| A method of thermal control of the breakage of the driving wheel of GTE blades with additional thermal loading of the weakened section of the blade on the set frequency of rotation by means of an electroheater located in the loading site (a root part or the lock) of blade is developed. The method of blade breakage consists in the redistribution of the stresses in the given section of the blade at additional thermal loading and in maintenance of quasi-fragile destruction of blade on specified section on the set frequency of rotation of a rotor. The calculated modeling of control breakage of blade is carried out. The offered method of thermal control breakage of blade has been used at carrying out of test containment fan casing of the aviation engine on the spin rig. |
