Narrative:

Immediately after rotation; aircraft ingested a seagull in the left engine. The engine had several (estimated 15-20) compressor stalls. The engine was useless and the flight was essentially a single engine operation. I was able to climb out at V2 during the compressor stalls that caused the airplane to shake violently (think severe turbulence). An emergency was declared and we were vectored to ZZZ and landed safely. High speed abort was not an option. I saw the birds at about 100-110 KTS and at that speed I am not confident that I would have been able to stop the aircraft on the remaining runway.

Original NASA ASRS Text

Title: GULFSTREAM G11B FLT CREW HAS A BIRD INGESTED IN THE L ENG DURING TKOF; DECLARES EMER AND DIVERTS FOR LNDG.

Narrative: IMMEDIATELY AFTER ROTATION; ACFT INGESTED A SEAGULL IN THE L ENG. THE ENG HAD SEVERAL (ESTIMATED 15-20) COMPRESSOR STALLS. THE ENG WAS USELESS AND THE FLT WAS ESSENTIALLY A SINGLE ENG OP. I WAS ABLE TO CLB OUT AT V2 DURING THE COMPRESSOR STALLS THAT CAUSED THE AIRPLANE TO SHAKE VIOLENTLY (THINK SEVERE TURB). AN EMER WAS DECLARED AND WE WERE VECTORED TO ZZZ AND LANDED SAFELY. HIGH SPD ABORT WAS NOT AN OPTION. I SAW THE BIRDS AT ABOUT 100-110 KTS AND AT THAT SPD I AM NOT CONFIDENT THAT I WOULD HAVE BEEN ABLE TO STOP THE ACFT ON THE REMAINING RWY.
