For anyone wondering: the term Quarterhorse comes from the breed of horse specifically bred to race a quarter mile. They have explosive speed, and are actually faster in the quarter mile sprint than the more well-known distance running Thoroughbred, famous for their mile+ races like the Kentucky Derby. Naming something after a Quarterhorse implies it can achieve extreme speed, extremely quickly. I’m a horse nerd, I had to say it. Where he got Quarterhouse, I know not. But it made me want a steak.

The SR71 was made in the 60s but it still looks like it's from the future.

[@scottbrady6240]

DOES IT THOUGH?

[@rtqii]

Ben Rich wrote an excellent book about the Skunkworks and covered the SR-71 development. He was in charge of thermodynamics and that design was a major headache for him to solve, and they never got it 100%... The plane got so hot the airframe expanded and the cold fuel tanks did not, it had to use specialized fuel, and the flexible seals degraded and the tanks frequently leaked fuel during and after flights. The cockpit air conditioning had to blow at -40F to keep the cabin temperature at 80 degrees, you could freeze skin holding it next to a cockpit vent. Then they dumped the unstart problem on him because he designed the adjustable cone intakes on the engines and when parameters shifted the shock wave a few degrees it caused an instant compressor stall that slammed the plane around with such force it threatened to knock the pilots unconscious. They installed sensors and a computer to automatically correct the cone position when an unstart was detected.

[@WarblesOnALot]

G'day, Probably because, back in the 1960s, most of the people who designed and built the SR-71 THOUGHT That Humanity had a High-Technology Future ahead of it. Anthropogenic Global Warming was well understood, by Climate Scientists and Meteorologists...; but the Techno-Heads working for the Military Industrial Complex were either uninformed, Wilfully Ignorant, Or living in Denial. So they competed to design Single-seat Hairygoplanes which could Fart more CO-2 in less time, while travelling further, faster ; than anything ever built by People driven by their own Overcompensated Inferiority Complexes, projecting all their Self-Hatred and Loathings outwards, onto the "Designated Enemy" In some Ethnocentric Out-Group, Who "must" be defended against, and who "Needs" to be Beaten unto Submission. And, Thus... We TRASHED The EARTH. Very Very VERY Cleverly... & Powerfully, At great expense. Because Worriers are Fearful by "Profession". Such is life, Have a good one..... Stay safe. ;-p Ciao !

HIFIRE and SCIFIRE helped develop USA HACAM and HAWC scramjet missiles, they are joint USA, Australia hypersonic tests. Australian company will test fly a scramjet powered drone in 300 days and probably beat this Hermeus. but Alex Hollings will not do anything on it. Australian company won a USA HYCAT DUI contract to build USA hypersonic vehicles and won it over 63 other companies including this Hermeus. Guys who own the company helped USA in HIFIRE.. guy who designed scramjet worked at NASA and all he did was design scramjets. Aussies invented the oval designed inturned scramjet design. problem they found in X43 was it was rectangular and had heating problems..

It is above Mach 5, where it must switch to scramjet. What this means is, that they must design a hybrid engine from three different concepts into one. Plus a 4th engine type, a rocket, to return from orbit.

[@everettputerbaugh3996]

The Pratt & Whitney J-58 in the SR-71 was a combined-cycle engine. The JP-7 fuel was formulated to NOT ignite easily partly because of the high temperature inside the tanks but also that it could be used as hydraulic fluid (to keep the hydraulic system cool enough to work) and as coolant for the skin. Pilots claimed that there was still throttle left when flying at the official speed limit of Mach 3.2. Bits of the titanium skin would be getting soft at Mach 3.4. Not bad for 1958 tech.

[@michaelwilson6358]

In modern terms, the J-58 blurs the line between an 'adaptive cycle engine', which is a turbofan that can vary its core/bypass flow ratio, and a 'combined cycle engine', which has a complete turbojet/turbofan and ram/scramjet (or even rocket) sharing the same inlet and exhaust nozzle. The bypass ducts on the J-58 only started after the 4th compressor stage, and only carried 25% of the airflow. Unlike a true combined cycle engine, the turbomachinery was always active and fuelled, not bypassed and shut down. However unlike any current adaptive cycle engine, at cruise all the useful compression came from the inlet and all the useful thrust came from the afterburner section - the compressor and turbine needed to be active to make the airflow work (and run the ancilleries), but thrust generation was similar to a ramjet. The J-58 was an amazing bit of engineering and often misunderstood - there seems to be a lot of misinformation about how it works.

​@SortaProfessional89 I think you'd be surprised. Hypersonic tech got shelved during the cold war. On paper from what I've seen, is doable. We've had the tech for 40 years now. But due to various politics, corruption, and lack of need it all got shelved. So it's the relearning of already completed concepts

[@pantern2]

If I recall correctly, one of the main reasons work on supersonic commercial aircraft pretty much stopped was because the Concorde was so bloody loud that the number of routes it was allowed on was very limited. If you want a hypersonic craft that will be allowed to fly over any settled ground it will also need to make it be able to fly that fast without a sonic boom. I know NASA has a test craft for that, at least for supersonic speeds, but I haven't heard anything about how successful it is.

So that wasn’t the SR-71 in the opening. That was the A-12. Only reason I know, is because you showed footage from the USS Alabama battleship park. My favorite place in my hometown.

[@keithpennock]

Not the A-12, the Lockheed YF-12 the Interceptor variant of the SR-71 that had both guns & carried Falcon missiles.

[@herethererainbows]

This is really awesome to get an update on this company and all I remember seeing a video explaining the engine a while ago. I hope in 200 or so days from now there is another update

I appreciate this video so much! I feel like I get 2 great cups of coffee out of my harrio grinder and aero press at the office with a local dark roast. I know dark roasts aren't the preference for coffee enthusiasts but your nose knows you know?

[@Frazec_Atsjenkov]

A lot of excitement for a prototype that hasn't flown yet...

[@rodepet]

Reasons I '👍' a video: Keeping track of what I have already watched. You know when you listen too Simon and you don't know if you've seen this vid or the same subject on another channel 🤣

[@_Yep_Yep_]

Blackbird, according to this channel, was mach 3.5-3.7 with plenty of engine left. Keeping the airframe intact was the reason they never pushed the SR71 engines to max. Hopefully, Quarterhorse has the airframe solved with a robustly reusable platform. I would hazard that the engine is already in the bank.

[@tacwolf4962]

Super interesting stuff! Thank you for the video!

[@yggdrasil9039]

Hopefully they can successfully do a Long Range commercial version of this with the Halcyon. Sydney-London and Sydney-New York in a few hours would be awesome.

[@ronaldviens7862]

Can you imagine how frickin hot that bird will get doing hypersonic in the atmosphere? Even the upper ionosphere has enough air to burn it up.

[@tonyrich7011]

Lockheed Super Constellation engined with the Pratt and Whitney R4360R59B. Good fuel mileage and comfortable travel!

Always well researched, informative and excellently narrated

[@unkleturpis9253]

I've been arguing for wingman drones for decades now. Glad they're finally considering it.

[@bobthegoat7090]

Imagine this: you are an airforce pilot flying a dangerous reconnaissance mission into Russia. Then suddenly, alarms beep as you realise that a missile has a lock on your aircraft, and you will be dead in a minute. You decide to do a very advanced maneuver to try to get away alive. You push the throttle up to 100%, and you accelerate up to mach 6 where the missile is left in the dust. I know many SAMs can reach speeds up to 9 mach like the SAM fired from the S-500, but there are still a lot of missiles a mach 6 aircraft could outrun, and maybe even outmaneuver hypersonic missiles.

[@coconutsmarties]

*"Imagine something that can fly like an airplane... but do it while going BLOODY quickly!"* Not where I thought that was going

[@elliotsmith9812]

Take a second to think about this. In order to go forward at Mach 5, how fast does the exhaust of the engine have to be? It has to be faster by the amount of drag the ship experiences at Mach 5. But it doesn't just have to be faster. The exhaust is low density plasma. The exhaust has to have more momentum then the vehicle is loosing from drag. This is actually insane.

[@garagatza]

Been following this subject a bit! pretty cool!

If Simon has to go retro and do a Business Blaze episode on this (if so, maybe in ten years or so), I can only imagine what he’ll have for material!!

Warfare is about economics. Throwing multi-million dollar systems at what is in essence a fairly low tech problem is unlikely to pan out in the long run.

[@andrewharpin6749]

The J58 used in the A-12 and subsequently SR-71 is a combined cycle engine.

[@surferdude4487]

We've had super-sonic flight since Chuck Yager flew the Bell X1. But, to this day, nobody has been able to make super-sonic passenger flights make economic sense. The SST was always losing money and that was the most successful of all attempts to fly passengers faster than sound.

[@everypitchcounts4875]

DarkHorse. Their Chimera engine is what everyone else is looking into

[@randybentley2633]

Their eventual passenger craft, the Halcyon, appears to take design cues from North American Aviation's XB-70.

[@jamesleate]

Quarter Horse,, Quarter House, completely interchangeable eh Simon?

[@TheNewOption]

dude, all these comments are proving 100% that mispronouncing things to ragebait people into commenting works extremely well for engagiement.

[@jamesleate]

@@TheNewOption No, it proves that if you want to become very wealthy using KZbin, you still need to be professional rather than lazy. It also brings out lily-livered apologists as I'm sure you know better than most.

Woah, t-shirt!? Simon used to be our boy in the blaze!

[@thomasfaucher2756]

As an old Tom Clancy fan, I just can't help but think that if we are hearing about it, it already exists. So too does the next generation.

[@extragoogleaccount6061]

But that’s not really the way scientific advancement works. Truly new tech comes from universities and other research level laboratories, then picked up by private companies to make the tech viable outside of a lab setting, and then goes on to be included in military projects.

[@steveschweitzer4181]

The Space Shuttle was suppose to be low maintenance. Call BS on this claim. The “engine” was actually the “easy” part. Materials for the aircraft and fuel are going to be very challenging. See what made the sr71 so damn expensive to fly.

[@shawnrhode]

Phase 1 and 2 of the Chimera sound exactly like the engine used in the SR-71. Basically, the SR-71 converts to a pseudo Ramjet at above MACH 2 or so until it tops out at MACH ??. This is done by inlet control using the inlet cone and variable geometry vanes. Getting this wrong during early testing is how they lost at least one plane with one survival and one death as a result (the story for this is insane as the plane just came apart around the pilots). There are two primary issues with air breathing engines and super/hyper sonic flight. The first is dealing with the shockwave itself. If not dealt with, this can cause cavitation at the inlet, leading to engine starvation and stalling. This one is already pretty much understood and handled. The second is dealing with super/hypersonic airflow through the engine itself. Most early design scramjets used a open/close model. The engine has two doors, one in the front and one in the rear. The rear door is closed while the front is opened. This allows air to enter the combustion chamber and compress (due to the internal engine geometry). When the parameters are right, the front door is closed, fuel is sprayed into the combustion chamber then ignited. At this point, the rear door is opened. This allows the combustion wavefront to expand out the rear of the engine, providing thrust. Early observations of this type of scramjet often referred to it as "donuts on a rope". Basically, the craft produces pulsed bursts of combustion with a connecting vapor contrail connecting the puffs of exhaust. There are newer versions of engine geometry that do away with this model since the mechanical requirements are complicated and failure is always a concern. Usually, the resulting burn pattern is similar because the geometry still creates a similar behavior, just without mechanical doors involved. Neither ramjets nor scramjets work at low speed because there either isn't any air (starting from a standstill to taxi) or too little air being pushed in to create thrust.

One or 2 rooms, quarter house. Hermeus’s proof of concept aircraft, Quarterhorse.

[@Medley3000]

If there's one thing we know for sure, it's that development cost predictions are ALWAYS way too low. If the real costs were given, many projects would be dead from the outset. It will be no different here and in reality will cost billions again.

[@splitsecondmagician]

The Loyal Wingman project..... Ace Combat 7 vibes there.

[@steampoweredgamer1080]

Very interesting article Simon but I think we all want to know, does it have cup holders?

[@aaronfredrickson9538]

Yes. We must know !!! Most important feature in any vehicle

[@zaco-km3su]

If these guys succeed with the Quarterhorse they will end up becoming like Lockheed Martin or Northrop Grumman or Boeing. Darkhorse will make them a legend. Halcyon most likely is a dream though. Let's see something hypersonic first before we talk about scramjets and speeds above Mach 6.

[@AjollynerdVO]

Oh. My. Glob. Simon saying “quarter house” is pushing my blood pressure to unhealthy levels.

[@Johnnybananass-_]

its like the Topgun activity module in MSFS 2022. take off under jet, turn on scram get to that speed and hit the go button,

[@mlykjy123]

This is not 60yrs behind. Yet a measure of minutes of development

[@ericwarmath1091]

No mention of the impact of friction on high speed flight.

[@ApothecaryTerry]

Napkin to airplane in 204 days. Dude needs some origami practice, I can make a paper plane in 17 seconds, which is a million times quicker. Edit: On a more serious note, love a bit of referencing between good channels on KZbin. Anyone referencing Sandboxx (and vice versa) is doing something right.

Looks like the PAN AM plane from 2001. That classic Bone that turns into a space station with the plane approaching. Looks identical to

[@ruukiiee]

A hypersonic reusable aircraft? That would be incredible... tech which would change everything, at least militarily, that's for sure. Take off like a plane, go hypersonic, land and do it again and again. Some would "kill" to get a hold of that kind of tech.
