Final answer:
The maximum EGT for the 3200 Hamilton APU during start is 477°C and 244°C while running. Maintaining these temperatures is crucial for the safety and efficiency of the APU.
Step-by-step explanation:
The maximum Exhaust Gas Temperature (EGT) values for the 3200 Hamilton Auxiliary Power Unit (APU) are different during start and while it is running. During the start phase, the maximum allowable EGT is 477°C. It is crucial to adhere to this limit to prevent damage to the APU. While the APU is running, the maximum EGT should be maintained at 244°C for safety and to ensure the longevity of the unit.
Similar to other engines, such as those in automobiles, exceeding these temperature limitations can lead to overheating and significantly reduce efficiency. Staying within these EGT specifications ensures both safety and optimal performance of the APU system. Understanding these limitations is essential for anyone involved in the engineering or maintenance of these units.
