II. Types of Failure
- Mechanical failure
- Wear and tear on moving parts
- Wear and tear on moving parts is a common type of mechanical failure in micro gas-turbine engines. It occurs when the surfaces of moving parts come into contact with each other, causing friction and abrasion over time. This can result in the erosion or loss of material from the parts, which can lead to a decrease in performance and an increase in the risk of failure.
Some examples of moving parts that are susceptible to wear and tear in a micro gas-turbine engine include:
- Bearings: Bearings are used to support and reduce friction in the rotating parts of the engine. Over time, the surfaces of the bearings can become worn, leading to increased friction and heat generation. This can cause the bearings to fail, leading to damage to other parts of the engine.
- Seals: Seals are used to keep fluids and gases from leaking out of the engine. Over time, the seals can become worn, leading to leaks and decreased performance.
- Turbine blades: The turbine blades are responsible for converting the energy of the hot gases into mechanical energy. Over time, the turbine blades can become worn, leading to a loss of efficiency and an increased risk of failure.
Preventive maintenance, such as regular inspections, lubrication, and replacement of worn parts, can help to reduce the risk of wear and tear on moving parts in a micro gas-turbine engine. Also, using high-quality materials, such as special coatings, can increase the life of the engine parts.
Fatigue failure in structural components
Fatigue failure in structural components is a common type of mechanical failure in micro gas-turbine engines. It occurs when a component is subjected to repeated loading and unloading cycles, leading to the accumulation of small cracks in the material. Over time, these cracks can grow and eventually lead to the failure of the component.
Fatigue failure can occur in a number of structural components in a micro gas-turbine engine, such as:
- Rotor shafts: The rotor shaft is responsible for transmitting the torque from the turbine to the generator or compressor. Over time, the shaft can become fatigued and eventually fail.
- Blades: The blades in the turbine and compressor sections of the engine are subjected to repeated loading and unloading cycles, which can lead to fatigue failure.
- Casings: The casings of the engine are designed to contain the hot gases and protect the internal components. Over time, the casings can become fatigued and eventually fail.
One way to prevent fatigue failure in structural components is to design them with a sufficient safety factor, meaning that the component is designed to be stronger than what is needed for normal operation. Additionally, regular inspections and monitoring of the engine can help to detect small cracks before they have a chance to grow and cause failure.
