unique opportunity for the EERC's renewable fuel," said EERC Director Gerald Groenewold. "Our fuel is already providing a pathway to energy security to the U.S. military and now is becoming an option for ground-to-air missiles and even space flight." Ap ...

Pistonless Pump
A pistonless pump is a type of pump designed to move fluids without any moving parts other than three chamber valves. The pump contains a chamber which has a valved inlet from the fluid to be pumped, a valved outlet – both of these at the bottom of the pump, and a pressurant inlet at the top of the pump. A pressurant is used, such as steam or pressurized helium, to drive the fluid through the pump. Introduction NASA have developed a low-cost rocket-fuel pump which has comparable performance to a turbopump at 80–90% lower cost. Perhaps the most difficult barrier to entry in the liquid rocket business is the turbopump. A turbopump design requires a large engineering effort and is expensive to manufacture and test. Starting a turbopump-fed rocket engine is a complex process, requiring a careful synchronisation of many valves and subsystems. In fact, Beal aerospace tried to avoid the issue entirely by building a huge pressure feed booster. Their booster never flew, but the engine ...

Crew Exploration Vehicle
The Crew Exploration Vehicle (CEV) was a component of the U.S. NASA Vision for Space Exploration plan. A competition was held to design a spacecraft that could carry humans to the destinations envisioned by the plan. The winning design was the Orion spacecraft. Although it was originally conceived during the Space Exploration Initiative during the 90s, official planning for the vehicle began in 2004, with the final Request For Proposal issued on March 1, 2005, to begin a design competition for the vehicle. For the later design and construction phases, see Orion (spacecraft). The Orion CEV became part of NASA's Constellation Program to send human explorers back to the Moon, and then onward to Mars and other destinations in the Solar System. After Constellation was cancelled, it was envisioned for emergency evacuation of the International Space Station, then retained for revived Solar System exploration plans. Competition The concept for the vehicle was officially announce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Popular Science
''Popular Science'' (also known as ''PopSci'') is an American digital magazine carrying popular science content, which refers to articles for the general reader on science and technology subjects. ''Popular Science'' has won over 58 awards, including the American Society of Magazine Editors awards for its journalistic excellence in 2003 (for General Excellence), 2004 (for Best Magazine Section), and 2019 (for Single-Topic Issue). With roots beginning in 1872, ''Popular Science'' has been translated into over 30 languages and is distributed to at least 45 countries. Early history ''The Popular Science Monthly'', as the publication was originally called, was founded in May 1872 by Edward L. Youmans to disseminate scientific knowledge to the educated layman. Youmans had previously worked as an editor for the weekly ''Appleton's Journal'' and persuaded them to publish his new journal. Early issues were mostly reprints of English periodicals. The journal became an outlet for writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrophile
A hydrophile is a molecule or other molecular entity that is attracted to water molecules and tends to be dissolved by water.Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon'' Oxford: Clarendon Press. In contrast, hydrophobes are not attracted to water and may seem to be repelled by it. Hygroscopics ''are'' attracted to water, but are not dissolved by water. Molecules A hydrophilic molecule or portion of a molecule is one whose interactions with water and other polar substances are more thermodynamically favorable than their interactions with oil or other hydrophobic solvents. They are typically charge-polarized and capable of hydrogen bonding. This makes these molecules soluble not only in water but also in other polar solvents. Hydrophilic molecules (and portions of molecules) can be contrasted with hydrophobic molecules (and portions of molecules). In some cases, both hydrophilic and hydrophobic properties occur in a single molecule. An example of these amphiph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
YouTube
YouTube is a global online video platform, online video sharing and social media, social media platform headquartered in San Bruno, California. It was launched on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim. It is owned by Google, and is the List of most visited websites, second most visited website, after Google Search.

RP-1
RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (LH2), but is cheaper, is stable at room temperature, and presents a lower explosion hazard. RP-1 is far denser than LH2, giving it a higher energy density (though its specific energy is lower). RP-1 also has a fraction of the toxicity and carcinogenic hazards of hydrazine, another room-temperature liquid fuel. Usage and history RP-1 is a fuel in the first-stage boosters of the Electron, Soyuz, Zenit, Delta I-III, Atlas, Falcon, Antares, and Tronador II rockets. It also powered the first stages of the Energia, Titan I, Saturn I and IB, and Saturn V. The Indian Space Research Organization (ISRO) is also developing an RP-1 fueled engine for its future rockets. Development During and immediately after World War II, alcohols (primarily ethanol, occasionally metha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mythbusters
''MythBusters'' is a science entertainment television program, developed by Peter Rees and produced by Australia's Beyond Television Productions. The series premiered on the Discovery Channel on January 23, 2003. It was broadcast internationally by many television networks and other Discovery channels worldwide. The show's original hosts, special effects experts Adam Savage and Jamie Hyneman, used elements of the scientific method to test the validity of rumors, myths, movie scenes, adages, Internet videos, and news stories. The show was one of the most popular on Discovery Channel, being preceded only by ''How It's Made'' and ''Daily Planet'', both in Canada. Filmed in San Francisco and edited in Artarmon, New South Wales, ''MythBusters'' aired 282 total episodes before its cancellation at the end of the 2016 season in March. Planning and some experimentation took place at Hyneman's workshops in San Francisco; experiments requiring more space or special accommodations we ...

JP-8
JP-8, or JP8 (for "Jet Propellant 8") is a jet fuel, specified and used widely by the US military. It is specified by MIL-DTL-83133 and British Defence Standard 91-87, and similar to commercial aviation's Jet A-1, but with the addition of corrosion inhibitor and anti-icing additives. A kerosene-based fuel, JP-8 is projected to remain in use at least until 2025. It was first introduced at NATO bases in 1978. Its NATO code is F-34''. Usage It was specified in 1990 by the U.S. government as a replacement for government diesel fueled vehicles. The U.S. Air Force replaced JP-4 with JP-8 completely by the end of 1995, to use a less flammable, less hazardous fuel for better safety and combat survivability. The U.S. Navy uses a similar formula, JP-5. JP-5 has an even higher flash point of > 140 °F (60 °C), but also a higher cost, though the U.S. Navy Seabees still use JP-8 in their construction and tactical equipment. In addition to its use for powering aircraft, JP-8 is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
