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 J-2S rocket engine, a cancelled engine developed by NASA, used the combustion tap-off cycle and was first successfully tested in 1969. [2] By 2013, Blue Origin, with their New Shepard launch vehicle, had successfully flight-tested the BE-3 engine using a tap-off cycle. According to Blue Origin, the cycle is particularly suited to human ...
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 ]
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 generator was that they could not get the performance they needed through all the throttle points that a reusable rocket needs, without pushing the turbine temperature and other factors beyond their ...
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]
Electrical pumps had been used in the secondary propulsion system of the Agena upper stage vehicle. [ 1 ] As of December 2020, the only rocket engines to use electric propellant pump systems are the Rutherford engine, [ 2 ] ten of which power the Electron rocket, [ 2 ] and the Delphin engine, five of which power the first stage of Astra Space ...
