Every time I see news of a bird killing a jet engine I immediately wonder why some sort of screen cannot be placed over its inlet to either catch the bird or at least dice it into small pieces. Why is this not possible?
SteamKing said:Because the screen would probably be sucked into the engine along with the bird after the strike, causing even more damage to the engine. Also, the presence of the screen would disrupt and reduce airflow into the compressor, making the engine less efficient.
No.drshi said:Surely a screen could be made to withstand the impact of a bird at the low altitude and reduced speed where such impacts occur, no?
drshi said:I, too, am not stupid. I have researched your claim and can find no indication that any such "investigation" has been conducted by the aviation industry or the FAA. Your certainty must mean that you are aware of such studies, so I would greatly appreciate any references you can offer to support this. Merely "thinking about" solutions does not constitute research. Were the Defense Department to insist that the industry solve this problem, how much do you want to bet that it would be solved?

If you want to design a "screen" that would stop that, and sill let the air through, feel free to try. Engineers who work in the industry have better things to do with their time.A 12-pound Canada goose struck by a 150-mph airplane at liftoff generates the kinetic energy of a 1,000-pound weight dropped from a height of 10 feet.
That is hysteria, not engineering. As the Boeing link says, the number of people killed by birdstrike incidents is of the order of 10 a year. That's not exactly a large proportion of the total deaths in aviation accidents - about 1500 per year in the US alone, not counting the rest of the world. And in most years, all of those US deaths were "general aviation" accidents, not paying customers on commercial flights.What aerospace engineer would be content with the knowledge that a BIRD can bring down a giant jetliner and kill hundreds of people?
drshi said:but I passed up one because it was merely a forum, and this time I looked at it and found a wealth of info even including a photo of an actual screen tested by Pratt and Whitney on an F-119 engine.
drshi said:I've had enough holier-than-thou condescension from you people. I'm switching over to the airlines.net forums where people are willing to actually discuss problems rather than make excuses why they won't. Hasta la vista, Babies.

SteamKing said:That's why they shoot frozen chicken carcasses at the cockpit windows to simulate a bird strike. If a strike were to seriously injure the pilots, that means big trouble for the plane.
jarcentales1 said:Uh, you do realize the cabin, including the cockpit, is pressurized, right? Opening that window is asking for major trouble.
Are you certain about that.
Ask a pilot.

And besides, the AFS is what's flying the plane and the ILS is what lands the plane.
A jet-engine bird strike occurs when a bird or other wildlife is ingested into the engine of an aircraft. This can cause damage to the engine and potentially lead to an emergency landing.
Jet-engine bird strikes are relatively rare, but they do occur. According to the Federal Aviation Administration, there are an estimated 14,000 bird strikes on aircraft in the United States each year.
The damage caused by a bird strike can vary depending on the size and type of bird, as well as the location and speed of the aircraft. In general, a bird strike can cause damage to the fan blades, compressor, and turbine of a jet engine.
There are several ways to improve jet-engine bird strike protection, including installation of bird deflectors on the aircraft, using radar systems to detect and avoid birds, and implementing stricter bird control measures around airports.
Yes, there are regulations and standards in place to ensure the safety of aircraft from bird strikes. The Federal Aviation Administration has specific guidelines for bird strike protection, and aircraft manufacturers must also adhere to these standards during the design and testing of their engines.
