3D Printed liquid-fuel rocket motor - Aerospace Manufacturing and Design (press release)

Finding a new way to deliver liquid fuel through 3D printing is a significant advance in rocket motor technology. Fuller says 3D-printed helical shapes enable the liquid or gas oxidizer to interact with the solid fuel more effectively, dramatically ...

85 years ago: The USSR launched its first rocket using liquid propellant - RussianSpaceWeb.com

On Aug. 17, 1933, the group of Soviet engineers from the GIRD rocket research organization, successfully fired the first Soviet rocket burning liquid oxygen. The GIRD-09 experimental vehicle flew for 18 seconds and reached around 400 meters in altitude ...

Virgin Galactic's Rocket Man - The New Yorker

After considering safety, cost, and the touristic goal of allowing passengers to view Earth while weightless, Virgin Galactic settled on a hybrid-fuel rocket that combined solid fuel with a liquid oxidizer. This configuration allows the pilot, at any ...

Pencils down: OmegA awaits final grade on EELV - The Space Review

All of OmegA's solid rocket motors will make use of the latest in solid propellant technology. Whereas liquid propellant stages (like OmegA's upper stage) require the skills of a rocket plumber, solids need a rocket baker. The go-to solid propellant ...

Private firms race to build carrier rockets - CGTN (press release)

His company has also begun to design the Hyperbola-3, a larger rocket with nine 15-ton-thrust, liquid-propellant engines, and plans to launch it as early as 2020, Xie said. In late June, i-Space announced it has received an investment of 600 million ...

ISRO Conducts Successful Ground Test of Vikas High Thrust Rocket Engine - Beebom (blog)

The Indian Space Research Organization (ISRO) has successfully conducted the first ground test of the improved Vikas Engine which is now capable of generating higher thrust, thanks to multiple upgrades by the team at the Indian space agency. The test ...

Europe will fire its record-setting big solid rocket motor this week - The Verge

Solid rocket motors like the P120C are a relatively rare breed these days. Most major rockets rely on engines that run on cold liquid propellants, like cryogenic oxygen and hydrogen. These engines operate by feeding two types of liquids — a fuel and ...

Chinese Space Company Planning Launch of Largest Privately Owned Liquid Rocket - Sputnik International

"The medium-sized liquid launch vehicle is a shortage [in the] rocket launching market and an environmentally friendly, cost-effective, high-thrust rocket engine determines the competitiveness of the launch vehicle in the market," Zhang recently told ...

Saturn V: The birth of the moon rocket - New Atlas

If that isn't enough, it's also not only the largest liquid-fueled rocket, but the largest flying machine ever built. Its F-1 first stage engine is the most powerful to go into service. The construction of the 13 Saturn Vs that flew, and their 19 ...

Russia tests laser ignition for oxygen-hydrogen rocket engine for first time - TASS

"Assimilating this technology already for oxygen-hydrogen, we are making a big step towards creating reliable multiple-ignition liquid propellant rocket engines that will find their application in promising domestic reusable space rocket systems," the ...

It Takes a Village to Raze a Test Stand - ArmsControlWonk.com

In post-summit comments, the President indicated that the DPRK had agreed to destroy a “missile engine testing site,” which the U.S. identified “because of the heat.” This has brought up the question of which site does he mean? Dave Schmerler did an ...

A rocket that devours itself - The Economist

Like firework rockets (themselves solid-fuelled), once the metaphorical blue touchpaper has been lit, the fuel burns as it will. Liquid-fuelled rockets are preferred as satellite launchers because their thrust can be tuned by changing the flow of ...

A liquid-propellant rocket or liquid rocket is a rocket engine that uses liquid propellants. Liquids are desirable because their reasonably high density allows the volume of the propellant tanks to be relatively low, and it is possible to use lightweight centrifugal turbopumps to pump the propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks, resulting in a high mass ratio for the rocket.

A liquid-propellant rocket or liquid rocket is a rocket engine that uses liquid propellants. Liquids are desirable because their reasonably high density allows the volume of the propellant tanks to be relatively low, and it is possible to use lightweight centrifugal turbopumps to pump the propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks, resulting in a high mass ratio for the rocket.

An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a lower mass ratio, but are usually more reliable. and are therefore used widely in satellites for orbit maintenance.

Liquid rockets can be monopropellant rockets using a single type of propellant, bipropellant rockets using two types of propellant, or more exotic tripropellant rockets using three types of propellant.

Some designs are throttleable for variable thrust operation and some may be restarted after a previous in-space shutdown. Liquid propellants are also used in hybrid rockets, in which a liquid oxidizer is generally combined with a solid fuel.
