Abstract

Within the framework of the cooperation between BSTU «VOENMEH» and LLC «Modern Equipment» (Solver Group of Companies), a project was implemented to manufacture the main components of a smallsized gas turbine engine, evaluate the details, further test them, and also make a preliminary assessment of the application of additive technologies in aerospace Industry. As an object of research in this project was selected small-sized gas turbine engine with a calculated thrust of 10 kgf. The urgency of the choice of the object of the study is explained by the fact that at the present time unmanned aerial vehicles are actively being developed in Russia, as well as power installation for them. All the details of a small-sized gas turbine engine can be conditionally attributed to three temperature ranges of operation, which made it possible to identify a number of parts that can be manufactured by the FDM method from heat-resistant plastic. Within the framework of the project the following tasks were formulated: – Preliminary calculations of the thermal state of parts in the small-sized gas turbine engine; – Printing of parts, evaluation of manufacturing accuracy, surface quality; – Testing of parts in the small-sized gas turbine engine; – Removal of parts and defect management; – Analysis of the data obtained, conclusions and recommendations on the use of additive technologies of heat-resistant plastics in the aerospace industry. Printing was carried out at the production facilities of OOO Modern Equipment on the Stratasys Fortus 900 mc 3D printer. After removing supporting structures, the surface quality of the parts was measured and the roughness of the test elements was measured. The collected small-sized gas turbine engine was tested at the Department «Engines and power plants of aircrafts» BSTU «VOENMEH» named after D. F. Ustinov. The preliminary results of the project allow us to state that the introduction of additive technologies of heat-resistant plastics in the process of developing a small-sized gas turbine engine makes it possible to create and test various versions of structures in a short time, which will shorten the development time of such engines and theoretically increase their efficiency by reducing the weight of the structure.
