Abstract

The new approach in methodology on the calculating and normalizing safety factors for different parts and knots of the engine, based on kinematic model of destruction is offered. As examples are defined a stock of a rotor on critical velocity, a stock on a carrying capacity of the impeller of the jet turbine and margin of safety of a bimetallic enclosure of chamber rocket engines.

Keywords:

safety factor, critical velocity, bearing capacity, enclosure, rocket engines, rotor, the turbine.
