Ramjets and Scramjets Explained - Mach 14

internal jet air flow with a compressor when beyond Mach 8

some comments on this video are filtered out by YouTube ( Google ) so sorry if you see that. It's not me.. so please comment and I'll do what I can to post the comment. I'd guess that Google classes some comments as potentially terrorist since the scramjet is the next wave of tech to be used on American drones. This would of course make them mostly invisible to radar and so fast they couldn't be stopped

Terrific explanation for us non engineers.
Well explained and presented.

[TheLeontheking]

interesting that "normal" jet-engines are actually the most complicated design of the three!

[MrDeville]

I could listen to this bloke talk all day, reminds of the science VHS tapes in high school.

[dennishawn]

What interested me the most was the fact that while Queensland University has done so much work on this concept. The actual state of scramjet research is buried in the depths of "Classified" information probably in Russia and the United States.

Good lecture. I’ve worked over 40 years for the US Department of defense in the acquisition of weapon systems and one rule in certain, stealth is cheaper than speed

[leokimvideo]

Australia has a long history of amazing inventions mysteriously being bought out and never appearing again. Remember Metal Storm? Where is is now?

[doodleydoo]

you really should look at the Sr-71 engine diagrams, the are normal turbine jet engines but with 6 bypass tubes moving air from the leading cone to the exhaust making them ramjets. As well as being able to keep the perfect pressure/speed mix by varying the cone distance.

As long as the projectile course of a rocket is in an atmosphere, the use of alternate methods of propulsion for a rocket is a possible option because the use of jet, ram, and scramjet technology increases the potential to reduce the material requirements needed to accomplish whatever task you are shooting for when utilizing a rocket.

i've watched this so many times; its just brilliantly easy the way he explains it, pity this guy wasn't my lecturer in college :- (

[richardgithens]

Excellent presentation. He made it easy to understand. It will be challenging for the material engineers to come up with materials to handle the extreme heat issues.

I found the scramjet section very interesting, thanks for explaining it so clearly, im very interested in this kind of engineering as we are seeing it more and more each day!

[TheRojo]

Notice that it's actually dynamic pressure that counts for thrust, not static pressure. So it pays to take advantage of synergetic motion of the exhaust gases, and the mechanics of supersonic fluid flow.

[MogotsiT]

Excellent and clear explanations. Such a complicated concept explained this easy is amazing. Thank You

[softskillsguy]

Excellent video. May I suggest that when talking about speed in general you also keep in mind that most "proper" Engineers who work in an International environment find the use of the French "MKS" or Meters, Kilograms, Seconds to be an abomination. Especially the use of Kilometres when it comes to speed. I suggest "miles per hour" is far more widely used and by some of us less hated as a cause of confusion and errors. The quality of your video makes it worthy of an International audience beyond the narrow (but very lovely) confines of Queensland, Australia. Party on.

[TwentyThrill]

Wish all the lessons I've had in my life were taught this way

[DarrenStarr]

That was a really, really good video. So well explained.

[mlccrl]

Sintesi: ottima spiegazione della differenza tra turbojet e autoreattore in pochi minuti. Chiari i concetti espressi con linguaggio appropriato. Livello accademico.

[Shilo-fcxm]

I know very little about jet engines period and came here as a novice.
Fully understood your description so within that paradigm, well done.
Aussie Aussie Aussie!

The Maverick Package is awesome in the MSFS! Which brought me here.
