This report describes a formal method to quantify structural damage tolerance and reliability in the presence of a multitude of uncertainties in turbine engine components. The method is based at the material behavior level where primitive variables with their respective scatter ranges are used to describe behavior. A formal method is described to quantify structural damage tolerance and reliability in the presence of multitude of uncertainties in turbine engine components. The method is based at the materials behavior level where primitive variables with their respective scatters are used to describe that : Christos C. Chamis. Damage Tolerance Philosophies are being used today in the Design, Development, and Life Management of USAF turbine engines. The establishment of a Damage Tolerance Philosophy and implementation of a Fracture Control Program has been an integral part of the USAF turbine engine development process since Cited by: 3. The article presents the analysis of damage to gas turbine blades influencing the reliability of aircraft turbine. engines. Characterised are methods of non-destructive testing and capabilities of applying them to the computer-. aided objective diagnosing of condition of blades [3].

Sources of damage to aircraft and gas turbine engines are illustrated in Figure 9. Damage due to manufacturing defects, tool drop, handling, installation, and engine maintenance are of primary concern for CMC components in gas turbine engines. fatigue and fracture reliability of gas turbine engine structures. These include crack initiation and crack growth models, non-destructive evaluation, probabilistic risk assessment File Size: 2MB. The approach is illustrated for risk prediction of a representative gas turbine engine disk. The results can be used to gain a better understanding of the AC and how the problem is solved using the probabilistic damage tolerance framework provided in by: 2.

perform improved deterministic and probabilistic damage tolerance assessments. The methodology combines a software tool for performing fatigue crack growth (FCG) life and fracture reliability assessments of turbine engine components with another software tool for creating high fidelity crack growth simulations.

Reliability-Based Damage Tolerance Methodology for Rotorcraft by: gas turbine engine development process. The spin rig test could also be performed under a life extension study to estimate the real fatigue life of hot section engine components. The life extension studies with use the “damage tolerance” philosophy are nowadays performed for aircraft, due to the fact that the cost of a credible life.
