Rutherford is a liquid-propellant rocket engine designed by aerospace company Rocket Lab [8] and manufactured in Long Beach, California. [9] The engine is used on the company's own rocket, Electron. It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle.
Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. [17] Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable , Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. [ 18 ]
The Rutherford engine uses pumps driven by battery-powered electric motors rather than a gas generator, expander, or preburner. [107] The engine is fabricated largely by 3D printing , using electron beam melting , [ 108 ] whereby layers of metal powder are melted in a high vacuum by an electron beam. [ 109 ]
BitTorrent sites may operate a BitTorrent tracker and are often referred to as such. Operating a tracker should not be confused with hosting content. A directory allows users to browse the content available on a website based on various categories. A directory is also a site where users can find other websites.

The Curie engine, named after Polish scientist Marie Skłodowska–Curie, is a small liquid-propellant rocket engine designed to release "small satellites from the constricting parameters of primary payload orbits and enables them to fully reach their potential, including faster deployment of small satellite constellations and better positioning for Earth imaging". [3]
Archimedes is presented as a highly reusable liquid-propellant engine using methane and liquid oxygen in an oxidizer-rich staged combustion cycle. [1] [2] There are both sea-level and vacuum variants. The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas ...
Torrent was acquired by Ascential Software in late 2001 [2] for about $46 million; Orchestrate became part of Ascential's DataStage data integration system, which became part of IBM's Information Server product when Ascential was acquired by IBM in mid-2005. Torrent technology became the Parallel Engine in the Information Server architecture.
