As part of the project aimed at creating entirely indigenous gas turbines, Power Machines completed the first stage of developing the new wheel space part for the GTE-65.1 gas turbine.
The basic design analysis of the GTE-65.0 sample manufactured by "Power machines", was carried out by the Lyulka Experimental Design Bureau (branch of ODK-UMPO PJSC).
Based on this analysis, the specialists of the design bureau established a concept for the upgrade of the turbine wheel space part. The concept is already being implemented. Namely, new gas-dynamic surfaces of the moving and fixed blades of the GT-65.1 turbine have been developed. Changing the blade profiles should lead to an increase in the efficiency of the turbine wheel space part to achieve the target parameters of the GTE-65.1 project.
The next stage which will be completed by the end of 2020, includes development of a new blade cooling system. In 2021, it is planned to release a pilot batch of first-stage blades to be tested at the testing facility of NPO CKTI named after I.I. Polzunov. The blades will be manufactured using additive technologies - 3D-printed, which is a new experience for Power Machines.
