The Tech Behind Preventing Airplane Bird Strikes

the4thdimension writes "CNN is running an article covering the technology used at Sea-Tac for preventing airplane bird strikes, like the one that occurred weeks ago to the now famous Flight 1549. The hardware used ranges from low-tech pyrotechnics, to netting, to lasers, to avian radar. Using a combination of all these technologies, Sea-Tac believes they save hundreds of thousands of dollars per year in avoiding dangerous bird strikes."

    The secret to preventing bird strikes is to constantly gauge their needs and demands. As long as you regularly meet those needs without giving in too much, you can keep them from striking.

    Then you get birds stuck in the titanium chicken wire, and the engine has a good shot of now sucking in both the bird and the chicken wire. On top of that, even if that doesn't happen, you're still seriously impeding air flow into the engine which is needed to make the engine function.

    And according to Wikipedia at least, a typical modern jet engine shunts dead bird parts through a bypass rather than through the engine.

  4. It was more than one bird by 140Mandak262Jamuna · · Score: 5, Interesting
    The pilot of 1549 was saying his view was completely filled with birds and he ran into a whole flock of birds. All these techniques to buzz/fry one bird is not going to cut it. But the birds do have a motive in avoiding the plane as much as the plane wants to avoid hitting the bird. So if we just let the birds know a plane is on collision course they will move away. They are a lot more agile than an airliner.

    Most birds use parallax to get their 3D cues. Think about it, for something that lives in full 3D space, most birds do not have stereoscopic vision. Their eyes are wide apart facing opposite directions with very little overlap. If the plane approaches the birds in such a way that the bearing (direction, angle) of the plane as seen by the bird is constant, the bird thinks the plane is part of the background, it is at infinity! That is why they don't take evasive action. If we put a series of LED lights along the length of the plane and turn them off and on to produce streaks of lights running from nose to tail, it will interrupt their visual cues and make the plane stand out from the background. That will give cues to the birds about the real position of the airplane. They will avoid us, we don't have to avoid them.

    Dogs would be useful but it'd be a lot more fun if we could get a pterodactyl out there hunting the birds.

  10. Major point they're missing by Guysmiley777 · · Score: 5, Informative

    The bird strikes did not occur near the airport. They occurred 2 minutes after takeoff at an altitude of 3,000+ feet. The aircraft was miles from the airport when it lost power.

    The techniques they use are valuable because they reduce the bird density right around the airfield, and having a multi-engine failure like what happened with 1549 had would be MUCH less survivable if it occurred immediately after takeoff.

    Simpler than that; use Darwinian natural selection. Simply invent a machine the size and shape of a jet-aircraft which zooms around airports emitting loud jet turbine noises, and sucks in and shreds any bird not conditioned to keep well away from such stimuli. Rinse and repeat.

    They already do. The problem is traffic management.

    Airlines would love to save gas by going right up to the point where they can cut the engines to idle and then coast in to the airport. But since everyone wants to do that it would create a traffic nightmare. They need a way to line everyone up on the same runway so they can space them out properly. And if it's cloudy, you need a way to make sure you can be lined up on your runway when you come out of the clouds. So they make instrument approaches that use navigation aids on the ground or GPS.

    This works well at small airports, but busy ones have too many planes coming in so they make these things called a Standard Terminal Arrival Route (STAR). Everyone flies to one of these routes and then they join up to an instrument approach to land.

    Airlines would love nothing more than to save gas by doing exactly what you suggest, and people on the ground would also like to not have airplanes buzzing their house at all hours of the day, but it's not even close to practicable.
