Hypersonic Weapons: What YouTube isn'tTelling You! 

I can’t tell you how much I appreciate your videos. There isn’t anywhere else to find such clear-language explanations that can be understood by a non-expert like me. Thanks!

"It is like flying into a blowtorch" 🤣 always the best analogies haha, I'll be using that

Bravo Sir, much appreciated have been awaiting an updated hypersonic lesson

Very educational, and the improvement in the sound quality from the earlier to the later is evident.

Your Italian accent is pure gold amigo - I come back each time just to hear it- like music to my ears 😍

Bravo, your scramjet explanation reminded me of when I visited RAE Farnborough in the late 70s and asked a techhie about an object I noticed and he gave me an enthusiastic explanation of the disc at the end of an aerospike. I think it was still fairly secret then but I had no chance of repeating what he told me then nor really understanding it now😂

Thank you for speaking so clearly as much as I can follow you even on these technical subject. Dictioning has to be awarded with a prize. The authoring for this kind of video is really remarkable and the aim to deliver practical technical implications inferred from complex theorethical disciplines gives a lot to think over keeping me awake.

Dude...bravo 👏👏!!! I've learned so much in this series, and I sincerely appreciate your work!

Your diagrams were just excellent and made a very complex subject much more approachable - ty sir!

Note much of a race when only one side has the big fat juicy targets - Aircraft carriers.

Excellent teaching. Especially like the hand-drawn illustrations.

Yet another engaging topic (YAET). As usual, you make the opaque translucent. Well done!

I love your videos, all the explanations and even some mathematical explanations keep me here.

Excellent cast - thanks for the interesting and straightforward explanations.

Awsome videos!!! i am sick right now, and have watched only your videos the last 2 days. best content on youtube, i just wished you would have some animations when you explain the different engines for example, so it yould be easyer 4 me to understand the compression, mixing with fuel and ingnition part of the engine. So i only can hope that your channel grows much larger so you can afford an animation guy i guess xD LOVE your content!!

I love all your videos as they are so educational and address all my interests. Thank you so much

Really great stuff this...loved all the detail! Thank you so much! 💕💕

Honestly I just put this on while I'm working and can't pay attention to it yet because it sounds nice and relaxing 😂

This channel is so informative!

Great video. Informative and comprehensive, as far as I can discern.

Thank you for this very clear and concise explanation!

5:06 :) :) I love the artist's impression! 😊

Yooo another good vid! Good video idea- indian airforce current projects and how they will perform at the time they release

A visual treat!! Took me back to my school days trying to read RAE Farnborough periodicals Scramjets and Ramjets material from the past school boy days , once again. Simply marvelous presentation so unlike most RU-vid videos. And in other videos Area Rule, aka as Coke bottle design

Thank you for hyper-clarifying that.

Thank you for covering this subject.

Most underrated channel on RU-vid, keep up the good work.🤝

Interesting subject. However, there is a rock I am going to throw at you. 🙂 As long as we are talking about relatively "standard" rifles and pistols, the momentum of the projectile that they are firing is not enough in and of itself to make somebody fall over. That response is the result of the various physiological impacts of whatever the projectile happens to hit and in some cases hydrostatic shock as well. Thus what portion of the target's body is hit is a far more important consideration in determining whether or not the target falls down than the momentum of the projectile considered in isolation.

Thanks for your thorough explanation.

Excellent video

Thank you. That all makes more sense to me now.

I thought their was also an issue with close surface airflow resolved by MHD first thought of by Jean Pierre Petit. His work wasn't taken seriously by the French government at the time but was taken very seriously by... the Russian and US scientific community... His idea, as I understand it, was to megnaticly controle the close layer of air (or plasma at hypersonic speads) making the shock waves desapear all together... There are interesting recent videos of him as specialy the ones around the time Russia came out with it's hypersonic weapons... is that a tale or does it have some truth to it?

Germany started this with the V1 rocket and buzz bomb. Scram jets mixed with solid fuel ad some uranium and here we are.

Thank you so much for your work

Oh man, you just made my whole afternoon! You reeeally researched it "Into mathematics's warts and all"! It's nice that you do not shy away from it.

the blowtorch reference is so on the point. i typically mention the u.s. sprint missile.. or was it spike? i forget. a 1965-1975 era sort of anti ballistic missile interceptor.. it basically was the missile that inspired "missile defender" ... a very old game . but very relevant. the missile only had a flight range of between 30-40 miles if i remember but could pass that distance in a very short span of time, reaching speeds of mach 10 and glow from the friction since it was land launched... was meant to carry a small nuke to get close to incoming ballistic missile warheads and blow them up in the atmosphere.

Amazing. Thank you.

OK. Good to see a specialist doing the video!

What happens to a hypersonic projectile when rifling/spin is introduced?

Sandboxx just did a video about hypersonic weapons as well. Thanks for another great video.

im wondering if parallels exist with the Skchval weapon?( but you'd have to coat the front in spaceshuttle tiles..) but i'm wondering if engine exhaust could be blown out the front to disrupt the bowshock into the shape you wanted?

I still hold out hopes for an overview of scramjets and ramjets.

Thermo-Dynamics, the bain of every physics student, then add Aerodynamics to the mix, and now I have a headache. And... it's just starting. (22:01ish) My Eureka moment on the body shape! Excellent! Thanks!

What about plasma actuators for control?

Thanks!

Big RU-vid channel are just telling people what they want to hear

Great video.

Thank for your job (from France and from my bed)

From the map it looks like you're in or around Stevenage, do you by any chance work for either MBDA or Airbus there?

You are French? You live in Milan? Northern Italy is like heaven. I lived and worked in Turin for a while. Best time of my life.

At 23:10 when you reference near-loss of Columbia on the first Space Shuttle flight, are you referring to the possible damage to the rear body flap (which provided pitch trim at hypersonic speeds IIRC), or something else?

Millennium 7 and Sandboxx need to do a co-lab videos. These guys are experts in all things aero and flight tech.

'What RU-vid isn't telling you' 😂😂😂 ???!!

Very underrated video. I think you should alter the video preview picture and change the titleto "Hypersonic Weapons: Straight facts"

those speeds,,,, theyre in the domain of APDSF rounds?

08:52 Oh dear. You forked up there.

RU-vid is telling me right now. Joking aside, this is a very interesting video.

Beautiful lecture Just like the college days❤❤❤ JAI SIYA RAM MAY BHAGWAAN JI BLESS U FOR enlightening us all on these complex subjects.

How does it transmit and recieve withe the plasm shroud during hyper sonc flight?

Holy crap... an 8 minute introduction! ON RU-vid!

I seems pretty unlikely that sea-skimming hypersonic weapons can be going hypersonic speeds at sea level. Maybe, they have a hypersonic assent/decent but that will have to be high up, telegraphing their existence and giving computers good tracking data. (No, they will not be making radical course changes at that speed.) If they are going fast at sea level and they have something like an ablative re-entry shield on them, they will be the brightest infrared object in the sky after the sun and they should be relatively easy to follow and intercept. BTW, ICBMs are hypersonic missiles and the ability to shoot them down at certain stages has been around for a long time.

23:10 reference? couldn't find any documentation to support that...

so... how efficient is ram jet at its normal operating speeds and how efficient is turbo jet at its maximum speed without afterburner and with afterburner... like general numbers

Is there any way for you to normalise the volume so we don't get deafened by the music whenever your mic levels are quieter in comparison? 🤔

Overcome heat problems with Plasma Magnetic containment FIELDS, like they do in TOKAMAK Fusion reactors ?

Nice that you are stopping short of thermodynamic equations, those could cause PTSD symptoms in me

Technical question: Do you think Kinzhal has a scramjet or ramjet? I would say so because of declared speeds but from the picture I saw it does not looks so... Do you have some technical infos about Kinzhal?

When i see the specs from the Lockheed D-21 Drone, i cant understand why its so difficult to build 50 years later with modern technologies something similar. In year 1969 5500 KM range and 3500 Km\h speed, flown lower than modern hypersonic glide vehicles, it would be today a good ship-killer missile too. Why are they not building such a thing, to catch up in the hypersonic missile race?

the best way to deal with air friction is to repel it. two negative magnetic poles repel each other. it is possible to charge the surrounding air with a high voltage (negative ) electric charge and also charge the hull of the vehicle with the same polarity charge . i think with a microwave system this is possible ,so you actually wind up with your craft creating a boundry layer that is negatively ionised plasma that would sort of be a vacum to the craft moving at high speed. thats my solution. if i can figure it out im pretty sure better people then i have already done it . thats probablly how ufo's move so fast and ofcourse they'd have to use some form of electro magnetic inertial propulsion system. anyway ,there you go

Just a wild thought: I wonder what speeds should be reached for an engine to become viable (if that is even possible) in outer space, given the amazingly low concentration of particles out there. Would it be possible to ram enough of that hydrogen/helium into an engine moving at an unbelievable speed?

For the cost to build one hypersonic missile, you can build hundreds of cheap Alibaba drones and put explosives on them and do just as good a job as a hypersonic missile in taking out targets.

I need to watch this in two parts. Contractor is here cleaning my air ducts and I can’t hear anything.

Thank you so much! Unfortunately the sound is not very good, sometimes difficult to understand..

Imagine going back 200 years and telling people that people in the 2020s use the speed of sound as a unit of measurement, and we argue how many times the speed of sound various objects fly at.

He's very intelligent and learned......................He reminds me of me

Forgot to give you a 👍yesterday, so I am back and rectifying my mistake! And pushing the _YT algo_ at least a tiny bit with a comment. :D

Imagine... an engine that is able to separate the air molecules into their separate elements; pulling hydrogen and oxygen right out of the air and inject them as fuel into their proper fuel distributors in the engine. Literally using the air itself its flying in, as its fuel.🤔🧐🤨 let's do it!!!

I'm really tired of the hypersonic hype going around so I _really_ appreciate this... Rebroadcast? Anthology? Whatever it's called, I appreciate it. Now if RU-vid would go back to allowing us to link to other videos in the comments we could spread the word.

You need to adjust the audio. Some of the music playing during presentation of certain title cards is very loud compared to your voice (e.g. 19:47)

👍👍

The video beside you is an advertisement for precision gel rollerball pens....

This would be an incredible video if you turned the music down and spoke louder. Maybe it's my hearing but I'd say 1/4 of your voice during video got washed out by the music. You did great taking a PHD subject down to where I could almost understand things. Cheers

What's faster, a hypersonic weapon. Or is the DEW system far superior?

But still, hypersonic missiles, even with a scramjet engine, generates a huge infrared signature, which makes them relatively easy to track. And hypersonic missiles don't maneuver very well, which means they pretty much have to fly in more or less a straight line. In short, they are vulnerable to a new generation of laser-based defenses.

I appreciate your videos, but I wish that you would separate the timeline into chapters. I find myself coming back to listen to a specific part again, but it is very difficult to find the part of the video I am looking for.

very very nice but the audio is not the best

I wondered why I found it so hard to follow these very interesting explanations ... until I noticed that the background music is a substantial distraction for me which I find pretty hard to distinguish from the spoken message. For me, the background music is too loud and doesn't add anything at all to such a fascinating lecture.

Comment for the algorithm god. Code for the code throne

What is your opinion of the claims that Iran has build a mach 15 hypersonic crusie missile, that is able to change direction mid air`?

Set Music Volume Down Set Voice Volume Up

😅😅😅 ❤ was the titanic sinkable?

Its unbelievable. Explosive heat gas from explosion run at 9-10 mach for TNT. But scramjet itself fly at half speed of explosion!!!! The burning gasolean in car's cylinder is just a speed of sound 330m/s. It burning speed is far less than air intake of the hypersonic engine.

Now the solution becomes, How Slow Can You Go to Not Be Detected.

as far as i know, its not friction that is creating the heat, its compression.

What RU-vid isnt telling you, but youtube still does....🤫😂

You should do a video on the hypersonic hybrid rocket engine SABRE (Synergistic Air Breathing Rocket Engine) by Reaction Engines Limited (REL) After passing the subsonic shock cone coming into the engine, you do, of course, end up with a hot viscous liquid. This passes through the pre-cooler, which cools the air from 1000°C to -150°C in 0.01 second (10 milliseconds) The heat removed powers the rocket engine compressors and pre-heats the fuel before it's all dumped into the rocket combustion chamber. On its space place concept this tops out at Mach 5+ on atmospheric air before switching to an internal O² tank, taking it up to Mach 25 for orbital flight. Alternatively you can put the pre-cooler in front of a jet engine, allowing conventional jets (well, conventional H² jets 😂) to hit Hypersonic speeds, such as in a fighter jet. The entire project required metal additive construction methods to be invented before it was possible. And it's not a pipe dream either, even the USAF are developing the technology in conjunction with REL.

As always an excellent job. I wonder if the "plasma" systems on the control surfaces of hypersonic vehicles can work? . Greetings .

Even a relatively simplistic missile like "Nirbhay drdo" of Indian armed forces can reach hypersonic speeds mid flight but that doesn't make it hypersonic like the russian "Avangard or Chinese DFZF" truly, because the term hypersonic weapon is very closely related to maneuvering and Scramjet/ramjet tech of a missile, speed is NOT the defining term here, I believe. An Avangard can reach hypersonic speeds like Kinzhal or Nirbhay, but kinzhal or Nirbhay does NOT possess scram/ramjet propulsion and NOT has similar degree of range or maneuvers because it has to take oxidiser and fuel both hence making these more like little ballistic missiles with better maneuvering rather than a hypersonic weapon, which is a whole different league of weapons, IF get the guidance right.

Very hard to hear words above music

Misters. 6 mah rocket hit by one that flying 3 mah speed. Fishing.
