Final answer:
Fire detection systems, including flame detectors and temperature sensors, are installed on the engine nacelle, core, and pylons for early warning and prevention of fires.
Step-by-step explanation:
On the engine Nacelle, fire detection systems are typically installed to ensure safety. These systems often include flame detectors that can sense the presence of a fire by monitoring the level of infrared radiation emitted. Additionally, smoke detectors may be installed to detect the presence of smoke and provide an early warning of a potential fire.
In the core of the engine, fire detection systems are essential for early warning and prevention. These systems usually consist of temperature sensors that monitor the heat generated within the engine core. Sudden increases in temperature can indicate the presence of a fire. Fire detection systems may also be installed on the pylons, which are the structures that attach the engine to the wings of an aircraft. Similar to the nacelle and core, these systems usually include temperature sensors and flame detectors to detect fires or overheating on the pylons.
