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?
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.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?
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?
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.
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.
Hopefully a great invention will come out of that discussion.
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.
Uh, you do realize the cabin, including the cockpit, is pressurized, right? Opening that window is asking for major trouble.
And besides, the AFS is what's flying the plane and the ILS is what lands the plane.
