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 ]
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 ...
However, the US Congress in 2014 advocated a new US rocket engine program to field a new engine by 2022. [ 10 ] In June 2014, Aerojet Rocketdyne proposed that the federal government "fund an all-new, U.S.-sourced rocket propulsion system", the 2,200-kilonewton-class (500,000 lbf) thrust kerosene/ LOX AR1 rocket engine .
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".

It produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. [1] Together these parts comprise the control system for a jet engine, responsible for delivering the correct amount of fuel and maintaining engine safety.
