Definition
The point in a turbocharger system where compressed air leaves the compressor section and is delivered, under pressure and elevated temperature, toward the engine's induction system. Compressor discharge pressure and temperature are key parameters used to monitor and control turbocharger output.
Plain English
The spot where air comes out of the turbocharger after being squeezed. By the time it leaves, the air is under higher pressure and is also hotter than when it went in.
Context Anchor
Seen in turbocharging discussions, especially when describing airflow, pressure, and temperature between the turbocharger and the engine.
Derivation
From Latin 'comprimere' (to press together) and Old French 'descharger' (to unload). Together: the place where the squeezed air is released from the compressor.
Why Pilots Care
Low or fluctuating compressor discharge pressure can indicate turbo issues such as leaks, wastegate problems, or compressor damage, directly affecting engine power.
Intuition Check
Discharge does not mean an electrical spark here. It means the flow coming out of the compressor.
Example Sentence 1
The pilot monitored compressor discharge temperature during the climb to ensure it stayed within limits.
Example Sentence 2
After landing, the mechanic inspected the compressor discharge for oil residue that could indicate a failing seal.
