MOSCOW, July 22 - RIA Novosti. For the first time, Russia conducted a successful flight test of an aircraft engine made by 3D printing, its production is scheduled for 2021-2022, told RIA Novosti at the Foundation for Advanced Research ( FPI ).
"In Tatarstan, on the basis of the Kazanbash aviation center, for the first time in Russia, flight tests of the MGTD-20 gas turbine engine manufactured by 3D printing were carried out. This power plant with a thrust of 22 kgf (kilogram-force) was developed within the framework of a joint project of the Foundation for Advanced Research and the Federal State Unitary Enterprise " VIAM " SSC RF with the participation of JSC NPO "OKB im. M.P. Simonov, "the press service said.
The FPI explained that a light unmanned aerial vehicle A30 developed by the NPO MP Simonov Design Bureau was used as a flying laboratory for testing the new engine. The wingspan of the drone 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, according to a given program, the device passed in autopilot mode along the 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 workers - 58,000 rpm, "the fund said.
It is specified that the production time of the main elements of the engines thanks to the new technology was reduced by 20 times, while the cost of their production was reduced by more than two times.
During the implementation of the project, a line of promising small-sized gas turbine engines in the thrust class of 10, 20, 125 and 150 kgf was developed, manufactured and tested. The start of serial production of power plants is scheduled for 2021-2022, taking into account the completion of the stage of development work in the interests of the state defense order.
A joint project of the Foundation for Advanced Study and FSUE "VIAM" on the development of new generation materials for additive technologies for the manufacture of structural elements of aircraft and rocket engines was launched in November 2015. Within the framework of the project, a technology has been created for the manufacture of parts for MGTD and gas turbine plants for industrial use by the method of layer-by-layer laser fusion using metal-powder compositions of heat-resistant and aluminum alloys. A number of developed alloys in terms of strength characteristics exceed their foreign counterparts by more than 20%
Cheaper cruise missiles, or cheaper UAV? Like the American Grey Wolf? It's a little slow.
