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.
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 United States Navy occupational rating of data systems technician (abbreviated as DS) was a designation given by the Bureau of Naval Personnel to enlisted members who satisfactorily complete initial data systems technician "A" school training. The primary training location for the DS rating was Combat System Technical Schools Command (CSTSC ...
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]

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 ...
The investigation revealed that the second stage igniter fault induced an interference with the engine controller that caused the data signal corruption for the thrust vector control (TVC) system, straying the vehicle off course.
