What safety measures are commonly implemented in gas turbine engine design?

In gas turbine engine design, adding redundancy and fail-safe features is a crucial safety measure that enhances the overall reliability and safety of the engine during operation. Redundancy means that critical systems have backup components or systems in place. For example, if one fuel pump fails, another can take over to ensure continuous fuel supply to the engine. Similarly, control systems might have duplicate sensors and actuators to prevent a failure in one system from leading to total engine failure. These additional layers of safety are essential in aviation and other industries where engine failure can lead to catastrophic consequences.

Fail-safe features are designed to ensure that if a failure occurs, the engine can still function at a reduced capacity or safely shut down without leading to dangerous situations. Implementing these measures helps to mitigate risks and instills confidence in the operational integrity of gas turbine engines, especially in critical applications like commercial aviation and power generation.
