So far, the design and construction of rocket motors have been a complicated undertaking, requiring a lot of work and expertise. The situation, however, has changed the use of 3D printers, which, as it turns out, can do it faster, better, and create elements that are far more useful than those produced by existing methods.
NASA has been around for some time now at the Marshall Space Center, testing 3D-engine rocket engine components, and has now tested the next. This time, one of the key components of the engine, the fuel turbine, was tested.
This element is able to accelerate to 90 thousand. RPM and pumping about 4500 liters of fuel per minute, which is more than 10 times more than consuming jet engines during take-off. During the tests, the pump was also exposed to extreme temperatures, from 3300 to -240 degrees Celsius, to see how it would behave during the flight, both in the atmosphere and in the open air.
This type of rocket engine technology is much more useful to the space industry as it performs much more efficiently. It is also important that the pump coming from the 3D printer contains half the moving parts and that its production time is half as short as the traditional methods.
