and even hybrid rocket engines are becoming passé. We’ve never seen a liquid-fuel rocket build before, so that’s what this roundup evolved into. First up is [Robert Watzlavick], who has been ...

While we’re reluctant to say it for fear of being misinterpreted, the new liquid fuel rocket engine being built by Copenhagen Suborbitals is one of the most impressive, daring, and nearly the ...

According to the Blue Origin website, the engines of the Blue Origin New Glenn reusable rocket were made in Kent, Wash. and ...

Description: Project BLERP aims to design and construct a reusable liquid rocket engine and launch stand that can be re-used and studied by future ... The design will incorporate a pressurized fill ...

The focus is on investigating the behavior of an entire liquid-fueled rocket cycle and its individual components in a representative ... while optimising the thrust or fuel consumption of the engine.

"Preliminary indication is that we had an oxygen/fuel leak in the cavity above the ship engine firewall that was large enough ...

The focus is on investigating the behavior of a complete liquid rocket cycle and its individual components in a representative test environment. Part of the project is the design, production and ...

Elon Musk’s SpaceX suspects a fire is to blame for his 400-foot-tall Starship breaking apart in space after launching from Texas — sending trails of flaming debris raining down near ...

Most liquid-fuel rocket engines require a secondary combustion chamber to which some fuel is diverted; the exhaust gas is shot through a turbine to pump fuel and oxygen into the main chamber.

The SpaceX Falcon 9's Merlin engines use rocket-grade kerosene (RP-1) fuel with liquid oxygen as the oxidizer. NASA's Space Launch System is based on liquid hydrogen fuel and liquid oxygen oxidizer.

Liquid oxygen boils at -183°C (–297°F), and requires specialized fuel storage and other equipment, Lee said. That may account for why North Korea conducted multiple static rocket tests late ...

Using less fuel makes it easier to prepare these ... RDRE system that will match the performance of traditional liquid rocket engines. If upcoming tests prove successful, they could revolutionize ...
