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 ]
