Looks like a polished version of the D-21 drone developed for the SR-71

The depressing thing about this is they're learning how to do pre-compressor water/methanol injection with this. That is to say they're having to relearn what P&W did with the same engine for RASCAL over two decades ago. All this research when, "back in the day", McDonnell Douglas and GE were able to add this to an early F-4 to go after the Skyburner record almost as an afterthought.

Looks like the Hermeus' tech isn't as elaborate as that developed for RASCAL. (P&W actually did the work but then DARPA cancelled the program.)

That’s the thing I notice with companies like this now days, they’re spending all this money to do and find out things that the big dogs did back in the 70s

[-]

garygigabytes@reddit

True they tried all different kinds of things. But they didn't find it feasible back then with their current tech. Nowadays things are very different and can approach these problems in a different way that wasn't possible before.

[-]

m-in@reddit

The big dogs don't share.

[-]

STAXOBILLS@reddit

They really don’t at all and it’s SO FUCKING ANNOYING. And what they do share is IMPOSSIBLE to get, like great I’m glad Grumman has a massive archive and they proudly boast about it on their website but why the FUCK is it so damn hard to contact them, all I want is to get a clear answer for what the tomcats landing gear struts are made of via a material spec sheet, why the fuck is it so hard to find dawg😭

The intellectual property that those companies own is a massively valuable thing that no one gives away for free. To get that info you likely need to write a contract with them and sign NDAs and pay millions of dollars.

Some legacy companies the test date and info they have on manufacturing and processes is the most valuable thing that they own.

ziper1221@reddit

Yeah. I found a few old papers about hydrofoils by Grumman or a long-defunct company called HYDRONAUTICS; and the works cited page will have 100 references, half of which have titles which exactly describe what I'm working on, 97 of which are unavailable on the internet. I've actually had decent luck reaching out to those which were published by organizations which still exist, but that is rare.

Could be worse. When Fairchild-Republic closed it's doors they gathered up all the hard copy documentation they had and threw it out. The only stuff that was saved was that which individual employees squirreled away.

[-]

N3onknight@reddit

Because then they'd ask you back why would you want to know ? Who are you ? Are you connected in any way shape or form to iran ? Bruh, We have you on thermals, your pc is overheating.

[-]

CardOk755@reddit

Ask the Iranians?

[-]

ziper1221@reddit

If the research was paid for by DARPA shouldn't it be in some government archive somewhere?

[-]

KommandoKazumi@reddit

To be fair its likely P&W never bothered to share their methods while Boeing treats their aquired tech (from McDD) like forbidden scrolls locked away in some crypt buried under the bodies of whistle blowers and tax collectors.

[-]

rcbif@reddit

This gives me Planet Express (ship from Futurama) vibes.

[-]

Pmyers225@reddit

Hold up, thats a modern prototype!?... That's straight 50-60's styling... That's extra cool now

[-]

Annual-Advisor-7916@reddit

The design goal of just speed too! 50s engineers probably assumed that 20 years later they'd fly missile shaped aircraft at mach 5 into a soviet bomber formations and fire an unguided nuclear missile on them.

Good lord stop i can only get so erect

[-]

Pmyers225@reddit

Look at the English Electric Lighting for an Interceptor example

[-]

ziper1221@reddit

the Sears-Haack body is timeless

[-]

Empty-Meringue-2386@reddit

Yes it looks like the X-10 of the 1950s.

[-]

Virtual_Area8230@reddit

Have you seen an X-10? More like an F-100.

X-10:

[-]

Tasty-Fox9030@reddit

What is that, a prototype Navajo or something like that?

[-]

Virtual_Area8230@reddit

The X-10 was a flight test vehicle for developing flight controls for the Navajo missile.

[-]

LurpyGeek@reddit

I feel like this picture is kinda dirty.

[-]

Tasty-Fox9030@reddit

Naaaaaw that's very wholesome.

[-]

KokoTheTalkingApe@reddit

Yep. Like a deer nuzzling a fucking fawn.

[-]

_Empty-R_@reddit

Why the emphasis on fawn? Or is the fawn specifically for fucking? Because it seemed a bit extra is all.

[-]

KokoTheTalkingApe@reddit

Why not emphasize it? It's a fucking fawn,

[-]

_Empty-R_@reddit

bro is crazy about fawns. fair enough.

[-]

Virtual_Area8230@reddit

What kind of sick fuck are you?

[-]

_Empty-R_@reddit

I don't think any kind. His wording seemed strange and out of nowhere. I'm poking at it. The internet is a fun place.

[-]

Fluffy_Muffins_415@reddit

Just booping the snoot

[-]

Pmyers225@reddit

Yeah apparently so

[-]

Brad__Schmitt@reddit

Numerous F-15 design elements.

[-]

GhostPepperDaddy@reddit

Who upvoted this lmao

[-]

Annual-Advisor-7916@reddit

I don't see anything like that? It's overall configuration seems to resemble the Convair Delta Dart a bit with an F-105 inlet.

[-]

Virtual_Area8230@reddit

Name one.

[-]

Brad__Schmitt@reddit

The shape of the wings.

[-]

Virtual_Area8230@reddit

Nope. Different leading edge angle, no camber on the leading edge, straight trailing edge, no rounded wing tip. Even the cut on the wing tip on the F-15 was pure coincidence. The original YF-15s had a different wing tip altogether that they clipped as a result of flight testing. They cut it off to fix wing buffeting. Literally sawsalled the thing off on the prototypes.

[-]

Pmyers225@reddit

Yeah or a MIG-21 or F-100

[-]

atxbikenbus@reddit

The dude in the background doomscrolling is the dead giveaway.

[-]

SkylineGTRR34Freak@reddit

Yep, that bare polished aluminium sure is something

[-]

Thermodynamicist@reddit

It reminds me of the MiG-21I.

[-]

richdrich@reddit

I do like the idea of a bleeding edge, hypersonic, Airforce One.

Maybe something like a Trident missile with pop out stub winds and a bicycle undercarriage, should the need arise to land it.

[-]

bannedUncleCracker@reddit

… first thought was F-100 …

[-]

Annual-Advisor-7916@reddit

Seems that you can build beautiful aircraft if you only care about speed and have no requirements of a low RCS. Sonic boom reduction seemingly wasn't a goal either, haha.

[-]

liberty4now@reddit

No space for radar in the nose...?

[-]

Unlucky-Debt5467@reddit (OP)

There is no nose, It's all INLET!!!
