Bird Strike Detector for Jets??

What are the immediate consequences of bird strike (other than ending up in the river) - perhaps look for them instead. Accelerometers looking for signature of a bird going into the rotor??

OK... so your bird strike light goes off... what, as a pilot, are you going to do about it? :-) I imagine pilots already try to avoid flocks of birds whenever possible...

It would be easier to place the detector at the back of the engine and detect that flaming bits fo bird came out followed by a decrease in thrust.

We could also put an impact detector that lit up a light that says "You just crashed".

If we are going to put any sort of bird detector on the engine, it should be connected to the weapons grade laser that vaporizes it before it goes in.

The biggest problem would be distinguishing between "significant" ingestion (e.g. a whole flock of geese in one go) and the hundreds of pigeons, seagulls, etc which go through the engines day in, day out.

Too bad leftist weenies won't fit ;-)

We already have one. THe airplane all of a sudden gets very, very quiet.

You can smell fried sparrow and fried deicing fluid in the cabin from the engine bleed air used to pressurize the cabin. Bleed air comes off the compressor stage. Been there, done that, got the tee shirt. The sparrow flock was during climb out, just after rotation, at a point near/on dead man's curve in a 737. I'm still here, so the systems worked as designed. I just felt a slight thump, heard a clicking sound, we yawed a bit, and then a few seconds later a nasty smell. It was not worrisome until the pilot announced the event, after he leveled off. He sounded less then concerned.

But by the time you sense the event, either your turbines are already spinning down, or things are fine.

I have not been aboard one when they did not thaw the test chicken, however. Modern test birds are polymer replicas, thanks to PETA etc.

Interestingly enough, the pilots on the airliner blog I read, all agreed the birds have a right to be air space users, and didn't have a grudge with them.

t.

yeh a loud mechanial noise followed by silence and smell of dead birds should be enough ;)

-Lasse

Do you mean to say that the engine puking its guts out its own exhaust aren't enough of an indication that something is wrong?

I was thinking it might be useful to differentiate between a bird strike and some other type of engine failure..

But yeah..however an engine fails, the pilot still has to deal with it bird strike or not.

' The greatest loss of life directly linked to a bird strike was on October 4, 1960, when Eastern Air Lines Flight 375, a Lockheed L-188 Electra flying from Boston, flew through a flock of common starlings during take off, damaging all four engines. The plane crashed shortly after take-off into Boston harbor, with 62 fatalities out of 72 passengers. Subsequently, minimum bird ingestion standards for jet engines were developed by the FAA.'

Perhaps the little birdies can be counted too. If there's no following engine failure alarms, alls well. Perhaps the sparrows, pigeons, seagulls can be logged which may help with the engine maintenance schedule. After 'food processing' hundreds of birds, there's probably some wear.

When the 'something sucked into engine alarm' goes off and then there's the following engine failure alarms then the pilot can put the data together and deal with it..

Perhaps in a failure investigation, it might be useful if a 'thing sucked in engine' detector logged a thing sucked got sucked into the engine..

On January 15, 2009, US Airways Flight 1549 from LaGuardia Airport to Charlotte/Douglas International Airport ditched into the Hudson River after experiencing a loss of both turbines. It is suspected that the engine failure was caused by running into a flock of geese at an altitude of about 975 m (3,200 feet), shortly after takeoff. All 150 passengers and 5 crew members were safely evacuated after a successful water landing.[29] The NTSB has yet to publish a report on this incident.

But was it birds for sure???

You ought to read or listen to the news once in a while.

While there is not yet a formal report, it has been stated that BIG bird remains were found in BOTH engines.

One good thing that came out of all of this is that there's been a new drink named after Capt. Sullenberger:

The "Sully" - two shots of Grey Goose and a splash of water.

Yeah..I don't read or see much news..

Anyways..Now there's a pilot I'd ask if it would be useful to have a 'thing detected passing into engine' alarm.. It would take some of the mystery out of 'Why are the engines not working?'

It would give them something to write up in the maintenance log!

engine exhaust temps are used to indicate problems. and often,the engine parts come out the SIDES,not the exhaust. One jetliner had them come into the passenger compartment,IIRC,a few people were killed by them.(a tail mounted engine pair)

I'll wager a whole raft of lights came on in the cockpit after flight

1549 struck those birds.
