Imagine if Dorothy Vaughan or Dr. Emeagwali was on it. No offense, but when just one type of people, work on something, they usually end up with something like the Atomic Bomb or Nuclear Power Plants. Nothing good for the Earth.

[@RobP317]

Great video and super interesting, but I really wish they touched on the headwinds (pun most definitely intended) they’ll face trying to limit how loud the sonic booms would be from hypersonic jets. Would love to be proven wrong (or dumb), but I can’t imagine people would be happy with 200 dB booms raining down on them every time one of these jets flies over them.

[@christianhayn8065]

There is actually a NASA Project running that does research around the problem of super sonic booms. Its called X-59. Pretty cool

[@vicherd]

This is an awesome video showing not just the technology but the steps and challenges development hast to go through

Another home run episode John. Thank you for thorough journalism showcasing the pioneering work others are doing.

[@fastonchisanga5194]

John always keeps coming back with extraordinary analysis we missed you John ❤❤

[@Dinolobe376]

Funny how most of your videos start with something i absolutely don’t know anything about, and end up being much more interesting than the subjects I usually watch. The storyteller is at least as important as the story itself !

[@MostlyPennyCat]

I'd love to see you do a video on reaction engines. Alan Bond has been chipping away at zero to hypersonic since the 70s but is really starting to get there.

[@emmanuelm361]

Did they build the hypersonic engine or are they still trying? Love the fact that a lot of this endeavor is talking about the way you need to take to get somewhere instead of how they are going to make this hypersonic work. This shows the world we are living in. Thanks for the share, good work ✌️

[@calimio6]

They seem to. From what I understood the real challenge is to make a commercial version that is cheap and reliable

[@2ded12]

So they have made a ground tested version of there engine that has been tested at hypersonic airflow speeds. The next step is making a airborne engine using lightweight materials

[@RyanSommer]

Nicely done John and team. As I have pitched you in the past, Destinus is a European startup based in Switzerland in the business of ultra high-speed, green air transportation using hydrogen and ramjet engine tech with proprietary afterburners. You might be interested to compare the different paths between the US and EU with respect to hydrogen infrastructure and regulatory approvals. Destinus has a very aggressive time scale for proof of concept.

Not this again....Hypersonic engine sure, but commercial planes with these engines is not going to work if you want to fly at M5

[@BotanistOnDuna]

The Concorde flew passengers at mach 2 on January 21, 1976 for the first time. It has been 48 years since then. I don't get why they wouldn't work flying passengers.

[@abdullahaliyuw]

Incredible information! Incredible innovation!

[@Iamwolf134]

It's that kind of hypersonic plane taking flight for the first time, for all its expense, that will truly make the world that much smaller.

[@AnimeFan-ot7bu]

The thing is they need to make the plane cheaper so the tickets are low enough that everyone can fly supersonic

[@univera1111]

For the first time combination of inventors and inovators that really want to make practical change and profit not just the money.

[@deucerichards502]

You don't really see flight trajectory mentioned anywhere, likely because it's probably, questionably, the achilles heel of the entire project. With that air breathing engine, and that speed, they're not going to be able to get high enough to get above the Tom Cruise Darkstar problem. Not without taking significant amounts of heat damage. That's a massive logistics problem for commercial airline services turnaround times.

[@MadisLiias]

What about fuel usage for same distance compared to an ordinary passenger plane?

[@NonEuclideanTacoCannon]

Adiabatic heating. That's what will kill this project. A big breakthrough is needed to build a hypersonic vehicle that flies more than once. My bet is transpiration cooling. Otherwise what are they going to do? Spray it with a fresh coat of ablative cooling paint before every flight? Even transpiration cooling will add significant weight and complexity. If they were using cryogenic fuel, they could circulate that through the leading edges I suppose.

[@jonathanvanwersch8500]

What did Concorde do about this issue?

[@NonEuclideanTacoCannon]

@@jonathanvanwersch8500 they didn't, Concorde wasn't a hypersonic aircraft.

[@alexb16]

excellent! to bad the video didn't mention the "Leduc 022" or the "Nord 1500 Griffon". two french planes that flew with hybride ramjet propulsion in the 50's ;)

[@bigbeardtrader9740]

What about the scary sonic boom? Wasn't that the main problem of Concord??

[@olivermoreno9433]

Very inspiring to see fellow Yellow Jacket PhDs doing incredible work!

[@utterlove]

22:15 in before we hear them say the actual goal of the company. They're trying to be a defence contractor, but promote some lofty goals to revolutionize civilian air travel to guarantee they get their slice of the US military budget. We'll see hypersonic cruise missiles long before you ever get to fly from LA to TYO in three hours.

[@essamzee594]

[@pedrosura]

Hypersonic Air Force One… On one of the Episodes of the “Six Million Dollar Man” TV series, Oscar Goldman travelled in an F104 Starfighter. There could be a hypersonic vehicle to get a President, Cabinet member or General quickly somewhere. Good idea

[@pangrac1]

Selling the idea of need of pocket Concord for 20 ppl in the era of facetime meetings around the globe sounds bit obsolete to me. Especially in the post pandemics era. Yep we need such propulsion but I see most of it use in the military area.

[@rsperez2010]

At 11:54, this video states that transitioning from a turbo jet engine at low speed to a ram jet engine at high speed has never been done in flight. I thought the SR 71 did that routinely starting in the 1960s?

[@zaprowsdower9471]

Is this an Aerospike engine? Is the vehicle a SSTO, is that its ultimate goal? What is the motor's Specific Impulse (I^sp)? I don't recall them saying.

The video forgot to mention that Russia has Two Hypersonic attack Missiles and is the only country with Air defense that can take out Hypersonic Missiles. Russia is in a race to build Hypersonic Planes and drones at the moment. I can't understand why hermius isn't getting funding from the start?

[@unibeastbeats]

I understand when tech people say "Let's break things and move fast", but when engineers say "We basically jump off the cliff and build a plane while falling" it is not encouraging at all.

[@benmcreynolds8581]

This seems way more of a military use thing. Rather than a commercial travel use thing? Who knows? Maybe they will find a way to change the way things function? Will see..

[@ryanaiden]

Looks like a pod racer engine xD

[@TheVinceVoice]

Wonder how efficient this will be and what environmental impact this would have if we used these to speed up the world 5x... or whether they've thought of how to actually make this work in an environmentally friendly manner. Otherwise it's probably just more the 0.1% burning more to do things faster for themselves.

[@hey_you]

I have not watched the whole video, but I was thinking the same thing. Flights are already crazy expensive, most of the time, for any halfway decent airline. On top of this, all we hear in the news cycle, is about how we have to stop using fossil fuels. I have a feeling that this tech will end up being used by the wealthy, like you said.

[@OmniUni]

The good news with something like this is that because of the way that ramjet technology works, once it's up to speed (roughly, over mach 3), it's actually more efficient than a turbojet. Although you would make a lot more individual flights with a small craft like this as opposed to bringing an entire group of people at once, the aircraft would spend a much greater percentage of time in a higher efficiency mode. So overall, you're saving fuel and burning it cleaner as well as saving time. Honestly, if this works, it will revolutionize international travel beyond what this video even implies.

*HERMEUS & JETZERO ARE ABOUT TO PROVIDE THE GREATEST LEAP IN AIRCRAFT TECHNOLOGY THAT WE'VE EVER SEEN! 2030 IS WHEN THAT NEW GENERATION STARTS!*

[@prateekbhatt25]

It's great to see this hypersonic technology, but I think efficiency and safety will be affected. It's better to build a commercial aircraft that travels at 1500km/hr, with more efficiency than today, that's almost double the speed of what today's aircrafts fly.

[@ulrichraymond8372]

I don't think mach 5 passenger travel is economically feasible. Military may be more Interested but satellites do a good job compared to planes so it would not justify its use.
