🔍 Key Concepts

• Gas turbine air intake system operation and purpose of blow‑in doors • Relationship between air inlet pressure and engine airflow demand • Effects of blockage, icing, or restriction in the air intake path

💭 Think About

• Think about what happens to pressure in the intake duct if the normal intake openings become partially blocked while the engine is still demanding the same amount of air. • Which condition would make it necessary to provide an alternate air path (via blow‑in doors) to protect the compressor from starvation or surge? • Consider which listed condition is most likely to be abnormal and hazardous for a gas turbine: higher inlet temperature, higher exhaust pressure, higher inlet pressure, or restricted intake due to ice.

✅ Before You Answer

• Verify what blow‑in doors are designed to do: do they protect against too high or too low inlet pressure at the compressor face? • Check which choice describes a situation where normal airflow is restricted into the engine. • Eliminate any options that would normally be managed by other systems (e.g., temperature control or exhaust backpressure control) rather than by opening blow‑in doors.
