In Russia, tests of an unmanned aerial vehicle (UAV) VM “Dan” M with an MGTD-125E engine, the main elements of which were printed on a 3D printer, took place, according to the Foundation for Advanced Study (FPI).
The first demonstration flight of a jet UAV took place in the Astrakhan region. “The flight duration was 19 minutes, the aircraft reached a maximum speed of 676 kilometers per hour at an altitude of over two thousand meters,” writes FPI.
It is noted that the takeoff weight of the VM “Dan” M is 370 kilograms, and the 22-kilogram MGTD-125E is capable of developing a thrust of 125 kilogram-forces. According to the FPI, the parts of the combustion chamber, nozzle apparatus, jet nozzle and the inlet part of the power unit were manufactured by an additive method from Russian high-heat-resistant metal-powder compositions of aluminum, nickel and cobalt alloys.
In July, Andrey Grigoriev, general director of the FPI, said that in August, at the Army-2020 International Military-Technical Forum in Russia, a cyclolet will be shown – an unmanned vertical take-off and landing vehicle with a carrier system based on four cyclic propellers.
In April, the head of the scientific and technical council, deputy general director of the FPI, Vitaly Davydov, said that the project of the Russian deadly robot “Marker”, first presented in October 2019, would be completed in 2021.
