Succesfull test flight with 3D printed gas turbine engine

At the Kazanbash Aviation Center in Tarastan, a test flight of a 3D printed gas turbine engine has been carried out successfull. It is the first flight in Russia of the MGTD-20 gas turbine engine. The flight of the unmanned aerial vehicle (UAV) of 40 kilograms reached an altitude of 170 meters and a maximum groundspeed of 154 km/h.


The 3D printed engine has been developed in a joint project of the Foundation for Advanced Research and the Federal State Unitary Enterprise “VIAM”. The project aims to develop a new generation materials for additive manufacturing technologies for the manufacturing of structural elements of aircraft and rocket engines. The project was launched in November 2015.

Metal-powder composites

The engine has been manufactured by fusion of a metal-powder composition of heat-resistant and aluminum alloys. A number of developed alloys surpass foreign alloys by more than 20% in strength characteristics. Thanks to the new technology, the production time for the main engine elements has been reduced by 20 times, while the cost of their production has been reduced by more than two times.

More than 100K rpm

The testet 3D printed gas turbine engine has a thrust of 22 kgf.  The UAV’s wingspan is 3 meters, the take-off weight is 40 kilograms, taking into account the payload mass of up to 10 kilograms. During the first test flight the device passed in autopilot mode along route points at an altitude of 170 meters, reaching a maximum ground speed of 154 kilometers per hour, after which it made a successful landing. The maximum engine speed was 101,600 rpm, the working speed was 58,000 rpm.
