@engineeringexcellence: 🌀 3 cool facts about NASA’s Rotating Detonation Rocket Engine (RDRE): 1️ It detonates fuel instead of just burning it. Normal rockets rely on a steady flame, but this engine uses a continuous detonation - basically a controlled explosion that races around a ring-shaped channel over and over. That detonation-based combustion is more efficient, meaning more thrust from less fuel. 2️⃣ The whole thing is 3D printed. NASA built this engine using metal 3D printing, then hot-fired it for 251 seconds - over four minutes straight - without it melting down. Printing it this way makes the design lighter and faster to iterate on. 3️⃣ It’s being built for the Moon and Mars. In its record test it produced more than 5,800 pounds of thrust, enough to handle a lunar landing or a deep-space burn. NASA sees this as a key step toward lighter propulsion that can carry more payload further into deep space. The future of space travel might literally run on spinning explosions. 😳 #space #nasa #rocket #engineering #engine

A.R.D.T :

It’s just a regular rocket engine gang it’s just not a bell design

Pineapple :

Can’t beat spacex

RenegadeSosa :

this design took 3 years to make btw and only because we have no budget at nasa, give just the rocket engineers a 5% increase and we’d be on mars tomorrow

Charlie Turner :

Wait till he hears about every other engine ever

 :

“Powered by explosions”

Tyrin :

Most engines are combustion. But to have a detonation for your combustions is very different

WoodyT :

correct me if i'm wrong isn't every engine run on miniature explosions?

jonny :

the fact that we still have the combustion engine after all these years is starting to fatigue, there's proof that there are way more powerful engines using different energy sources

• Luke! • 🪖🪽🚩 :

Wait till he hears about the combustion engine

Ian 🥹 :

“Wdym that's just an engine” (explained in replies)

richiefox05 :

Damn near every engine is powered by explosions

Tanuki ⚠️ :

All engines are explosions.

Qizerole :

it's crazy how all the information in the world is at your fingertips and people still like to stay ignorant

𝙈𝙞𝙠𝙤® :

do basically a pulse jet with a different exhaust

PoliSciCam :

Nobody’s talking about the traffic light in the background goin crazy

Dildoslav :

The trying to be KSP too hard 💔

Radium 88636 :

Ok I know the science behind this one, it literally sends shockwaves around the engine cone and uses the shockwaves to both move fuel and generate thrust

gus >:) :

forcing hypergolics into a high compression reaction is one of those things that either works right or goes kaboom very badly. If we can make that a more efficient and reliable process, good.

jebediah_kerman14 :

aerospike engine from ksp

creme de la meow meow :

RX-0 Gundam Phenex :

Powered by explosions you say

Studdstuff 💽 :

It’s just a aerospike engine Brodie

THCrusader :

oh my goddddd this is the longest burn ive seen yet! ive been a nerd on these for so long and to finally have tests longer that 2 seconds is amazing 😭

🇺🇸 :

Every single combustion engine ever runs on explosions

Gmac3.0 :

Close enough, welcome back project orion
