What Is A Scramjet Engine?

A scramjet engine is a supersonic-combustion engine that ditches the compressor and turbine of a typical jet engine and can attain speeds greater than Mach 5!
A few months ago, India’s DRDO (Defense Research and Development Organization) made the news for successfully conducting the maiden flight test of its unmanned scramjet demonstration aircraft for hypersonic speed flight. Yes, that’s a mouthful. The demonstration aircraft was officially called the ‘Hypersonic Technology Demonstrator Vehicle (HSTDV)’. The aircraft was designed to achieve speeds greater than Mach 6. To put that into perspective, a passenger aircraft travels at a speed significantly below Mach 1.
Speeds of Mach 6 or higher are achieved by using scramjet technology. Scramjet technology is extremely difficult to develop and, before India, only three other nations (USA, Russia, and China) have been successful in developing such a technology.

The visual component of this video is confusing and non-sequitur.

[@mcclendonrealestatemcclend2090]

They don't really want us to know how easy they work.

[@t29heavy67]

I thought they were pretty helpful to illustrate how it works

[@lluzeliv]

I ended up building a time machine by accident

[@Tommy1977777]

It deals primarily with airflow.

[@dcolb121]

I agree, Nomad. The pictures are uncoordinated.

[@Eagle2b15]

Good explanation! Use the visuals to compliment the explanation rather than just bounce around in a picture slide show.

[@iaa13]

Totally random images that mislead you more than helping you understand

[@ursulajones5349]

My husband Roger worked at NASA LaRC as a graphic designer in the Hypersonic Air Breathing Propulsion Lab for 20 years! The slide at 4:17 (drawn by someone else) changes at 4:22 into the exact one he drew while he was working there. In fact it's on his phone and in his portfolio. His is more detailed and has a scramjet type aircraft. That is so cool they briefly included his!

[@FEARYOYOYO]

That one is the key slide to understanding this. imo. Cool husband.

[@dwhughes1975]

Respectful feedback on your video design: I find those bouncing sliding transitions really visually disruptive and distracting, in a way that makes it significantly harder to learn from the video.

[@dcolb121]

The images shown don't seem to match what the narrator is talking about as they appear randomly.

[@B1rdTheW0rd]

Great explanation guys.

[@stevedifrancesco9387]

This was super helpful in learning about sram jet and ram jat engines-Great Job

Pov: You are interested in Scram Jet Engines after watching Top Gun: Maverick.

[@vantablacklogicthoughts5186]

[@Mr_Roomba_]

you talking about the DarkStar

[@alexkovachev6765]

Scramjets do not go below supersonic. Just a major thing to edit. Internal inlet flow reduced, yes, however reduction of the airflow Mach number still indicates supersonic flow. At exhaust during supersonic combustion, the airflow will reach ever hypersonic speed, though usually mach 4-6 at the exit. Mach~9.5 is max reached. Theoretical Mach~18.

[@andrewpurvis8961]

Very cool, but pretty sure the only realistic use for it is missiles. Less parts and lighter

[@captainq-ball9422]

So… it’s really fast. That’s what I get from this.

[@jareddimatulac2282]

I don't know why i love watching these kind of videos but still having a hard time catching up to our thermodynamics sub

[@gilberthvaldez2476]

😮 WOW

[@neiljohnson7914]

Scramjets need a lot of air to work. But there is no air in Space. So in Space you can't scram!

[@MentalParadox]

Or at least no one can hear you scram... (I assume that was the joke)

[@neiljohnson7914]

@@MentalParadox yes, I forgot the "no one can hear you" part

[@madmanatsea]

So where do the Astronauts get their Air? Maybe you need to figure that one out?

[@ceoof601]

@@madmanatsea 🤦🤦

[@devmmmdoesstuff6429]

@@madmanatsea they bring the air they need in highly pressurized containers, all spaces the astronauts live in must also be pressurized so they don't die.

[@wasteoftime5482]

I got one about all the way made I just got to figure out how to get up to speed that the hard part for me

[@madmanatsea]

Thanks for the Video…….An engineer would take 5 months to try to Learn what you Presented in 5 minutes. Thanks again.

[@NamikazeMinato-pp1jl]

Saya sedang dan sering kali memikirkan plane ysng bisa berubah warna saat di udara

[@ragezombie1232]

Question: Could a scramjet be switched to use a liquid oxidizer mid flight?

[@voanirges]

yes

[@NamikazeMinato-pp1jl]

Saya pikir menjadi jet siluman tidak harus cepat lajunya

[@Fuzato15]

Is there any peacefull aplication of such engines? Or they can be only used in missiles and fighter jets?

[@t29heavy67]

What do you mean yet???

[@blankcircle]

The visuals are very confusing while trying to listen to the explanation

[@t29heavy67]

They helped me alot

[@heartwoodsolutions]

Did chatgpt write this video?

[@tort.2251]

AI narrator knocks down credibility a few pegs

[@mars27970]

I like Ramjets as the SR 71 has them! My fav plane.

[@wasteoftime5482]

everything is affected in the same way we all go through the same turbulence path of least resistance

[@jeffbanks9955]

supersonic speeds, starting at mach 3? supersonic speeds start at mach1 lol

[@keithtam8859]

how do engineer and scientists come up with these design as these phenomenons happen so fast and therefore can hardly be observed... so just maths model??

[@jayfosm3]

yes equations and modeling which is made from equations. its just physics brah

[@marcelk8523]

Comptional Fluid Dynamics simulations can be found really usefull

[@kribe3401]

Too fast. Impossible to follow your video. Slower, please.

[@aliencat8556]

A lot of images that don't match the audio

[@MBessems]

Fuck I feel old for saying this, but can we please get human voices back?! I realy wanted to know about this scram engine but I can't stand this emotionless psychopath voiceover anymore

[@neils2357]

Couldn't watch this, photos are garbage!

[@LeeFall]

Thanks MR AI voice... Honestly its 2022 dude. Just talk

[@elouanp4588]

Scramjet engine have been discover by à French ingeneer, René Leduc, in 1930 :) Called the "statoréacteur"

[@ricky445]

This video has to be one of the worst compiled videos I’ve ever watched. Congratulations.
