why an airplane crashes if it get struck by a bird?

Answer 1

well most planes do not crash when birdstruck. Anyway the high relative velocities of the two moving objects make even from the small bird a possibly dangerous projectile. Most likely the bird will just smash at the plane surface. occasionally it can be sucked int o the engine, where occasionally it may cause flameout or fire. Another problem arises when the bird hits the windshield and makes it into the cabin.

Answer 2

It would depend on the size of the aircraft, the size of the bird, and where it strikes the plane. All modern aircraft are tested against birdstrikes and offer some degree of protection. When engines are tested they are required to have real birds (usually store bought chickens that are thawed out) shot in to the engine to test for susceptibility to damage. Pilot windshields are also heated, primarily to avoid icing and fogging, but to also make these rather thick structures slightly pliable in the cold air and therefore more bird stike resistant. Therefore most large aircraft shouldn't be overly susceptible to major effects from hitting a bird.

The problem lies in that some birds are really big ( an albatross!) and might therefore exceed the design rating of some of the engines. Aircraft might also fly through a flock of birds which will make many small birds exceed the engine strength by sheer force of numbers. Pilot error could also be a factor- hitting a bird can be quite startling and if it also causes engine failure,structural failure, or windshield penetration then things could go badly in a hurry....

Answer 3

Most aircraft don't crash after a birdstrike. It depends on the size of the bird and the size of the aircraft. The Air Force loses jets to birdstrike and lost a B-1 years ago. A B-1 is a large aircraft and the bird entered at the wing root and started a fire. Just flaming an engine doesn't generally bring an aircraft down unless of course you only have one (F-16). Large airliners rarely come down to birdstrike. The other thing is that birdstrike is only an issue at lower altitudes. Ever see a bird at 30,000 feet?

The takeoff and landing are the most hazardous areas for commercial airliners. Military jets can spend quite a lot of time down "in the weeds" and are more prone to dangerous contact with something big like a buzzard, stork or the like.

Answer 4

Several reasons.
First off, we call it "bird strike damage".
If the plane is flying fast enough, a bird can go through the windshield, possibly disabling the pilot (imagine flying solo).
On a jet engine, it can go into the engine (through the intake), and FOD (Foreign Object Debris/Damage) out the engine, not good on a single engine plane, like the A7 or the F16.
On a prop engine, it could damage the prop, or at least affect the balance of it, shaking things apart in the worst case scenario.
Also, the early B1A Bombers had a problem with bird strike to the leading edges of the wing and tail, some severing lines and cable, until reenforced with Kevlar blanketing.

Answer 5

Just to dispel the myth that some are propagating... A bird ingested by the engine of a large multi engine aircraft (like an airliner) will almost never cause a crash! It will most likely cause the failure of the engine but those aircraft are designed to fly just fine with the loss of an engine.

Now if you fly through a whole flock of birds and flame out all your engines then good luck! Not your day i guess.

Answer 6

A starling has the highest density of all birds. There are larger birds but none are as dense. The starling hitting an aircraft on final doing around 140kts hits with over 2 tons of force. A bird strike can take down an aircraft. Case in point, at Elmendorf AFB in Alaska, a KC-135 was downed on takeoff when they hit a few geese that took off as they were. They crashed a half mille off the end of the runway.

Answer 7

Well we lost an AWACS outta Shemya once due to a Bird strike, and that's a Converted 707. They caught multiple Goose in 2 Engines on takeoff. Lost power from those engines and crashed.

If you think about it, you have a 5-15 pound object being hit at 150-500 knots, It's gonna do damage. I've seen and repaired damage from Sea Gulls, Hawks, and even Pigeons during my service. Sometimes it was real minor stuff, Once we had to replace the entire wing leading edges, Radome, and Cockpit windows on a C-5B, when they hit a flock of sea gulls at low level.

Answer 8

Smartypants, docs annihilate species even as they locate treatments, we are attempting to get alongside amicably with different existence varieties. And FYI, length would not matter, the biggest killer of the species maximum contained in the nutrition chain is a protozoan parasite about 50 micrometers large. and attempt to get out of your techniques the concept that what works in diaper ought to paintings for a cannon. Collisions will take position even as non speaking flying entities percentage an similar airspace. from time to time the great (and humane) option is to be designed to proceed to exist a collision. Are we vaccinated or secure adverse to each and every straightforward ailments? For some we are, for some we deal with it even as struck and infrequently we lose the conflict too. even though it doesnt make you stay in a plastic sphere and an similar reasoning applies the following. whatever you imagine, in case you do a suitable study, you need to ensure that the massive "incorrect" engine, with its awe sucking for 5 inch tall ducks and smaller starlings, continues to be connected to the most secure position on earth. isn't that ironical, or are we, the engineers, smarter than you've expected.

Answer 9

I was a Flight Engineer on C-141 cargo aircraft. We flew into Midway island on a mission. This island is the home of the "gooney bird" (albatross). In the process of making our landing, we had one hit the wing leading edge, one hit the cowling of #2 engine and one hit the landing gear pod. We also had several near misses. None was serious enough to bring us down, but had they hit the intakes on the engines, it would have been a distinct possibility. There have been aircraft brought down by hitting a flock of birds. Whether the plane goes down depends on the type and amount of damage done

Answer 10

It would be very rare for a plane to crash because of a bird strike. Bird strikes occur at low altitude when the plane is not moving very fast. They can cause a broken window, or be sucked into an engine. And very rarely will a bird in the engine cause a problem. Usually, you just have ground bird coming out of the back of the engine, lol.
