Definition
The pressure of the gases inside the combustion chamber (burner section) of a turbine engine. Burner pressure is used as an indicator of engine power output on some turbine engines, where a cockpit gauge displays this pressure for the pilot to monitor and set thrust.
Plain English
How hard the burning gases are pressing inside the part of a jet engine where the fuel is burned. On some jets, the pilot watches this pressure on a gauge to see how much power the engine is making.
Context Anchor
Seen in turbine engine operation, engine testing, and maintenance troubleshooting.
Derivation
“Burner” here refers to the combustion area of a turbine engine, not a cabin heater or a stove burner. “Pressure” means the force of the air pushing inside that area.
Why Pilots Care
On engines that use it, burner pressure is the primary thrust reference. Setting takeoff or climb power means setting a target burner pressure, so understanding what the gauge is showing matters for getting the right power without over- or under-thrusting the engine.
Grounding Statement
In a turbine engine, air is squeezed, mixed with fuel, and burned; burner pressure is the pressure in that burning area.
Intuition Check
Burner pressure does not mean heat from a heater or flame size. It means air pressure inside the engine’s combustion area.
Example Sentence 1
The pilot advanced the throttles until burner pressure matched the takeoff value listed on the performance chart.
Example Sentence 2
Low burner pressure can indicate a problem with compressor discharge or fuel nozzles.
