Engineers prepare a 3D printed turbopump for a test at NASA's Marshall Space Flight Center. The turbopump was tested at full power, pumping 600 gallons of semi-cryogenic liquid methane per minute, ...

Propulsion provider Aerojet and partner Florida Turbine Technologies (FTT) have completed preliminary design of the turbopump assembly for a new upper-stage rocket engine under consideration by the ...

Based on a request from the US Air Force, a new Upper Stage engine – to ultimately replace the RL-10 used by the Atlas V and Delta IV – has made another advance, as Aerojet – one of the competitors to ...

There are plenty of rocket experimenters toying with various liquid-fueled contraptions at the moment, and [Sciencish] is one of them. He grew tired of using air-pressurized fuel delivery systems in ...

NASA has previously tested simple 3D-printed rocket components, such as combustion chambers and fuel injectors, but if the technique is to be practical, it has to cope with more complex items. Case in ...
