Triebwerksgrenzen

Triebwerksgrenzen, or engine limits, refer to the operational boundaries within which an aircraft engine can safely and effectively function. These limits are crucial for ensuring the engine's longevity, performance, and safety. They are typically defined by several key parameters:

Firstly, the engine's power output is limited to prevent overheating and excessive wear. This is often expressed as a percentage of the engine's maximum power, such as 100% for takeoff, 90% for climb, and 80% for cruise.

Secondly, the engine's rotational speed, or RPM, is also limited. Exceeding the maximum RPM can lead to engine damage. The limits vary depending on the engine type and its intended use.

Thirdly, the engine's temperature is closely monitored. Excessive heat can cause engine components to fail. Therefore, limits are set for the engine's oil temperature, exhaust gas temperature, and turbine inlet temperature.

Fourthly, the engine's fuel flow is limited to prevent fuel starvation or overfueling. This is crucial for maintaining the engine's power output and efficiency.

Finally, the engine's vibration levels are monitored. Excessive vibration can indicate a problem with the engine's components, such as a cracked turbine blade. Therefore, limits are set for the engine's vibration levels.

These limits are typically displayed on the engine's instrument panel and are adjusted by the pilot based on the aircraft's weight, altitude, and other factors. Exceeding these limits can lead to engine damage, reduced performance, and even engine failure. Therefore, it is essential for pilots to understand and respect the engine's limits.
