With 3D Printing Parts Of Orion Mann Spacecraft Propulsion System Test Successfully
Nov 06, 2018

Orion spacecraft manned module in its service module after the separation, reaction control system is to guide its the only way to prepare back into the atmosphere and then landing.The system consists of 12 MR - 104 - g of hydrazine propulsion, each propeller thrust is 160 pounds, the system will also ensure the correct positioning of spacecraft (the heat shield to the below) in order to re-enter, and remained stable in the process of decline.


EM - 1 the design of the reaction control system thruster is based on the Exploration of 2014 Flight mission after Flight Test of engine Test - 1, on the basis of the enhanced system has a stronger structure and higher thermal stress and less weight.Improvement of manufacturing process to update the system, in order to cope with change of load, and ultimately improve the load.In EM - 1 quest, a without destroying the Orion spacecraft will launch to the distant retrograde orbit around the moon, then return to earth.Next, is EM - 2 exploration missions, Orion will take astronauts during the flight near the moon.

Aerojet except reaction control system integration for space launch system (SLS), the rockets also provide the main level and the superior liquid engine, and disposable engine, disposable engine shortly after activation of SLS 2 will launch abort system is separated from the unit module of Orion.At the same time, the Aerojet European service module integration for Orion also provide auxiliary thrusters (ESM), and support the change led by NASA shuttle OMS - E engine project.

According to the market observation, the sky Orion spacecraft using 3D printing unit, is the Aerojet integration used in spacecraft materials manufacturing technology of the "tip of the iceberg".Previously, Aerojet integration has a variety of through metal 3D printing manufacture rocket engine parts passed the test.Such as:

Announced in October 2018, Aerojet integration as the national aeronautics and space administration (NASA) and the defense advanced research projects agency (DARPA) to make a new type of hypersonic engine has successfully pass the test.Through the test of engine as a "new dual-mode ramjet engine/super fuel stamping (DMRJ) engine", Aerojet integration, the past achievements and increase their in the 3D printing/material manufacturing progress, the combination of manufacturing the next generation of hypersonic propulsion system becomes a reality.

In April 2017, Aerojet integration announced its full size of 3D printing copper alloy thrust chamber components ignition test successfully.According to the 3D valley of scientific understanding, 3D printing is Aerojet integration optimization RL10 engine of a "killer app", in the course of the development of a new generation of RL10 engine, Aerojet integration using powder bed in selective laser melting 3D printing technology made of copper alloy thrust chamber parts.

In March 2015, Aerojet integration in the Sacramento test center successfully completed the key components of the AR1 turbo engine hot test.AR1 rocket engine of single pulse (single - element), the main nozzle was made entirely using 3 d printers.

AR1 rocket engine of single pulse (single - element), the main nozzle was made entirely using 3D printers.AR1 is a 500000 pounds of thrust in development level of liquid oxygen/kerosene engine, the United States wants to use it to replace the Russian RD - 180 engine.Injector is made of selective laser melting (SLM) technique, 3D printing proved to be compared with the traditional manufacturing technology with low cost fast to create complex engine parts.Only in the main injector, a 3D printing will reduce the time of delivery of spare parts for nine months, and reduce the cost of 70%.
