Does anyone else think it's funny how turbo fans are mechanically complex but the easiest to make them work whereas scramjets are just a tube but are incredibly hard to make them work?

The biggest hurdle is going to be finding an acronym for the fancy dual mode rotating detonation turbo fanjet thingy.

This makes me really appreciate how truely advanced, for its time, the SR-71s J58 engine was.

To quote Perun: “When most have to chose an option, the US (and GE) just says yes.”

As a 74 year old geezer, much of this video zooms over my dome at hypersonic speed! Still an interesting presentation! Thanks.😵‍💫

This was an excellently created video, and I appreciate how you walked through all the technologies like we never heard them before to really grasp how big of a deal this is

This sounds like the aviation equivalent of cars going from carburetters to direct fuel injection 👍

And Kitty Hawk was only 120 years ago.. amazing technological advancements since then. I really appreciate the clear and concise explanations you give in "layman understandable" language... Bravo Zulu

YESSSSS! I’ve been waiting excitedly to hear more about RDEs for so long! They always seemed like they had such huge potential

Thanks for covering this, Alex. Love your videos!

NASA just fired a RDRE for over 4 minutes. That's more than enough for a rocket stage.

Some of your best content yet bro. Love the Deep dive on each part of the motor

🎯 Key Takeaways for quick navigation: 03:09 🚀 GE Aerospace has achieved a Hypersonic dual-mode Ramjet test with rotating detonation combustion, a breakthrough in propulsion technology. 05:41 ⚙️ GE aims to integrate four different engine technologies (turbofans, ramjets, scramjets, rotating detonation combustion) into a single combined system for Hypersonic flight. 07:43 🛫 GE's dual-mode Ramjet with rotating detonation combustion may overcome the velocity gap challenge, allowing efficient operation at speeds below Mach 3 and above Mach 2. 12:20 💡 Rotating detonation combustion offers greater efficiency in ignition, potentially leading to smaller, more fuel-efficient engines for Hypersonic aircraft. 23:07 📆 GE expects to demonstrate the rotating detonation combustion dual-mode Ramjet by 2024, with potential applications in Hypersonic reconnaissance planes or precision strike platforms. 24:34 💥 The U.S. publicly commits to non-nuclear Hypersonic weapons, focusing on conventional systems for immediate use, raising questions about the cost-effectiveness of $100 million missiles. 25:00 🔄 Reusable Hypersonic aircraft capable of delivering conventional munitions, collecting intelligence, and returning for another mission could shift the cost-benefit ratio and make Hypersonic speeds part of day-to-day operations. 25:27 🌐 The exact timeline for the deployment of such technology is uncertain, but breakthroughs like GE's rotating detonation combustion engine suggest that the day of practical, reusable Hypersonic aircraft is inevitable and closer than anticipated.

I watched the test-firing of the rotation, detonation engine the other day. It looks a lot better than when I first heard of the engine. From seconds to now minutes.

This was so well explained that I’m sharing it with my USAFA FB group. Hopefully it gets in front of the cadets so they understand the tech they will be flying soon. 👏

Just FYI, the great thing about a rotation detonation engine is that they work both in space and air. In space, for the RDE to work, you just need to carry liquid oxygen with you. You can throw LOX into an RDE and continue to fly with no problem.

Another great and informative video Alex, thank you for that. Hope you feel better soon and have a great holiday.

This is a legitimate great press + engineering synopses. -Aerospace Engineer

Been a while since ive watched Sandboxx. Im always left impressed at the delivery and ability to make an interested layman such as myself grasp whats being covered. Well done....as always.
