Launcher Successfully Tests its 3D Printed E2 Rocket Engine in Full Thrust

When we talk about the use of additive manufacturing in the aerospace sector, we cannot avoid mentioning the US company Launcher. In the past, the company, founded in 2017, has been able to generate a lot of attention for itself with its activities around the development of rockets designed to carry small satellites into orbit. Now, Launcher has announced that they have successful demonstrated nominal thrust, pressure and oxidize/fuel mixture ratio for the first time with their 3D-printed E-2 rocket engines – a great milestone for the company. We took a closer look at the successful test of the launcher rocket.

The countless tests were carried out at the NASA Stennis Space Center – up until now without the promised success. However, this was no longer the case on April 21st, 2022, when Launcher’s E-2 liquid rocket engine was able to demonstrate successful full thrust, notably measuring 10 metric tons of thrust (22,046 lbf), 100 bar (1,450 psi) of combustion pressure and a highest performance 2.62 propellant mixture ratio for LOX/Kerosene at 100 bar of pressure. Next, the closed-cycle, high-performance liquid rocket engine is expected to undergo a three-minute test with the integrated E-2 turbopump in the fourth quarter of 2022.
