Hypersonic Engine Test Breaks Record!

@Hermeus hybrid turbojet-ramjet hypersonic engine test is the real-life tech behind the Darkstar in Top Gun Maverick.

They are the 1st commercial company to ever hit this aviation milestone, achieving Mach 3 conditions in turbojet mode...and Mach 4 after switching to ramjet mode.

First flight is in 2023!

As someone once said: "Ramjets have only two settings - 'off' and 'vulgar display of power'." 🙂

Turbojet: “check out my shock diamonds, bro!” Ramjet: “hold my beer…”

[Dynastyk]

Jesus christ that ram jet lit up with a vengeance. Awesome

How do you mount that thing down and keep it from moving?

[harrisonlichtenberg]

Imagine you finally get a bead on a fighter with your radar and you fire off a SAM, only for the fighter engine to switch from projecting a cone of blue flame to a massive, infernal beam of orange fire and literally outrun your missile by 1.2 mach while flying parallel to sea-level.

Fun fact: they were forced to shut it down because it had reached the maximum capacity of the wind tunnel at Mach 4.4.

Imagine feeling the turbojet disengaging and get throw back at your seat when the ramjet aplies

When the Ramjet woke up it chose violence

[flaplaya]

I'm amazed at how many people understand the basic operations if a Ramjet

[winningjubbly]

It's like a very effective but hideously inefficient cigarette lighter built into the wall.

"Oh... well that was borin-HOLY SH$&!"

[rajathrajpatil]

Ramjets :- oh it was very hard 😅
Scramjets:- hold my beer

[flattirefire]

how did they get the ramjet to work without it moving and actively ramming in air?

[Sal-zxhs]

The way the ramjet engine fires up is something else

[sebsunda]

Great development!
And... They have a lot to tweak...
I see loads of flow instability in there...

[datcrow]

I thought the first afterburner was it, until the second one kicks in. Thats incredible

[letmefindout]

We will remember this day as the day Earth Day was 1.5 hours shorter. Thanks ramjet engine

[d-raptor]

This looks Insanely Awesome hope to see the New Hypersonic Plane around the Skies soon 🤩

[ozymandias]

One of my fav moments in TOP GUN: MAVERICK
when Mav switches on the scramjets and is thrown back against his seat. So much extra power with the scrams engaged, its literally a night and day difference🔥☀️

Looks like you guys figured out wave pulse detonation. The square exhaust is interesting. Looks like you went the way of the ls1, long rectangular ports...why?
