- Abstract
- The article represents the way of research of damaged by extraneous objects propeller blades of turboprop engines. Method involves four steps that allow evaluating the technical condition of the blade and making a decision about the possibility of its further use for its intended purpose. The model provides the approach speedof extraneous objects to the propeller blades up to 2000 m/s. It allows to research the durability of other constructional elements, such as compressor blades of turbine engine, airframe components.
