I've seen some comments asking for comparisons to today's engines. Advantages are primarily in scale/form factor. Detonation engines, specifically the RDEs have been found to produce similar performance (thrust and Isp) with as low as 30% smaller engines (I forget if it's by mass or volume, but I think NASA has quoted some nunbers for this before, it's a quanitifiable decrease) than their counterparts with similar propellants and thrust class. Smaller engines = more payload or smaller vehicles or more utilization (landers, orbit adjustment) or ... the list goes on and on. They can work while being smaller because of the nature of the detonations: they move fast, they burn fast, and they burn hot, so combustion can occur "quicker" meaning the engines do not need to be as large to contain and divert the combustion for thrust. RDEs are revolutionary (pun intended) because they are a great step towards making space more accessible!

@TurboTaco2JZ

4 ай бұрын

I want to emphasize "because of the nature of the detonations: they move fast," Specifically the combustion event in an RDE is natively supersonic while conventional engines rely on traditional bell or de laval nozzles to make their subsonic combustion events (deflagration) produce a supersonic flow.

I was under the impression that (one of) the promises of detonation engines was a more efficient thermodynamic cycle. Off the top of my head, the figure was something like a 30% increase in Isp for Ficket-Jacobs cycles vs. Brayton/Humphrey - a paper I read a while back then argued that +5-15% was more realistic when considering nozzle effects. Have these final 5-15% proven to be unrealiseable in recent research? Higher thrust density is of course still a great motivator for further development, but a 5-15% increase in Isp is a monumental prospect

It's more than just increased thrust to weight ratio that these engines provide (though that in and of itself would make them worthwhile), it's also their fuel efficiency, that is nearly 50% better than conventional jet engines. Not only is it more powerful and smaller, it also allows for better fuel economy at all scales. It is early days and this is a still in development technology, but if it is used in commercial and space applications it will nearly double the range of current aircraft, with an even better thrust to weight ratio. For space applications, it is literally the holy grail, as the engines can give better thrust at the same size as rocket engines, but require half the propellant to achieve the same range, literally what all engineers dream of.

from how i understand a rotating detonation engine to work, they likely cant be throttled. the shock front will travel at a constant speed, and upsetting the fuel air mixture will likely just destabilize the system rather than cause "less" explosion like a conflagration engine would. the efficiency gain is theoretically like 25 to 30 percent, which is massive for rocket engines, whole new systems have been devised in the past just to save 10. the nature of an aerospike form factor means (assuming its not using ambient air for the detonation cycle) it should be at peak efficiency no matter what the surrounding atmosphere is, or isnt. it wouldn't need different engine nozzles for different pressures. in addition to fuel efficiency, the engine itself is much smaller than a conventional bell nozzle rocket. this saves weight that can either be used for more payload, or more fuel, or just plain ol smaller rockets. the challenge with it is stability of course. the idea of this kind of engine isnt new, and its taken a looooong time to get the detonation waves to be stable even when its sitting still on a test bed. so that will be the primary hurdle for this technology, is making them anywhere close to as reliable as conventional engines. another downside is that they are, currently, very small engines. in this sense i mean they havn't been scaled up to the kinds of thrusts of main stage rocket motors, they likely wouldn't be able to survive the forces or be stable at that scale. at least not yet. so these are late stage engines at best so far. and in terms of efficiency we've got far better options for "we're already in orbit and dont have to worry about raw thrust" than these things. though i suspect if nasa is testing them, its for a reason. so who knows, they probably know better than any of us what their use case is.

aerospike style engines dont have a bell. that lil cone in the middle is basically what the bell is. it allows the engine to dynamically change how the exhaust flows depending on pressure, so that it always has the optimal shape no matter the atmosphere. aerospikes are an old technology basically, and they've been tried with conventional conflagration type combustion before. the shuttle was originally intended to use them i believe but that was scrapped in favor of more tried and true technology. this is largly because the aerospike nozzle design is very hard to cool effectivly. a bell nozzle can have the fuel flowing around in rings through it, to act as coolant and to heat up the fuel before combustion. an aerospike cant do this. however this new alloy nasa is using for this particular aerospike seems to be able to handle the temperatures involved. at least at this scale

F1 Engine: I don't want that on me. Aerospike: *P O W E R !!!*

Long time working, Excellent.

Ох еще бы написали сколько у него расход на эти секунды и чем заправляют этого зверя.

I'd guess quite a bit less than a conventional engine with the same power output

Looks a lot like thrusters on Star Trek. Awesome

Holy Sh;t! That was a long run! They must have really been making progresson keeping the detonation front stable. Im super impressed!

this is absolutely insane

whoah, quite the airflow for such a small engine! not quite an EpsteinDrive, but we are getting there 😅

NASA just casually building engines most thought to be utterly impossible. Yet for some reason SpaceX keeps getting the headlines, while NASA's budget is cut. Sad.

I love how it sounds like screaming

Absolutely awesome!

Мы с пацанами такие паяльные лампы ещё в 80-х во дворе жгли 😂😂😂. Мы не знали, что это перспективный детонационный двигатель! 😅😅😅

Look Elon, it didn't blow up!

That's pretty rare for almost any rocket engine test, no matter who or what government does it.

RDE a bit of a mouthful. Spiral Fire. You can have that one on me. Amazing technology!

It ran for more than milliseconds. That’s freaking awesome

That... was... awesome

Well this is amazing!

Whoa! Fantastic guys!

Looks extra cool really

Top level. Amazing.

A thing of beauty. Truly. 🚀✨

NGAD thanks you for your contribution.

I've seen this in intagza video! Never thought I'd see one from NASA themselves!

I wonder what resource on that exhaust spike? It always was a main problem with air-spike rocket engines. Also, it was fully 3D printed or just there was a manual assembly?

Wow I cant wait for rockets with these guys 😃

Beautiful sound! 👌👍👌

No way! They finally pulled that off :O I read and watched a lot about the theory of these engines and even saw some small prototypes running but not yet a full scale one. I wish they would list some more data about it. Especially the ISP.
