Additive technologies is a rapidly developing area of production. One of key advantages is the possibility of creating details of almost any geometric shape. A perspective example of their use, where the shape means a lot, could be micro turbojet engines. Geometry requirements for the air-gas channel of an engine as well as the presence of parts in the design with a sharp transition of the functional properties of elements impose constructive limitations on both individual details and the structure as a whole. The use of additive technologies allows you to avoid a number of limitations and opens up a wide range of opportunities for a developer to optimize existing designs and create new layouts.
On International Aviation and Space Show (MAKS) 2017 our company presented the prototype of a micro turbojet D200 engine. The engine is designed according to the classical scheme for this type of engines: a single-stage centrifugal compressor with a channel diffuser, an annular combustion chamber with an evaporative fuel supply system, a single-stage axial turbine. Control is provided by digital control system with all necessary tools located beneath the body.
This engine is able to reach the thrust of up to 21kgf. The engine is intended to be utilized of local market UAV manufacturers
