@@zlinedavidthat’s nothing uncommon, even the SU34 have some form of sh1tter. And I’ll be damned if the japanese don’t have aircrafts loos with integrated washlets/bidets.
@@haydengriffiths884That's so like @MrNoipe to say noipe and run, without explanation. But yes, it's reflection vs transduction. In home microwave ovens tho, the cage isn't typically grounded. When an external electrical field is applied to the cage (microwaves), the electrons in the metal move towards the side of the metal that is closest to the source of the transmission, giving it a negative charge, while the remaining unbalanced charge of the nuclei give the other side a positive charge. These induced charges create an opposing electric field that cancels the external electric field throughout the box.
Side note: If you’re ever in Atwater, California, I think they are about to unveil a F-117 at the Castle Air Museum (might have already, they said they were still refurbishing it when I visited last year).
I know this plane is slow, not very maneuverable, and it's design made with early computer modeling, but it still looks like the quintessential "stealth fighter" to me
@@CrackedCandy Lockheed / USAF: "uh, sure, Congress, we could put AMRAAMs in the *ahem* missile bay, yeah" *pray they don't ask about what radar they would get target data from*
Fun fact: it wasn't actually a fighter. It was a ground attack/bomber aircraft but given the F designation to sooth the egos of the fighter pilots they recruited to fly them. Fighter pilots really don't like being told to fly bomber-type planes
Maneuverability doesn't really matter that much. You can't dodge missiles and bullets. Dog fighting hasn't been a thing for decades.(and was;nt feasible to begin witth) you target lock and fire from far beyond the horizon.
Was gonna say this myself. If it's this obvious then there's definitely a reason they didn't choose electric heating. Maybe due to the energy cost of heating Vs a passive chemical solution, but to not address this in the short seems strange. I get it's a short so watch the full video and all that, but to not mention it at all feels wrong
This shouldn't be baffling - using electricity in place of a chemical reaction takes an incredible amount of energy. In some cases, because of materials and conditions in flight, it might take 1 to 2 magnitudes more energy to perform the same deicing. Simple physics and chemistry, and when I say simple, I mean 9th grade high school back 20 years ago sort of level of academia. Convenient doesn't mean efficient.
Also, speed. Turn your defroster on in your car when there’s actual ice buildup. It’s going to take at least 15-20 minutes to even start to see the effect. To make it faster, you’d need an insane amount of electrical power, and this bird is crammed with electronics already. The wiper is quicker, safer and ultimately maintains a better stealth profile.
I used to know an F-15 pilot that was reassigned to fly F-117s. He really did not like flying it. He said compared to the F-15, it was like trying to fly a brick.
You might know my dad then because this is exactly what he did, went from f15s to the 117 and absolutely couldn't stand not being able to play in the air as much anymore. Does the name Madewell ring a bell to you? He was a major at the time he flew them
@@jerryalbus1492 No. This was not a skill issue. He was certified to fly numerous aircraft. For a couple years he was a flight instructor for the OV-10. It was not by his choice. He didn't care for that aircraft either (one of my personal favorites). He couldn't stand flying so slow. He was a typical jet jockey with the need for speed.
If memory serves, that was a small light that was used to light up the refueling area during night time refueling. Notice just aft is the refueling door.
Ah… so that's why they call it a *cockpit* either that or General Aladdeen was on the design team. BTW you'll probably find the correct answer in the comment above this one.
The grid also required the aircraft to be moving at speed to get enough airflow into the engines. In the clip you can see odd shaped doors above the grids those are doors that open on the ground to permit enough airflow and are large enough for engine technicicans to enter when the engines need servicing
This is every jet inlet. This is why you often see sucker doors on earlier jets like the Boeing 707 or jets that require a lot of power when stationary like the Harrier.
@@calvinnickel9995 did the harrier have inlet doors for main engines? I thought it just had the one for its jump jet inlet behind the cockpit Edit: he is correct there are cowling inlet doors on the sides as well as the dual jumpjet door on the top
The way that you present that information sounds weird. The hatch is spring loaded and it's a pretty common feature in aircraft design which prevents sucking up debris from the ground when powering up for takeoffs and such. Aircraft which don't have them have a tendency to suck up ground crew into the intake like this dipshit. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XC1TCXyCqrg.html
Yeah, my F-117 inlet grid recently broke and i had to replace it. Cost me 40 million dollars plus another 300 grand to have it painted. The anti icing fluid only cost me a buck 89 though
You've obviously never bought TKS fluid. Revised from use on light GA aircraft to MIL spec, it probably cost $300+ / gallon, too, even if it was the same stuff.
From what I heard, the F-117 wasn't all that functional either. It required a computer to fly (back when computers were very primitive compared to today's) because it was so unstable. It had a relatively short history, but it paved the way for future aircraft like the B-2, the F-22, and the F-35. It's also very unique because of the fact that stealth technology was still in it's infancy and they didn't know how to make it so stealthy without some weird workarounds.
Don't you dare besmirch the f117. It is nothing like the cybertruck (I know you're comparing the angular shape but still... comparing it to the cybertruck is physically painful)
Fun Fact: The Sukhoi Su-57S uses a very similar method as the F-117 with it's own intakes. Due to the requirement to be able to carry the R-37M long-range air-to-air missile and Kh-69 cruise missile internally, the weapons bays had to be designed pretty large. This meant that unlike on the Su-47, an S-Duct wasn't a viable option. So instead the intakes were positioned under the fuselage apart from each other similar to a Su-27 or YF-23. As the IWB is in the center of the aircraft running down most of the length of the fuselage. Because of that within the intakes, which are made out of composites and coated with RAM on the inner sides, there's a muli-layered structure (I think it was three layers), of different shapes made from RAM to absorb incoming radar waves so that they don't reflect from the compressor assembly. One layer is grid shaped, if I recall correctly, one also was circular with multiple rings inside. It's all in the patents really. So while not exactly the same, the idea behind it is similar although the reasons are different. So it's a feature the two share, another aircraft with this intake design is the RQ-170 stealth drone and the Iranian model based on it.
Fun "fact," this is RU-vid shorts so thank for the word salad but A) Russia doesn't use "patents" and B) if there was anything tactically valuable in what you typed, the Kremlin would be hunting you down like a dog. Truth or fiction we wouldn't know and could not possibly fact check. So thanks for the anecdotes about 1970's technology, you did mention Nighthawk and Sentinel, but yes, everything you described, except for Felon, is _supposed_ to go slow.
@@aardque They do have patents which are submitted to the Federal Institute of Industrial Property. Which is what UAC (of which Sukhoi is a part of) did. With most of the patents having been submitted between 2010 and 2016. The purpose of these patents is to protect the general design and layout they came up with. It doesn't disclose anything specific, none of the Su-57 patents give any actual real world numbers that resemble the fully assembled production variant of which they have 22 in service (meaning with all the RAM, conductive canopy coating, intake structures, RAM coating, you name it). So this information isn't tactically valuable, it just states that they put something in the intake to make it stealthy, nothing surprising for a 5th Generation fighter jet. Aircraft speed doesn't really impact such a design choice, it works regardless of speed. The F-117 and RQ-170 are subsonic for different reasons.
@@DieKawaiiserin more word salad. You go on about "patents" as if they are living breathing things. Russia makes its own laws and respectes no patents and we see the evidence of this in Ukraine. So you can go on about order and "protecting" and all Russians protect is those who wield power, period. 22 airframes after a 14 year development period is _deplorable,_ sir. United States has developed and retired aircraft within that time period. That Felon can't even make itself known at the crime scene known as Ukraine is a testament to its superficiality, despite its cutting edge grids and rubber paint coatings.
@@unfazedmc5734 Curiously, there is quite a volume of "non NATO plane tech," about which to comment that _isn't_ Russian, so for any sort of Russian identifying party to seize ownership of that particular victimhood is itself, particularly Russian. This video was not about Felon, not about Russia and not about NATO. This particular conversation is just that. If you do not wish to participate, don't, but by all means whine to us how Russian technology is so brutally oppressed by "hatred." FFS.
@@drjones762 Actually, jet engines work fine in the rain, so a little bit deicing fluid should not matter much. In a sense, deicing fluid keeps the engines running. After all, if that intake screen freezes up, the plane is going down.
@@drjones762there being something covering the engines makes their performance a lot worse, and liquid could actually help with flight performance as rain basically cools down the engine and makes them perform better in some cases
@@erintyres3609 True...... IDK man, I'm still of the mind that aircraft are all black voodoo magic that shouldn't actually work, but somehow they do..... 🤣🤣
It was also a nightmare to fly and needed a computer just to keep the thing from stalling or shaking itself out of proper alignment, simply because of its weird shape. It was pretty stealthy tho.
It still is. I personally saw it fall off the radar when the stealth was enabled to help train F-16 pilots to detect cruise missiles. Sure, there are more modern, technologically superior radars that could pick it up, but we couldn't see it back on base.
All modern fighters can't be flown without a computer. They are deliberately designed to be extremely unstable so a human isn't sensitive enough and can't react fast enough to control them. The instability makes for lightning fast manoeuvrability. Basically the pilot's inputs tell the computer what they want the aircraft to do, and the computer moves the control surfaces to do it, very fast.
@@catatonicbug7522as far as i know, there are 2 tyoes of radars, high and low freq, high freq cant see these but it has a clear view when it sees anything while low freq can see these aircraft but not give out a clear enough output to lock it, might be some bs though
The glycolic mixture is used for near ceiling altitudes and/or long flights. It has a backup that's like a compressed air system, but it can only be safley used at lower speed and altitude. It's also the opposite of stealthy.
I always find it fascinating to see the many applications glycol has especially since i work in a chemical plant and my unit makes different grades of glycol
@@Mr-Troxthe fact it was only a single one shot down out of numerous flights that pounded serbia is enough to say it was more than dumb luck, dude spent his whole lifetime luck supplies on shooting it down
This is what I was just thinking and looking for a comment about! Surely they'd want to let as much of it through as possible, to then be absorbed by the radar-absorbing material inside, if that's what the whole outside of the plane is covered with anyway?
Round edges reflect it everywhere and make some of it reach the radar, flat surfaces and sharp edges at the right angles reflect it away from the source of those radar waves, which the source needs to pick up some of the waves returning to it to know where and how far the target is, radars are just sonars working with radio waves instead of sound waves
Back when the existence of the F-117 was classified, the Air Force "leaked" the design of the F-19 (the aircraft that was not chosen) and the model companies (Revell, etc.) manufactured and sold those models instead.
Dude!!! Thanks so much for flooding me with MAJOR childhood memories!!!!! I looked it up and totally remember the F 19!!! I also had one or two toys of it.! I loved that thing!!! 😂❤😂
Saw 1 once fly over my house @ like 3am headed twards Chicago. Maybe 500' up. Absolutely silent. Only could see a red belly and green wingtip lights, and a vapor trail.
My father was friends with one of the first Air Force pilots that got to fly this aircraft, before it was ever public. He retired as a Colonel from the Air Force!
The weirdest feature of the F117 has to be its ability to make war time enemies into life long friends despite being shot down by a Yugoslav microwave missile.
Ah yes, the shoot down of the f-117 was the greatest one in a million shot that accidentally created the most effective "stealth doesn't work" propaganda the US could ever have hoped for. Now instead of development of real anti stealth technology, everyone simply belives that stealth does not work, when in reality, it does, and theres not a damn thing a 60 year old radar system in low frequency mode can do to counter it
frankly Im shocked they didnt shoot down the F117 sooner considering they used the same flight path for over a month and fired over 500 missiles at the jet in that time. would have thought they would have got it sooner by pure random chance lol
@coreytaylor5386 that's exactly how they shot it down, pure dumb luck. The first few times the radar ran a pulse, they got nothing back. But they happened to ping it exactly when the bomb bay door was open, which in the case of the F117, could be open for less than a second. Also, Serbians will bang on about it, but they ignore that the F117 had already dropped it's bomb and hit it's target. Also, the pilot was rescued, and F117s continued to fly missions, and they never shot another one down.
@@skyraider87 Serb Here, yup, that's pretty much it 😂 the aircraft was (is?) in our aerospace museum and the headlines in the news was "Sorry, we didn't know it was invisible!" We don't have much, so we might as well celebrate every little victory! 😅
they did not use a radar but spies, the USAF used always the same route to approach Serbia, so they put a spotter outside the airport in Italy and knew exactly when it was going to pass over Serbia. There is no special material against incompetence.
*pilot pulls into full-service 7/11 *tosses keys to attendant "Fillerup on JP-8" *hands attendant $1000 bill "keep the change" "Oh, and be sure to check the wiper fluid"
It's still the most oddly aircraft that actually flew and was in service. The times when it was built and programming for the control is just crazy to think of. It looks like an abstract sculpture more than an object that can actually fly. If I saw it for the first time and got told that this is an airplane that can fly I would I would have said "right... , what do they feed you here?"
If they are so great and advanced, why aren't they still in service today, like the buf B52? This short-lived plane was a huge waste of taxpayers' money.
Because it's stealth capabilities became outdated after 30 years of service and it was replaced by the F-22 Raptor, which, whilst primarily designed for air superiority, could also do ground attack missions like the F-117. A more equivalent to the B52 is the B2 Spirit Bomber, which is still in active service
@dragon12234 Like the 117, the B2 is another example of flushing money down the toilet. 2 billion for ONE B2 @ $160,000 per hour to fly. The good old B52: 84 million (not billion) per aircraft @$86,000 per hour to fly. The numbers don't lie, folks.
@@CJ-nt4cs And it offers capabilities that the B52 just can't do. Sure. The B52 can deliver massive amounts of payload for a relatively low price. But it's slow, and easily detected. Wanna hit a target deep behind enemy lines without them knowing you're coming and minimize the risk of being shot down, you need speed and stealth, unless you are willing to send a full squadron of B52's complete with fighter escorts.
Enemy radar Operator: "we have a radar signature of a windshield wiper at Mach 1.5 coming at us......and it's gone.....wait there it is.......and gone"
They f117 was such an interesting aircraft. We were just figuring out stealth, and just made whatever we understood work. Pivot to an f22, and you get a quick lesson in technology progression and military spending
You know, I didn't realize this stealth bomber design was called the F-117, and now it makes perfect sense why the Longsword fighters in Halo were visually based on these. Master Chief used a Longsword to escap the Halo's destruction in H:1, so when they were designing the appearance of the Longsword they must have said "well this one is the same serial number as Master Chief S-117, so you know we gotta go with it" or something like that. Anyway, cool short!
The thing I like most about this aircraft is that it is impossible to fly manually. Only the flight control computer could make adjustments quickly enough to stabilize the jet. This is one aircraft that actually does NOT want to fly.
Modern Manufacturing methods were not available at time hence squared off cool.asf look it has vs modern-day jets. They had to use polygons etc vs rounded edges. But what a beautiful beast. They even gave it a fighter designation knowing its 100% air to air incapacitated. But the pilots needed to handle it were fighter's. Theyd never volunteer for a bomber fleet. Much like drones. They grounded some the best pilots for drone controllers
Like at the bottom of the cockpit? I believe they are just intended to break up the seam of that panel that would have otherwise beem a straight line. If we're talking about the angled points at the leading edge of the nose, those are for the pitot tube and probes like that
A much better design would have been to use a longer body / thicker wing root, so that the engine could be 'buried' inside the wing itself, and then an all-plastic air-scoop could be mounted onto the top of the wing to funnel the air down into the engine. This way the radar energy goes straight through the polyethylene air scoop with no risk of any radar reflections.
At a time when Euro-spec cars were quirky for having headlight washers and wipers, the U.S. was low-key over here with toothbrushes to keep its grilles breathable and happy. 😅
That's a unique plane with unique features ,.I believe that the aircraft is the first with the bathroom . So extended flights go without diapers , much more civil .
What they should have done besides having a mechanical device was actually having that grill being slightly warmed up during flight it wouldn't have allowed for ice either
The F-117 is a very stealthy aircraft, but was very difficult to fly, until they updated the flight controls to have a computer keep the aircraft stable.
"How do we get rid of the radar signature?" **super advanced radar absorbing metamaterial designed in a super secret lab** "How do we get rid of the ice on the intake?" **windshield wiper**
Just FYI, the F117 is flat and angles because it was computer designed. Computers at the time were not able model the effects of radar waves against curved surfaces.
"Okay, you're good to go - see you in a year, or 12,000 miles. Oh, nearly forgot: we replaced your intake wiper on the starboard side; it was split. That'll be $70,000 + tax"...
And this is why stealths are "hot" when viewed via infrared and there's radar active in the area. It's radiation being captured therefore heating the surface. BUT now the ram paint has 12 sided carbon hollow nanotubes which are incredibly efficient at dissipating all that radiation in turn drastically lowering their infrared signature. Add the reflective coatings also and you have an airframe that'll fade away matching all the background radiation making it incredibly difficult to be detected across all of the spectrum
Stealth airframes arent any hotter than non stealth. Youre at best absorbing 10 percent of em radiation, the vast majority is reflected away. Youd have to be painting the aircraft with a cued search to have a detectable difference in surface temp vs ambient, and no aircraft is being painted in cued search unless its location has already been ascertained. Heat soak from the engines is a far more real world concern, but really only matters if the enemy is relatively close anyways.
Damn that IS wild. I wish there was ONE single source I could go to to learn all of these crazy little details about this and other aircraft. I’ve been passionate about aircraft since I could read yet I’m still learning stuff like this every day.
Are we sure that grid was designed in centimeters? 😂 Good vid man i actually had no clue about the inlet de icing system. I hear they pulled some of em out of storage recently and have been usin em, thats soo kool.
"Hey, we found out the grid freezes over at higher altitudes, any ideas?" "Windshield wiper" "No, not the windshield on the cockpit, the radar reflecting grid in front of the engine inlet." _"Windshield wiper"_
