I fly with a couple of local clubs here. If anyone tried to fly near an airport, or intentionally near a manned aircraft they'd be beaten senseless.

Some of these guys love to fly and any asshat that threatens their hobby is in deep shiate

The One True TheDavid: Someday a hobbyist will invent a drone bomber. Or a fleet of baby kamikazis. Or a flying machine gun.


We already have that last one.  It's called the A-10.

WhyteRaven74: In the bird strike test, that's a bird carcass being launched into the engine from a pneumatic cannon.


Well, as long as everyone's piling on TFA, the second video isn't a bird strike test, it's a blade out test. The orange thing on the front fan disc at the beginning is a bomb, and the fun starts when they blow it up to show what happens when a blade fractures at speed.

TuteTibiImperes: Why don't plane engines have grills to protect against things entering them?  Would it disrupt the air too much and reduce engine efficiency, would they be ineffective at the speeds the planes travel, or is there some other reason?


Because you'd rather have "something" get pulled into the engine at 500-MPH than "something plus a grill." It's not like a grill is going to hold up to a collision at those speeds.

And yes, efficiency is #1. You should see the brake systems for large jets. Not an ounce is wasted, and they they work reliably. Very good example of how to refine a product right up to the edge of what is possible.

Because it would suck the bird right thru the grill. A friend was working above a live jet engine on a carrier flight deck. He could feel the engine pulling his boot off.

He was new

gibbon1: WhyteRaven74: Also a bird has certain properties that a drone doesn't have.

Back in school one our instructors showed us a film of a jet engine sucking in a small bolt.  It was taken with a high speed camera so you can see what happens in slow motion.  I think the thing got in two rotations of the turbine before tears started appearing in the casing. Unlike a duck a drone usually has four electric motors, the engine isn't going to like those very much.

Also the FA gets it's wrong. Losing an engine during takeoff is one of the most dangerous things you can have happen.


Came here to say that. A twin engined plane losing an engine at take off can be very very bad. There is a gap between the point where they can slam on the brakes and stop before the end of the runway and the point where they are going fast enough to take off and climb out on one engine. Ingest a bird between those two points and you are screwed.

Hit a bird at 20k feet (not that there'd be many birds at that height) and you'd have plenty of time to plan your landing, talk to ATC, etc.

Imagine the grill you'd need to absorb and/or deflect a 12 pound bird, and remain aerodynamic during all stages of flight.  It'd have to be huge, both to have the structural strength necessary, and to allow enough air through.  For example, a 777 engine takes in more than 2,000,000 CFM of air at full power.  I can't even imagine a way to deflect birds while still allowing 2 million CFM of airflow.

Then you'd have a drone and a grate ducked into the engine

Hmmm...this should be investigated.
