For the Birds

[Hank]

Hello- I was researching the recent changes to the Rolls-Royce Trent series of turbines when the subject of bird ingestion came up.
With a large forward facing area, resistance to bird ingestion is required. Ingestion of a number of medium size birds has to be demonstrated by running an engine at take-off power and requiring it to ingest four birds within the space of one second. The engine continued to deliver power, accelerating and decelerating for a total period of thirty minutes to simulate the likely operating procedure following a severe ingestion incident.
