"Bird strikes barely cause fatality. Well, except for the bird" Lmao!

I've known fast jet pilots have birds fly through the cockpit canopy.
Not always the engines.
Not good. 🇬🇧
That starting video was a fan blade separation test not a bird strike test.
glad im not the only one who knew that
you are right, that was a blade off test.
Ironic for a channel called 'beyond facts'
Accurate. The blade was marked not only to see the fan blade rotation but it was the blade that was selected with an explosive charge to see how the engine holds together when the blade is separated.
I used to work for United Airlines at SFO in the maintenance shop where we blended Stage 1 Compressor blades and a few others. One day an Inspector was showing me a blade that had been on a disc in an engine where there had been a bird strike. The blade if I recall was off of a Pratt & Whitney 2000 series engine. The leading edge of the blade looked like a big bite had been taken out of it or like what you might think a cannon ball might do to 38 blades. Unbelievable. Even the slightest imperfection on the leading edge of the blades can make an engine lose power.
You talk too much
The engines on commercial airlines are so interesting, everything they have to prepare for and withstand in any elements is truly an engineering marvel
There's nothing impressive about these shit crafts. It's caveman technology.
You see boys. Remember, the machine is more important than a bird.
the same goes for you, your species is worthless!
i remember bear grylls cooking crabs in the mountains of …. he defo would of said that the locals do this every year . (looking at the aftermath of bird vs engine )
Technically that machine js technically 200 people
Its not about machine
Its about safety of the pasingers
It’s not
Afaik, these bird tests are only to make sure the engine does not explode during bird strikes. Engine damages are unpreventable using current technology. But making sure , engines do not explode make sure that planes can land safely in most cases. If the engine had exploded, that's it. That's why tests are critical for approval.
Man people are amazing.. Being able to make all of this
That's what am thinking about

Cool video! Pilots landing in crosswinds is very impressive.
I worked for BA for 36 years. It is indeed true that chickens are used in engine testing but they are not live and bought from a supermarket. Unfortunately, one test mistakenly involved a frozen chicken which destroyed the engine completely!
Yes, I’ve heard of this story independently 😂
Yes and people don't stand in front of the engine to throw them in.😆 As a note I know the Air Force has a frozen chicken cannon (or at least used too) to test windscreens for jets.
Humans are stupid 🙄
My uncle worked for a company that loaned their air cannon they used for testing windshields to a company in Europe. They tested them by shooting whole chickens much like you would get from the grocery store , at upwards of 450mph . They proceeded to fire one through the cockpit and 40 something rows of seats. So he and a team were sent to see what went wrong. " You gotta thaw the suckers out first!!" Was the diagnosis.
Heard the same story, but it was testing the windshield of a high speed train. Comments at the end of the report "thaw the bird first". 😄
Hello from the UK where your bird cannon was made. Story about firing the frozen bird is legendary and true
Seen that on Mythbusters.
😂👏
Damn! Imagine building 50 million dollar engines: we need
-One to throw chickens at
-one to throw water into
-one to throw ice at
And if those tests fail we are out 150 million and back to the drawing board.
No wonder why it’s so expensive to fly.
Unless you wanna be a geinea pig
If it passes the tests one engine should be enough for all three. Probably do the chicken last
That opening shot was of a ‘blade off’, wasn’t it? A fan-blade detached with an explosive charge, detonated by remote control.
yes it was.
The thrust reversal is there to minimize the landing gear break stress so that the brakes can last longer, so if a plane doesn’t have a thrust reversal it will have to land at a lower landing speed.
The landing distance required for a plane are calculated without taking thrust reverse into account, so it’s a bonus to have one.
Little known pilot life hacks:
1. If you turn your transponder to 7500, you can actually get a cool free escort from an F-35!
2. ATC bothering you with constant chatter? Simply go to 7600 to relax
3. Is it taxing (haha get it?) to wait for your turn while other planes land? Turn your transponder to 7700 to get free priority landing!
(The FAA hates these simple hacks)
Amazing 👍👍

Rolls Royce are perfect for blending & making chicken soup. You just need a big kitchen to run it.
good video
Sad how people look at cars, planes and other machines and see it as a common thing that people do just because its everywhere, not knowing what engineers go through before getting such results
Be nice to see some death row inmates used fir these tests👍🏻
One key point of the bird strike testing is they only go as far as chickens, if it's heavier than that the engine is dead. This was what happened in the Hudson miracle accident, that goose weight was more than double of a chicken.
Amazing
Birds are not destroying our engines, we are destroying them.😢
True
They test it with dead birds..
These are targeted suicide attacks. They want to monopolize the skies.
Truee
Who cares
Are these tests performed on every engine before they go on planes ? Or just for that specific make and model
I used to watch this at Triplex glass firing chickens out the gun into aircraft windshields.
Why cant they put a wired screen in front of motors?
I watched them doing this at Brooks AFB in San Antonio, Texas.
The test is ok that can save many people!
Where in the engine is the rotating assembly suspended? And how are the bearings that hold the assembly cooled?
fantastic video!! great explanation.... congrats!
The footage at the start is not birdstrike testing. It was a test for fan blade containment. They detonated a small explosive attached to a fan blade at high power to ensure the damage is contained within the fan case.

Why not a anti bird net?
It'll cause suction of the net due to high speed of the engine blades
Reduced fuel efficiency, increased drag, louder cabin noise. And ofc the immense force of the suction would just rip it off the hinges. These engines can propel hundreds of thousands of pounds. So it would rip it right off the bolts / hinges. Hope this helps!
@@Flywithjon and reduced air flow. but the designed to to handle bird strikes. the etops certification for an airliner requires a flight certification that a two engine plane can land safely with only one engine. 4 engine jumbo jets are replaced with 2 engine jumbo jet engines.
@@mrwaterschoot5617 as I stated in my previous comment “increased drag” same thing as less airflow haha. But yes I am familiar with ETOPS certification.

Why suction side nets not using?

*_Former Boeing.... High Bypass Turbofan Engines are remarkable..._*
They are one of the most important parts of any aircraft. They must withstand forces acting on them without failure. They are the single most expensive part on any aircraft. Because of this, Boeing installs the engines at the last stage in Final Assembly. No benefit of putting multi-million dollar engines on until actually needed.
There are a few others things modern Jet Engines have to survive but rarely tested; FOD getting sucked up off runways, baggage carts and containers placed too close to inlets, and unfortunately people who get sucked into an engine.
Testing Jet Engines require very specialized facilities, equipment, and staff. When Boeing buys GE Engines for the Triple Seven, they come to us already tested and certified. Boeing has it's own testing and continuous quality improvement procedures for each aircraft, but we leave Engine Testing to the Engine Manufacturers.
*_The giant GE Engines used on the 777 won't fit inside most homes, they are huge._*
Those GE90-115B engines are just insane. Most people don't realize that a 777 engine is about the same diameter as a 737 fuselage.
@@kz03jd Thanks for comment. Great comparison. I used to say it won't fit inside most houses, it would stick up through attic. But that really has impact. Think how big a 37 fuselage is.
I told people the GE90-115B numbers had meaning, GE = Gigantic Engine, 90 = 9 foot diameter main fan. (I was wrong, it's over 11 feet), 115 = 115,000 pounds of thrust. They can make up to 125,000 now I think.
When I was at Boeing, loved standing next to on install fixture. People look rather small when standing at mouth of that monster engine.
Wasn't there a place making either entire aircraft, or windshields for aircraft, and every bird-strike test they did failed.
After having someone from the FAA come out to help look at their testing systems, it was discovered they were not letting their 'test birds' thaw out... so they were still frozen 😅
Being that stupid should have automatically disqualified them from making aircraft parts
Had to replace a flap one time on a 747, hit bunch of geese on landing blew through the flap giant hole in the airframe u could see the exposed honeycomb material.. craziest bird strike I've ever seen
Trial and error is the most profound reason to explain the success of humanity
Bu uçakların hepsinin bilim adamları dahi gelsin asla başarılı içinde genelinde olamazlar asla yapamazlar başarılı içinde genelinde olamazlar kim olursa olsun başaramazlar yapamazlar
Just a thought and im definitely no engineer and im sure its been thought of but why can't they put a screen over the engines?
imagine showing someone a chicken gun out of context 😂
And yet, bird strikes, hail, debri from runways, mechanical failure, etc. still causes these 15+ million dollar engines to fail. Sometimes catastrophically
Karma
BA Baracus: I ain't gettin in no plane, FOOL!
We've been flying jet airliners for 70 years. You'd have thought birds would have developed protocols to avoid it by now, like no go areas and the like.
Why not fixed styeneles steel mess front in inzeen fan
The first video in fact was not a bird in the engine, it was a blade off test
Created something to fly in the sky but can’t spot chickens 😂
The first scene was not a bird strike test it was a blade off test and it was completely successful.
So they’re going to craft engines capable of resisting damage by birds, rather then crafting some kind of repellent to deter birds from being too close
Why don't you figure that out.
LMFAOOOO no way you are serious. what kind of repellant could you even create to deter birds? its not like mosquitos where you can just spray mosquito repellant. 🤣
I thought jet engines can survive anything ,can't believe a little bird can shut them down ,I assumed they are like a big ass woodchipper
Well. When you factor in the speed the plane is flying at. A small bird hitting the engine at over a hundred miles per hour is a substantial hit.
We need to protect poor chickens 🐥🐣. Can't they use AI to develop protective cage for engines?(so it doesn't affect drag much).
Do you think a bird could survive after being hit at that speed by the "cage for engines" or any other part of the plane for that matter? The issue here is not the bird's safety, but the passenger's.
@@RLMonsterA380 Yes, i do. Planes are mostly at slow speeds when encountering birds, so that many of them can be saved, but also people and 💰.
@@frun Then you don't know much about planes or birds either. A plane takes off and lands at a speed of 180 miles/h or about 280-300 km/h (is what you call a slow speed), no living thing can survive after being hit at that speed.
When humans eat chicken meat,this is a pittance in comparison
You are naive
Back in the day ( Late 70s ) I started working at a place called Allisons and they made jet engines primarily for the military and a lot of it was experimental work . They also made large marine engines . This was back when turbine engines were the hottest big thing . They had their own test facilities but ours were all indoors . The operator had to have an airline taxi license to operate the engines . I remember that they had chicken and pigeon coups on the roof of the test facility and back then they just shot a bird or chicken that were alive out of an air cannon directly into the engines just to see what kind of damage they would inflict on the turbine engines . I sure would have hated to be the guys that had to tear down each engine to assess the damage just so they could build it back to do it all over again .They even shot a few live turkeys in them to see what would happen . After several years animal rights activists complained about cruelty to animals and that was the end of using live animals and they had to buy frozen ones and thaw them out to shoot them into the engines . Ah , the good ole days ! P.S. I remember one time and I don't know what they shot into the engine but it was a TF-41 engine and it completely demolished everything in that room ! Where the guy set to monitor the engine there was a 3 foot thick piece of bullet proof glass and it even cracked it to pieces ! Whatever it was everyone heard it cause it sounded like a bomb .
Former Boeing, I saw an episode of Mythbusters testing the Chicken Gun. They were simulating a Bird Strike on the Front Windshield. Chickens had no problem going through Impact Certified windshields. They found out that it didn't matter if bird was frozen or thawed out. Both caused catastrophic damage well beyond the windshield. Chickens also entered cockpit, then went through plane.
During the early 80's, when a young Naval Aircrewman. I read a report about animal rights folks objecting to the "Chicken Cannon". Sea story, my squadron saw detached duty at Midway...Gooney birds (Layson Albatross) being ubiquitous...it was inevitable some crew would eat one and did. The smallest mech onsite had to go down the intake of a T56 of the #3 engine of a P-3 to clean out the mess. I was glad to be 6'4" and 200lbs. LOL. They douched the engine and later flew back to Barbers Pt. HI.
@@SJR_Media_Group My Skipper told a story one day of his experience while doing field work...a seagul hit the windscreen of his P-3. As he told it... the birds beak imbedded in the thick laminat plastic, while the rest of the bird "carried on". I too saw the Mytbusters episode. Light civil aricraft windscreens evidenlty much less robust than larger aricraft.
@@scottnj2503 One of the chickens on Mythbusters went straight through small plane and came out back or side.
What went in that engine that demolished the entire room was the devil chicken delivering karma. These companies have got so much money they can use anything, maybe they'd use your dog next; live.
All these costly experiments, I came up with a idea to stop bird strikes at low cost & probably 80% more effective. But I ain't sharing it yet. Its so simple.
If airplanes had anti bird net’s it would damage the anti bird net and it (net) would create more damage to the engine/s
Will a SS grill just allowing sufficient air into engine . Should restrict birds and water with louver design..
How to make Mc Nuggets
I'm shocked at how many people keep suggesting mesh, metal screen or even a net to be place in front of the engines! Trust me, if that was a valid solution, it would have been done by now. Jet engines work mainly by sucking in air, and everything is measured and created for that sole purpose: air flow. it NEEDS to intake air without anything getting in the way of that. A screen will block the engine and interfere with the air being sucked in. Even if you don't know how they work and didn't think of that, if the net itself fails then it also will be ingested by the engine and you will end up with the same problem! So its not a solution at all.
Apart from that, many people seem to forget you aren't flying just above the city. Most commercial flights fly around 30,000+ feet above. Birds do not exist anywhere near that, so any type of net would be useless for 98% of the flight. Bird strikes are really only a concern during take off and landing. So it would just provide no use overall.
Why can't the engineers build the special grill cover to protect the engine propeller?
Same thing I was thinking you would think that would be the first idea
Remind me if there is a thing called re-incarnation to NEVER come back as a Chicken …..😏👍😆
But why engineers no cover it 🤔
Would it had made any difference if they had thrown a dead chicken in to the engine turbine ? What was the need to unnecessarily use the life when the dead could had sufficed ????
no the first test was a fan blade test you can see the orange section with the explosives ,not a good start :)
0:00 nope , what you saw was an explosive going off to test the integrity of the case of rolls royse jet engine
Let’s not talk about going to another plane
Let’s stick to 747
What about covering the engine with a wire mesh?Cant that solve the problem of bird strikes??
That was considered decades ago. Having a mesh in front of the intake would not work as the mesh would accumulate ice and then shed it into the engine.
@@k.brucedonnelly4893 Oh thanks

Chicken Watching: "bah-GAWK!!!!?" 😮
Did that test pilot have a black eye?!??
why not have a screen protectorin front of the blades
Imagine that something gets stuck on screen how you think that's gonna work everyone would die plane wouldn't able to fly even engine would over heat and blow up think about it same thing puthing bag in front of your radiator what you think it's gonna happen use your head..
For a moment there, I thought "live" chickens are use on these tests. Lol.
Sorry , I'm not familiar with jet engine, why not have wire mesh in engine suction?
1. If something should hit the mesh at such high speeds, the mesh is guaranteed to break and get sucked into the engine causing total damage. It's safer to have a bird shredded by the fan into little bits than have a wire mesh get sucked in and tangled in the fan.
2. Even if you don't think so, at that speed a wire mesh would create drag .
Love your content on all channels. But the opening shot is not a bird test, it is a blade off test of the Rolls Royce Trent engine. Testing for a situation where a fan blade fails and the fan cowl MUST contain all the shrapnel and havoc released. Thanks and have a cosmic day.
Former Boeing... nice observation. If a Blade comes off, Engine becomes out of balance. If engine fails catastrophically, flying debris needs to be contained within the cowling. That is one spectacular test. Who doesn't like seeing a multi-million dollar Jet Engine blow up when it's not on your own aircraft.
@@SJR_Media_Group And when a failure of the cowling to contain said debris happens, you end up with a incident like Southwest Airlines Flight 1380
@@kz03jd Thanks for comment. Most aircraft work better with 2 engines, hydraulic pressure, and pressurized fuselage. They experienced a catastrophic failure, parts of blown engine went through ballistic resistant Kevlar Blankets and Cowling.
Debris still had enough Kinetic Energy to puncture fuselage. Glad I was not flying on that bird that day. I bet cabin needed 'cleaning' after that.

Better than a human
That is at best debatable
5:35 thrust reversers were deployed before touchdown xD Thats kinda mistake btw )))
I was on flight from Detroit to Dallas. In mid flight we hit an ostrich. The engine stopped and plane shook violently, the food cart hit the ceiling and everyone started to vomit. We made emergency landing in St Louis.
Uhhhhhh..............ostrichs can't fly, do there's zero possibility of your plane hitting am ostrich mid flight.
@@gurpreetsidhu2663 I know, that is what makes this incident even more baffling. Maybe someone else threw it out of another plane or something.
WHY NOT PUT A CONE Shape IN FRONT OF THE ENGINE,the same size to block or Repel anything in front of the Engine...... It can be Done 👍👍
Aero Space Engineers are Wayyyyyy Smarter than I am....😂🤣😂
they should use bigger birds, like storks and herons
why not put a screen to protect a bird from going inside and the screen to form like a sphere or a ball shape screen only to bounce the birds up or on the side ...
A screen would restrict airflow to the engine , airplane engines suck in tons of air in order to produce thrust to fly.
The birds will stick to the screen and the engine will stop
I'm pretty sure 4:00 is a rocket engine. The chilled-in cryogenic lines and expansion loops, I would think, have no place in an turbofan test site.
I'll allow the example of a turbojet test at 4:40 even though it's not specifically an example of a high-altitude test. People should note though that this isn't the same type of engine on the commercial airliners.
After the birds are shredded in the test engine, the remains are immediately taken to KFC for cooking
That's funny how the bird just destroyed the ingine.that made me laugh.9
You must first unthaw the chicken
Wow,after countless travels by air, I feel discouraged and scared to ever fly again after watching these tests methods of the aircraft engines
