Digital Twin of GTD as a new level of modeling capabilities

Abstract

The article describes the current state of information technology in the aircraft engine industry, and shows that the GTD digital twin is a single learnable digital system that includes a set of techniques and mathematical models that describe an engine throughout its entire life cycle: design, testing, production, and operation. The possibility of using the developed methods and tools for computer-aided design, selection of parameters, materials and structures, analysis of control programs for aviation GTE at the early stages of development, for debugging engines during testing, for diagnostics and assessment of the condition of GTEU (based on GTE) is shown doi 10.54708/19926502_2026_30111110
