SGT-A05 (gas turbine)

2018: Testing

On August 8, 2018 Siemens successfully tested the fuel mixer printed on the 3D-printer for the aviation gas turbine SGT-A05 with reduced emission of carbon monoxide gas.

Development of the turbine from the concept before testing took only seven months. The fuel mixer - very difficult part consisting from more than 20 elements and its production using traditional techniques takes away a lot of time and forces. Thanks to 3D - printing and use of nickel alloys to engineers of Siemens managed to reduce quantity of parts in the mixer to two, and production terms – approximately for 70%. Three-dimensional printing allowed to simplify a production process and to test the improved versions of construction ensuring more effective functioning of the mixer.

The mixer of fuel was manufactured in the 3D center - printing of Siemens, located in Finsponge, Sweden. Recently the command completed the first functional tests — specialists report what during the researches with original settings of a system was not revealed any problems. Experts noted significant decrease in emissions of carbon monoxide gas while a system worked at full capacity.

Reduction of emissions in the new system of Siemens is reached due to the innovative technologies of combustion of fuel. Similar technologies for decrease in emission of nitrogen oxides and carbon do not pose a threat for users and are successfully used on more than 120 engines with the general experience of 3.9 million hours as of February, 2018. Siemens notes that now, thanks to the latest 3D technologies - printings, it will be possible to continue work on decrease in number of emissions.

In 2017 Siemens implemented in production several 3D projects - printings which work in the conditions of very high loads and temperatures. All of them are successfully used in the different industries.^[1]
