graphite solution - high powered rockets and future

Fangruida

The father of modern non-traditional chemical-fuel dual-engine high-speed heavy-load rockets (nuclear-powered high-polymer composite rocket technology integration) -Fangruida (Alvis) Fang Ruida (1950-), a world famous scientist, inventor, physicist, philosopher, astronomer, cosmologist and

Hybrid

One problem in designing large hybrid orbital rockets is that turbopumps become necessary to achieve high flow rates and pressurization of the oxidizer. This turbopump must be powered by something. In a traditional liquid-propellant rocket, the turbopump uses the same fuel and oxidizer as the rocket, since they are both liquid and can be fed to the pre-burner.

Space Future

Space Future is for everyone who'd like to visit space. Features include the archive of space tourism work, information on vehicles, tourism and power plus mailing lists and the Space Future Journal. SPACESHIPONE WHITE KNIGHT Winner of the $10m Ansari X-Prize, this suborbital passenger-carrying spaceplane was designed by Burt Rutan 's Scaled Composites, famous for graphite composites, and

The Most Important Maglev Applications

The name maglev is derived from magnetic levitation. Magnetic levitation is a highly advanced technology. It has various uses. The common point in all applications is the lack of contact and thus no wear and friction. This increases efficiency, reduces maintenance

Nuclear Powered Space Missions

Third, multiple layers of protective materials, including iridium capsules and high-strength graphite blocks, are used to protect the fuel and prevent its accidental release. Iridium is a metal that has a very high melting point and is strong, corrosion resistant and chemically compatible with plutonium dioxide.

Graphene Supercapacitors

While graphene-based supercapacitors are currently a viable solution in the future, technology needs to be developed to make this into a reality. But rest assured, many companies around the world are already trialling products using this technology and creating new ways to help subsidise the use of fossil-fuels and toxic chemicals in our ever-demanding strive for energy.

Power Plant

The future carrier CVN(X) will be nuclear powered and have a steam plant but will also have increased electrical generation (104MVA) to support launching planes using electrical power. Neither DD(X) nor CVN(X) is designed to deliver power outside the hull, but it would be easier to export it as electrical current than as steam.

Hot Topic: Carbon, Graphite, and Graphene

2021/3/15Talking about carbon, one automatically thinks of carbon nanotubes and fullerenes. But there is much more to this broad subject area. Advances in graphene research, templating methods, and the emergence of nanodiamonds make this field a rich area of research.

How Ion harvesting Works On Earth

Trillions of naturally renewable electrically charged ions are continuously produced in the atmosphere, around the clock, day night, powered by the Sun's enormous energy. A revolutionary breakthrough in nanomaterial research demonstrates that exposing a special type of ultra-lightweight carbon nanomaterial to atmospheric ions harvests high-voltage electricity, day, night, and during storms.

How to Make Sugar Rockets (with Pictures)

2021/3/28How to Make Sugar Rockets. A sugar rocket is a simple home project that uses potassium nitrate (KNO3) and powdered sugar as fuel. While it's easy to make a sugar rocket, it's also very dangerous, so use caution throughout your project. To

Review Geek – Make Gadgets Fun Again

But Samson is offering an affordable, low-effort entry point to the world of high-quality audio with its $200 Q9U broadcast mic. With excellent noise rejection and options for USB-C or XLR connections, the Q9U is one of the best entry-level mics available today.

Nearlight Starships

2021/4/30Over dinner Bussard told me he started working on nuclear propulsion at Los Alamos in 1955, and that he and R. DeLauer wrote the first monograph on atomic powered rockets in 1959 [1]. He also said he had been looking at work at Lawrence Radiation Laboratory in 1959.

PNNL: Who Killed the Graphite Anode?

Graphite anodes are used in nearly all Li-ion batteries, but recent research has sought to capitalize on a better anode solution—silicon. With a theoretical capacity of more than 10 times that of graphite, silicon anodes can at least double the capacity of graphite-anode batteries.

The Future Battlespace

High-Speed Weapons Operating at extreme speeds and high altitudes, hypersonic weapons are hard to stop. Raytheon is a leader in the development of hypersonic solutions for the U.S. Department of Defense, having been awarded several priority contracts in this most demanding of science and technology fields.

DC ARC FURNACES – PAST, PRESENT, AND FUTURE

Around about the same time, also in the 1970s, ASEA in Sweden developed high-power thyristor rectifiers. Sven-Einar Stenkvist investigated the conversion of AC open arc furnaces to DC, principally for steelmaking. He implemented the idea of using a graphite

Step Aside, Rockets

Ion engines use electric power to create charged particles of the fuel, usually the gas xenon, and accelerate them to extremely high velocities. The exhaust velocity of conventional rockets is limited by the chemical energy stored in the fuel's molecular bonds, which limits the thrust to about 5km/s.

Air

A SABRE-powered launch vehicle will therefore have lower mass for a given payload than a conventional rocket vehicle. This mass benefit can be traded for systems that will enable reusability and aircraft-like traits, such as wings, undercarriage and thermal-protection systems – all the features needed to fly the same vehicle over and over again, achieving hundreds of launches.

The negative electrode, or anode, is made of graphite—a form of pure carbon. The electrolyte is a non-aqueous solution of lithium salt. A permeable membrane, called the separator, plays a critical role between the positive and negative electrodes.
