ACTUALIZATION OF THE MASS MODEL GTE WITH FREE TURBINE FOR HELICOPTERS

When performing parametric research of gas turbine engines with a free turbine, it is important to use such models that correctly reflect the influence of the parameters of the working process on the nature of the change in the specific fuel consumption and engine mass. As new GTE variants appear, it is required to periodically update the values of the coefficients, which was done in the paper

ACCOUNTING THE INFLUENCE ОF GAS TEMPERATURE IN THE MODEL OF MASSES GTE WITH FREE TURBINE FOR HELICOPTERS

The achievement of the best performance of aircraft engines in terms of economy is realized to a large extent due to the development of ever higher gas temperatures at the entrance to the turbine. There are two ways to solve this problem - the organization of systems for intensive cooling of turbine elements, and the use of new technologies and materials capable of ensuring reliable operation of all GTE elements. The article describes the nature of the effect of various elements to the cooling system of the engine masses

ТО ACCOUNT PROJECT UNCERTAINTY AT THE SELECTION VALUES OE PARAMETERS OF THE WORKING PROCESS OF GTE IN THE HELICOPTER SYSTEM AT THE INITIAL STAGE DESIGN

When designing a gas turbine engine in a helicopter system in the early stages of design, it is necessary to take into account the significant uncertainty in the values of the initial design data. This article which make it possible to simplify the process of accounting for design uncertainty
