The experimental results of the new approach of acoustic emission monitoring are led. To load a design element, the principle of thermal loading has been chosen: rise in temperature of the design element, and its cooling. The destruction of the main rotor blade of the helicopter in operation shown that traditional defect’s monitoring isn’t effective for the defection. The thermal loading of composite material’s elements from rise in temperature has shown the bigger efficiency of the defects detection, than long thermal influence of low (minus) temperatures. The offered approach allows applying an acoustic emission method directly in operation.
